An exhaustive review of the physiologic effects of pneumoperitoneum is beyond the scope of this chapter medicine cabinet shelves 3ml bimatoprost with amex. Trendelenburg position also causes some difficulty in ventilating the patient and contributes greatly to hemodynamic changes (Falabella et al. Prolonged Trendelenburg position increases chest wall resistance and dead space, consequently decreasing the alveolar-arterial diffusion of oxygen. Pulmonary compliance and functional residual capacity are reduced; these effects are often more pronounced in obese patients (Ogunnaike et al. The cephalad displacement of the diaphragm and carina can cause the endotracheal tube to become displaced into the mainstem bronchus and upper airway and pulmonary interstitial edema can also result. In addition, pneumoperitoneum and Trendelenburg position can contribute to a reduction in the femoral venous flow and can increase the perioperative risk of venous thromboembolic events. Finally, corneal abrasion, despite use of protective eye tape, has been reported in 3% of patients in a case series of 1500 patients from a single institution (Danic et al. These authors thought that the steep Trendelenburg position places the patient at risk for coming into contact with the monitoring cables. They proposed using eye patches over the eye tape to prevent this and noted a reduction in their corneal abrasion rates. Surgical Anatomy Thorough knowledge of the anatomy of the anterior abdominal wall is mandatory for safe and effective trocar insertion. The umbilicus is approximately at the L3 to L4 level, and the aortic bifurcation is at L4 to L5. However, it is important not to track too far caudally in the subcutaneous tissue so that pelvic visualization is optimized. The left common iliac vein courses over the lower lumbar vertebrae from the right side and may be inferior to the umbilicus (Hurd et al. The common iliac arteries course 5 cm before bifurcating into the internal and external iliac arteries. The superficial epigastric artery, a branch of the femoral artery, courses cephalad and can be transilluminated, although this can be difficult in patients with darker skin color. At the level of the umbilicus, the superficial epigastrics and circumflex iliacs are 4. The inferior epigastric vessels course along the parietal peritoneum and are lateral to the medial umbilical folds but medial to the deep inguinal ring. The median umbilical ligament, the embryonic urachus, is attached to the apex of the bladder and extends to the umbilicus. The medial umbilical folds and the peritoneum overlying the obliterated umbilical arteries are the lateral landmarks of dissection of the parietal peritoneum during transperitoneal surgery into the space of Retzius. The upper margin of the undistended bladder dome lies several centimeters above the pubic symphysis. When the bladder is filled with 300 mL of fluid, however, the upper margin of the bladder dome is approximately 3 cm above the pubic symphysis. When considering the anatomy of the repair of pelvic organ support, a surgeon must keep in mind the three levels of support of the vagina. The endopelvic fascia (also referred to as the anterior pubocervical fascia and posterior rectovaginal fascia) contributes to the integrity of the wall of the vagina. All pelvic support defects-whether anterior, apical, or posterior-represent a break in the continuity of the endopelvic fascia and/or a loss of its suspension, attachment, or fusion to adjacent structures. The goals of pelvic reconstructive surgery are to correct all defects, thus reestablishing vaginal support at all three levels, and to maintain or restore normal visceral and sexual function. Operative Technique for Laparoscopic Sacral Colpopexy Operative Setup and Instrumentation Patent positioning is particularly important for laparoscopic and robotic cases. In our cases, the patient is usually placed on a disposable piece of egg crate foam that is secured to the operative table under the torso to prevent the patient from slipping toward the head of the bed with steep Trendelenburg position. A padded strap can be placed across the chest to further secure the patient (Alistrap, AliMed, Inc. Shoulder braces are another option, but these have been associated with brachial plexus injuries in some cases. Careful attention is paid to extremity positioning to prevent peripheral nerve injuries. The arms are tucked with the draw sheet with the wrist in a neutral, thumbs-up position. If needed, padding of the ulnar prominence and sled arm boards are used to further secure the arms. The lateral knee near the fibular prominence is typically padded to minimize risk of nerve injury in thin patients. The monitor screens should be placed laterally to the legs in direct view of the surgeon standing on the opposite side of the table. The scrub nurse should be in the center if two monitor screens are used; otherwise, the scrub nurse is located behind one surgeon and the electrosurgical unit or the harmonic scalpel on the opposite side. After the three-way Foley catheter and uterine manipulator (if needed) have been placed, the vaginal tray with cystoscope is set aside, if needed, for later use. A sterile pouch attached to each thigh is equipped with commonly used instruments, such as unipolar scissors, bipolar cautery, graspers, and laparoscopic blunt-tipped dissectors. For the standard suturing technique, the needle holder preference is determined by comfort of the surgeon. Conventional and 90-degree self-righting German needle holders (Ethicon Endo-Surgery, Inc. However, the handles are difficult to maintain and may pop open after extended use. Disposable suturing devices, such as the Endo-stitch (Covidien Surgical, Dublin, Ireland), have been introduced, but extracorporeal knot-tying is preferred because of technical facility and the ability to hold more tension on the suture. The choice of an open-ended or close-ended knot pusher for extracorporeal knot-tying depends on surgeon preference. Other options for knottying include various premade knots, such as clinch knots that do not require knot pushers and intracorporeal knots. Some surgeons have chosen to avoid knot-tying altogether by securing the mesh with a barbed suture (Quill by Angiotech, Vancouver, B. The use of barbed sutures is currently under investigation and is being compared to the conventional laparoscopic or robotic-assisted suturing approach (Tan-Kim et al. Although the use of barbed suture could greatly improve efficiency, there are potential risks of bowel obstruction with the use of barbed suture to close the peritoneum and vaginal cuff. Lumbosacral osteomyelitis and spondylodiscitis are rare but devastating complications of sacral colpopexy. Less than 30 cases are currently reported in the literature, and most are related to sutures, not tacks, placed in the presacral space (Grimes et al. Bone tacks, however, may penetrate the intervertebral disc or disc space to a greater depth than suture and could, theoretically, lead to lumbosacral osteomyelitis and spondylodiscitis. Both reusable and disposable ports may be secured with circumferential screws to prevent port slippage. Intraperitoneal Anatomy Assessment After the insertion of a 0-degree laparoscope (5 or 10 mm) through a respective 5 or 10 mm intraumbilical or infraumbilical cannula followed by intra-abdominal insufflation, an inspection of the peritoneal cavity is performed, delineating the inferior epigastric vessels just lateral to the medial umbilical folds, abdominal and pelvic organs, pelvic adhesions, and coexisting abdominal or pelvic pathology. Two additional trocars (5/12 mm disposable trocars) are placed under direct visualization in the right and left lower quadrants, lateral to the inferior epigastric vessels, and one or two additional 5 mm ports are placed at the level of the umbilicus, lateral to the rectus muscle, as previously noted. After the placement of the ancillary ports, the key anatomic landmarks of sacral colpopexy are noted: the middle sacral artery and vein; the sacral promontory with anterior longitudinal ligament; the aortic bifurcation and the vena cava (at the L4 to L5 level); the right common iliac vessels and right ureter (at the right margin of the presacral space); and sigmoid colon, which is at the left margin. The left common iliac vein is medial to the left common iliac artery and can be damaged during dissection or retraction. The rectovaginal septum is the posterior point of attachment of the sacral colpopexy mesh. The pubocervical fascia is the anterior point of mesh attachment during sacral colpopexy. During a sacral colpoperineopexy, the dissection is carried down to the perineum and bilateral levator ani muscles to which the inferior and lateral segments of a T-shaped mesh are attached. We use two additional trocars: a 5/12 mm disposable trocar with reducer in the right lower quadrant (if knot-tying from the right) lateral to the right inferior epigastric vessels and a reusable 5 mm port or an additional 5/12 mm disposable trocar, with reducer in the left lower quadrant lateral to the left inferior epigastric vessels. Trocars are placed laterally to the rectus muscle, approximately 3 cm medial to and above the anterior superior iliac spine. Anterior dissection is performed (taking care to avoid damage to the bladder) if a mesh is to be sutured to the pubocervical fascia or if enterocele repair is needed.

Many people find this problem socially incapacitating and stay home, thus minimizing social contact to avoid an embarrassing situation. Estimating the number of people afflicted with fecal incontinence is difficult because many do not mention the problem to their caregivers. In a study by Johanson and Lafferty (1996), only about a third of patients discussed their incontinence with their physicians. Others incorrectly describe their symptoms and may refer to their incontinence as "diarrhea," making it difficult for the physician to understand the problem without careful questioning. Definitions of fecal incontinence also vary from report to report, making comparisons difficult. Over $400 million is spent annually on adult diapers, and fecal and urinary incontinence are primary reasons for nursing home placement (outnumbering senile dementia). Fecal incontinence probably increases progressively with age, although it can affect all ages, even children. It affects men as well as women, and some studies find men affected more commonly than women.

Injury Obstetric (vaginal delivery/trauma) Surgical (fistulotomy, hemorrhoidectomy, sphincterotomy, stretch) Irradiation Trauma Congenital. Important questions to ask include duration of the problem, frequency of incontinence, time of day of incontinence, quality of stool lost, ability to control flatus, use of pads, frequency of bowel motions, problems with constipation or diarrhea, and effects of incontinence on daily life. Urgency may reflect inability of the rectal reservoir to store stool (as with diarrhea or proctitis) rather than a true sphincter problem. Equally important is to differentiate diarrhea from incontinence because many patients incorrectly interchange the two problems. Flatus is more difficult to control than liquid stool, and solid stool is the most easily controlled. Patients with incontinence of solid bowel motions without knowledge of the loss of stool are usually more distressed and reclusive than those with incontinence of flatus only. Additionally, the physician should obtain a thorough obstetric history: number of vaginal deliveries, duration of second stage of labor, previous episiotomy, use of forceps, perineal tears or infections, weight of babies, and unusual presentations at birth. A sexual history, including the effect of incontinence on sexual behavior, should be obtained. Other medical and surgical conditions must be ascertained, including back injuries, previous anorectal or abdominal surgeries, irradiation history, diabetes, multiple sclerosis, and scleroderma. They found that 35% of primiparous women and 44% of multiparous women had sphincter defects after delivery. A strong correlation was found between sphincter defects and the development of bowel symptoms, although only about a third of women with sphincter defects developed bowel symptoms. Incontinence may not appear until decades after the obstetric injury, so it remains to be seen how many of these women develop incontinence later in life. In the past, these patients, particularly women with delayed symptoms years after childbirth injury, were labeled with idiopathic incontinence. However, with the advent of more sophisticated evaluation techniques, defects in the sphincter complex have been found. Fecal incontinence also appears to be associated with urinary incontinence and pelvic organ prolapse. Besides obstetric injury, Physical Examination the physical examination starts with inspection of the anal area, looking for soilage of stool on the skin, and evidence of skin irritation. The patient is asked to squeeze and to simulate holding in a bowel movement to look for uniform circular contraction of muscle. Next, asking the patient to strain may show exaggerated perineal descent or prolapse of hemorrhoids or even the rectum. The anocutaneous reflex can be checked by rubbing the perianal skin gently (a Q-tip works well) and looking for the reflex contraction of the anal sphincter mechanism. Then the patient is asked to squeeze on the index finger in the anus as if she were holding in a bowel movement. A digital rectal examination checks for masses, occult or gross blood, fistula, and the presence of a rectocele. Scoring Scales for Fecal Incontinence Qualifying fecal incontinence has been difficult because many scoring systems have been introduced. This assessed general bowel habits, assessed presence and severity of fecal incontinence, measured symptoms related to pelvic floor dysfunction, and assessed risk factors for fecal incontinence. The other popular tool is the Wexner score that uses lifestyle alterations and wearing of a pad, in addition to incontinence to solids, liquid, and gas. In this score, zero is a score for perfect continence and 20 for complete incontinence. Rectal compliance can be determined by inserting a balloon and determining the minimal volume that the rectum can sense, then sequentially inflating the balloon to a volume that cannot be tolerated.

Open catheter: specify type (manufacturer) symptoms 8dp5dt purchase bimatoprost 3ml with visa, size, number, position, and orientation of side or end hole. Catheter-mounted transducers: specify manufacturer, number of transducers, spacing of transducers along the catheter, orientation with respect to one another; transducer design. Measurement technique: For stress profiles, the particular stress employed should be stated. The frequency response of the catheter in the perfusion method can be assessed by blocking the eyeholes and recording the consequent rate of change of pressure. Maximum urethral closure pressure is the maximum difference between the urethral pressure and the intravesical pressure. Functional profile length is the length of the urethra along which the urethral pressure exceeds intravesical pressure. Functional profile length (on stress) is the length over which the urethral pressure exceeds the intravesical pressure on stress. Pressure "transmission" ratio is the increment in urethral pressure on stress as a percentage of the simultaneously recorded increment in intravesical pressure. For stress profiles obtained during coughing, pressure transmission ratios can be obtained at any point along the urethra. If several pressure transmission ratios are defined at different points along the urethra, a pressure "transmission" profile is obtained. The information gained from urethral pressure measurements in the storage phase is of limited value in the assessment of voiding disorders. Quantification of Urine Loss Subjective grading of incontinence may not indicate reliably the degree of abnormality. However, it is important to relate the management of the individual patients to their complaints and personal circumstances as well as to objective measurements. To assess and compare the results of the treatment of different types of incontinence in different centers, a simple standard test can be used to measure urine loss objectively in any subject. The circumstances should approximate to those of everyday life, yet be similar for all subjects to allow meaningful comparison. This test can be extended by further 1-h periods if the result of the first 1-h test was not considered representative by either the patient or the investigator. Alternatively, the test can be repeated having filled the bladder to a defined volume. The total amount of urine lost during the test period is determined by weighing a collecting device such as a nappy, absorbent pad, or condom appliance. A nappy or pad should be worn inside waterproof underpants or should have a waterproof backing. For subjects not completing the full test, the results may require separate analysis, or the test may be repeated after rehydration. The test result is given as grams urine lost in the 1-h test period in which the greatest urine loss is recorded. Additional Procedures Provided that there is no interference with the basic test, additional procedures intended to give information of diagnostic value are permissible. For example, additional changes and weighing of the collecting device can give information about the timing of urine loss; the absorbent nappy may be an electronic recording nappy so that the timing is recorded directly. Record weight of urine lost during the test (in the case of repeated tests, greatest weight in any stated period). A loss of less than 1 g is within experimental error, and the patients should be regarded as essentially dry. When performing statistical analysis of urine loss in a group of subjects, non-parametric statistics should be employed because the values are not normally distributed. Subject drinks 500 mL sodium-free liquid within a short period (maximum 15 min), then sits or rests. Half-hour period: subject walks, including stair climbing equivalent to one flight up and down. If the test is regarded as representative, the subject voids and the volume is recorded. If the collecting device becomes saturated or filled during the test, it should be removed and weighed and replaced by a fresh device. The total weight of urine lost during the test period is taken to be equal to the gain in weight of the collecting device(s). In interpreting the results of the test, it should be born in mind that a weight gain of up to 1 g may be due to weighing errors, sweating, or vaginal discharge. If substantial variations from the usual test schedule occur, this should be recorded so that the same schedule can be used on subsequent occasions. If the patient experiences urgency, then he or she should be persuaded to postpone voiding and to perform as many of the activities in Section Typical Test Schedule (5a-e) as possible to detect leakage. The voided Procedures Related to the Evaluation of Micturition Measurement of Urinary Flow Urinary flow may be described in terms of rate and pattern and may be continuous or intermittent. Flow rate is defined as the volume of fluid expelled via the urethra per unit time. The calculation of average flow rate is only meaningful if flow is continuous and without terminal dribbling. The flow pattern must be described when flow time and average flow rate are measured. When voiding is completed without interruption, voiding time is equal to flow time. Opening time is the elapsed time from initial rise in detrusor pressure to onset of flow. In most urodynamic systems, a time lag occurs equal to the time taken for the urine to pass from the point of pressure measurement to the uroflow transducer. The following parameters are applicable to measurements of each of the pressure curves: intravesical, abdominal, and detrusor pressure. Premicturition pressure is the pressure recorded immediately before the initial isovolumetric contraction. Contraction pressure at maximum flow is the difference between pressure at maximum flow and premicturition pressure. The urethra does not generally behave as a rigid tube because it is an irregular and distensible conduit whose walls and surroundings have active and passive elements and hence, influence the flow through it. Bladder Pressure Measurements during Micturition the specifications of patient position, access for pressure measurement, catheter type, and measuring equipment are as for cystometry (see Section Cystometry). As yet available data do not permit a standard presentation of pressure/flow parameters. This form of presentation allows lines of demarcation to be drawn on the graph to separate the results according to the problem being studied. The group of equivocal results might include either an unrepresentative micturition in an obstructed or an unobstructed patient, or underactive detrusor function with or without obstruction. When estimating residual urine the measurement of voided volume and the time interval between voiding and residual urine estimation should be recorded; this is particularly important if the patient is in a diuretic phase. In the condition of vesicoureteric reflux, urine may reenter the bladder after micturition and may falsely be interpreted as residual urine. The presence of urine in bladder diverticula following micturition presents special problems of interpretation because a diverticulum may be regarded either as part of the bladder cavity or as outside the functioning bladder. The various methods of measurement each have limitations as to their applicability and accuracy in the various conditions associated with residual urine. Therefore it is necessary to choose a method appropriate to the clinical problems. The absence of residual urine is usually an observation of clinical value but does not exclude infravesical obstruction or bladder dysfunction. An isolated finding of residual urine requires confirmation before being considered significant. A motor unit action potential is the recorded depolarization of muscle fibers that results from activation of a single anterior horn cell. Muscle action potentials may be detected either by needle electrodes or by surface electrodes. Needle electrodes are placed directly into the muscle mass and permit visualization of the individual motor unit action potentials. Surface electrodes are applied to an epithelial surface as close to the muscle under study as possible.

Finally, hyperglycemia in labor aggravates the risk of neonatal hypoglycemia and is associated with lowered Apgar scores. This chapter will review the aforementioned neonatal complications of pregnancy in diabetes and their management. For instance, the caudal regression syndrome, an extremely rare malformation, is seen almost exclusively in these infants. If performed, barium enema reveals a uniformly narrowed colon from the splenic flexure. It has been calculated that an increase in HbA1c of 1% of the total hemoglobin may cause a decrease in the P50 of approximately 0. A subsequent left shift of the oxygen dissociation curve occurs, which may have a significant, deleterious impact on oxygen release. The prevalent theory behind these findings is that in the presence of extra fuels or of hyperinsulinemia, the metabolic rate of the placenta increases together with the oxygen consumption rate depriving the fetus of oxygen. Visceromegaly is not only due to organ hypertrophy and may also be due to increased fat storage, such as evidenced in the liver of such infants. After the introduction of insulin in 1921, diabetic women became pregnant at increasing rates, but perinatal mortality was very high and remained so until the 1950s, where it still was about 20%. The exact incidence of neonatal hypoglycemia is, however, extremely difficult to assess, in particular because of the multiple definitions used to describe it66 and because its occurrence is highly affected by the degree of maternal glycemic control. Their blood concentrations of fatty acids are reduced,73,74 plasma concentrations of ketones are no different than those of nonhypoglycemic controls,74 and blood concentrations of plasma amino acids are little, if any, affected by hypoglycemia. First, neonatal asphyxia may aggravate hypoglycemia, due to increased glucose demands during anaerobic metabolism. Furthermore, as pointed out by Cornblath and Scwartz, "normal values" may be defined using many different approaches. Other authors have proposed a neurophysiological definition to neonatal hypoglycemia, based on a threshold blood glucose concentration associated with disturbed neurophysiological function, such as auditory evoked response waveform. Whether poor glycemic control favors the development of urogenital infection or urogenital infection precipitates the loss of glycemic control is unknown. This team may be composed of physicians, neonatal nurse practitioners, midwives, or respiratory therapists with formal training and experience in neonatal resuscitation. These professionals should apply all standards and techniques described in the Neonatal Resuscitation Program, program developed as a joint effort of the American Heart Association, and the American Academy of Pediatrics. Otherwise, its management may be well conducted in a well baby nursery, provided that the following steps guidelines are addressed and facilities are available: 1. Complete physical examination by a trained physician as soon as possible after birth. We base the following recommendations upon those suggested by an expert committee who published on the topic. Glucose reagent strips are commonly used in the newborn nurseries to screen for low blood glucose concentration. These methods should only be considered as a screen or an estimate because they may not be reliable and should not be used as the basis of a diagnosis. However, the final diagnosis should depend on the laboratory plasma glucose values. The higher therapeutic goal includes a significant margin of safety in the absence of any data evaluating the correlation between glucose levels in this range and long-term outcome in full-term infants. However, some malformations may not be detected by antenatal ultrasonography, such as a small ventriculoseptal defect; thus, we advise performing echocardiography only when signs or symptoms pointing to a possible cardiac problem are present. We believe that a routine hematocrit value should be obtained, preferably from a venous sample, to screen for neonatal polycythemia at the time of peak hematocrit, that is at two to four hours of life.

The nineteenth century was the dawn of a new era in the surgical treatment of vesicovaginal fistulas medications hypertension cost of bimatoprost. In 1834, Jobert de Lamballe (1852) successfully repaired a small number of fistulas using pedicled skin flaps (autoplastie vaginale par la methode indienne). A second technique (autoplastie par glissment ou par locomotion) later enabled him to close a greater number of fistulas. This technique involved dissecting the bladder from the cervix and vagina with the additional use of curved releasing incisions in the vagina to facilitate mobilization and closure without tension. In a letter to the Boston Medical and Surgical Journal in August 1838, Mettauer (1840) of Virginia stated that he had repaired a vesicovaginal fistula about the size of a halfdollar piece using lead wire, with good results. On June 21, 1849, in an eight-bed infirmary on Perry Street in Montgomery, Alabama, J. Using the genupectoral position, a bent pewter spoon as a vaginal speculum, and reflected light from a mirror, Sims denuded the fistula edge, closing the defect in one layer with fine silver wire applied with leaden bars and perforated shot. On the eighth day, Sims reexamined the patient and noted that the wound was well healed. In 1852, he published his classic paper "On the Treatment of Vesicovaginal Fistula" in the American Journal of Medical Sciences. He deprecated both cautery as advocated by Dupuytren for small fistulas and obturation of the vulva as practiced by Vidal de Cassis (whereby the bladder and vagina are converted into a common reservoir for urinary and menstrual discharge). Sims insisted on the liberal use of opium for perioperative analgesia and stressed the importance of postoperative bladder drainage with a urethral catheter. He later designed a silver sigmoid-shaped, self-retaining catheter for this purpose. His greatest contribution to obstetric care was arguably his insistence that frequent catheterization of the bladder in labor, together with the judicious use of forceps for second-stage delay, would prevent the majority of labor-related vesicovaginal fistulas. In 1861, Collis of Dublin advocated the flap-splitting technique, whereby the anterior vaginal wall is widely dissected from the bladder with separate closure of the two defects. In the 1880 and 1890s, Trendelenburg and von Dittel reported failed attempts at fistula repair, using extraperitoneal and suprapubic approaches, respectively. Schuchardt (1893) also devised a parasacral incision, which permitted better access to high fistulas, particularly when associated with vaginal stenosis. The discovery of antibiotics and the development of general and regional anesthesia contributed significantly to the surgical treatment of vesicovaginal fistulas in the twentieth century. Knowledge of effective repair of genitourinary fistulas became more widely disseminated with the publication of the Vesico-Vaginal Fistula (Moir, 1961). Greater international attention was brought to the immense problem of genitourinary fistulas in developing countries with the foundation of the Second Fistula Hospital in Addis Ababa, Ethiopia, in 1975, and the report of 1789 fistulas repaired during an 11-year period from Nigeria (Ward, 1980). Epidemiology and Etiology Most of the literature on the etiology, diagnosis, management, and prevention of lower urinary tract fistulas consist of expert opinions, case series, or cohort studies, with few randomized controlled trials. Many of the studies are based on experiences with obstetric fistulas, which primarily occur in women in developing countries. Research in these environments is often limited by resource scarcity and plagued with short-term follow-up periods. It is important to review the information presented in this chapter with these limitations in mind. Lower urinary tract fistulas occur secondary to a defect or vulnerability in the wound-healing process. Wounded tissue undergoes four phases of healing: coagulation, inflammation, fibroplasia, and remodeling. During the fibroplastic phase, collagen is laid down, reaching its peak on the seventh day after injury and continuing for 3 weeks. Between the first and third weeks, healing is most vulnerable to hypoxia, ischemia, malnutrition, radiation, and chemotherapy, so this is the time when most fistulas present. Conditions known to interfere with wound healing are associated with an increased risk of fistula formation, including diabetes mellitus, smoking, infection, peripheral vascular disease, chronic steroid use, malignancy, and previous tissue injury. Obstetric Fistulas the vast majority of vesicovaginal fistulas that occur in women in developing countries are caused by obstetric trauma. Obstetric fistula occurs when women experience prolonged, obstructed labor without access to emergency obstetric care allowing cesarean section. Prolonged pressure of the fetal head within the maternal pelvis results in necrosis of the pelvic tissue trapped between the fetal head and the maternal bony pelvis, which leads to tissue breakdown and eventual fistula formation. Prevalence estimates of obstetric fistula from demographic health surveys and other population-based surveys range widely from 0. However, the accuracy of these figures is unknown as they are based on expert opinions or extrapolation of expert experiences from hospital-based settings. Additionally, many of the population-based surveys are limited by the use of different, unvalidated, case-defining questions without confirmatory examinations. Many women are unaware that the condition is treatable and thus lack appropriate care due to social isolation as a result of their urine leakage symptoms. Poverty, lack of knowledge, long travel distances, and waiting lists deter women from traveling to major centers and undergoing care. As a result, many of these women live with fistula symptoms for many years and face abandonment by their families and isolation from society. A study of five countries in Southeast Asia found that 62% to 92% of afflicted women were divorced from their husbands and rejected from society. Studies from Africa also demonstrated high divorce rates, with a high prevalence (73%90%) of psychological conditions such as depression. The risk factors that lead to obstetric fistula development are incompletely understood. Most of the published studies are from Africa, from hospital-based descriptive case series, and may have limited generalizability. The commonly accepted prototype of the fistula patient is a poor and malnourished young woman of limited formal education from a rural area, who attempts a home delivery without a trained birth attendant, which results in prolonged, obstructed labor and delivery of a stillbirth infant. In various hospital-based case series, the mean age of women with obstetric fistula ranges from 19 to 35 years,and in approximately half (31%-81%) of women, the fistula developed during their first delivery. Although traditional practices such as female circumcision have not been shown to be associated with an increased risk for fistula development, other traditional practices such as Gishiri cutting. Several case series have documented short stature in women with fistulas, with average heights of 149 to 156 cm, and smaller foot sizes. Other possible anthropomorphic risk factors include reduced pelvic dimensions (caused by early childbearing, chronic disease, malnutrition, and rickets). Even after presenting to a hospital, a woman may still develop a fistula caused by trauma from forceps or other instruments used to deliver stillborn infants or perform surgical abortion. Vesicovaginal fistulas can follow cesarean delivery or peripartum hysterectomy, particularly in the presence of distorted anatomy. Gynecologic Fistulas In developed countries, the major cause of genitourinary fistulas is abdominal surgery and, more recently, laparoscopic and robotic surgery, especially when hysterectomy is performed. In the United States, vesicovaginal fistulas are caused by benign gynecologic surgery (80%); obstetric events (10%); surgery for malignancies of the cervix, uterus, or ovary (5%); and pelvic radiotherapy (5%). Four-fifths of postsurgical fistulas in the developing world are the result of operations performed by obstetrician-gynecologists, and the remaining fifth is divided among urologists, colorectal, vascular, or general surgeons. Predisposing risk factors for lower urinary tract fistulas include intraoperative cystotomies that extend into the trigone or bladder neck, hysterectomy for a large uterus, intraoperative blood loss greater than 1000 mL, and tobacco use (Duong et al. Other risk factors include prior pelvic irradiation, pelvic adhesions, endometriosis, previous pelvic operations including cesarean section, history of pelvic inflammatory disease, diabetes mellitus, and concurrent infection. Gynecologic surgery was responsible for 82% of the fistulas, obstetric events for 8%, radiation therapy for 6%, and trauma or fulguration for 4%. Seventy-four percent of fistulas resulted from gynecologic surgery for benign conditions such as fibroids, dysfunctional uterine bleeding, prolapse, incontinence, and endometriosis. This review included 53 patients with urethrovaginal fistulas, of whom 10 also had a vesicovaginal fistula. Antecedent events included vaginal surgery for incontinence or cystocele, urethral diverticulum repair, treatments for gynecologic cancer, and the use of forceps. The reported incidence of vesicovaginal fistula after hysterectomy is approximately 1 in 1300 surgeries.

Histologically, these influences are reflected by highly variable villous histology ranging from hyperplastic (reflecting growth promoting effects) and accelerated maturation and other lesions reflecting diabetes associated vascular dysfunction. However, as the prevalence of diabetes and obesity rises, the extent to which they contribute to adverse pregnancy outcome and the number and complexity of pathways by which diabetes and obesity contribute to adverse pregnancy outcomes have become clearer. Diabetes and obesity share a spectrum across which different combinations of growth-promoting and growth-restricting factors, as well as developmental and immunologic dysregulation, may alter growth trajectories of both fetus and placenta. The pathways linking diabetes and obesity clinically, and oxidative stress and inflammation pathologically, are numerous and are detailed elsewhere in this text. The working hypothesis underlying the following discussion is that diabetes and/or obesity may affect the maternal uterine environment by altering ovarian, endometrial, and/or uteroplacental vascular function via the mediators of oxidative stress and inflammation. However, the effect of diabetes on the fetoplacental environment may be more direct, altering the presence and distribution within the placenta of extracellular matrix molecules known to be important in normal placentation such as fibronectin8 and affect trophoblast morphology in a mouse model of diabetes. Changes recognizable in the delivered placenta involve macroscopic, microscopic, 42 the Diabetes in Pregnancy Dilemma ultrastructural, and physiological changes. This review will focus on placental macroscopic (gross) and microscopic (histological) common but neither ubiquitous in nor specific for diabetes and/ or obesity. A brief outline of important aspects of normal placental growth and development across gestation is followed by a review of evidence that diabetes and/or obesity may disturb those aspects of placental growth. Finally, the principal histopathology types and their associations with diabetes and/or obesity will be reviewed. We will present new analyses from a recent and comprehensive birth cohort that the placental dysfunction associated with maternal diabetes has its origins in the early conceptus. Its growth is generally considered to be the sine qua non for the healthy growth of a euploid fetus. At the earliest stages of pregnancy, growth of the placenta requires sufficient ovarian function to produce the amounts of steroids needed to prepare the endometrium for pregnancy. As noted by Boyd and Hamilton,11 some of the early decidual changes of the endometrium can be simulated by exogenous supply of luteal phase steroid hormones. Histologically, this area appears to show increased permeability at the time of implantation,10 which may increase the local concentrations of important nutrients. Within a week postconception, the embryo is partially embedded in the endometrium. Although there is endometrial cell death, there is no "disorderly" necrosis, despite obvious signs of tissue destruction16; the invasive cells are actively involved in the phagocytosis of maternal cell debris.

Several studies have reported an increased risk for hypertension and preeclampsia medications for high blood pressure order 3 ml bimatoprost otc,128,129 whereas others have disputed this relationship. Therefore, the risk to the fetus increases continually in relation to the increased level of maternal glycemia up to a level to which glucose toxicity reaches its maximum effect. It is not possible to identify the exact threshold of glycemia that will make an absolute demarcation between the normal and the compromised fetus. However, it is possible to identify a glucose threshold for the majority of fetuses at risk. Although some high- and lowrisk fetuses will be missed at the outlying end of the threshold, the threshold provides a guideline for the practitioner that helps maximize the potential for enhanced perinatal outcome. Despite the common recommendations of fixed criteria for glucose control, the reader needs to remember that achieving different glucose thresholds will diminish the rates for different complications. Therefore, any improvement in the abnormal diabetic profile in the patient may be beneficial. The threshold that will decrease the rate of fetal anomalies will not decrease the macrosomia rate. Understanding this concept explains several "paradoxes" in the literature regarding infant morbidity of the diabetic mother as well as the lack of uniformity in study design that limits comparison.

Although it principally focuses on food planning, in recent years, it has encompassed physical activities (which will be discussed in Chapter 17, devoted to exercise and pregnancy). To maintain glucose homeostasis and assure adequate maternal and fetal nourishment, while avoiding both undernutrition and overnutrition, maternal nutrient intake requires balancing of amino acids, omega-3 fatty acids, folic acid, iron, copper, and other minerals as well as carbohydrates, fat, and protein to assure adequate weight gain for the developing fetus. Activity and planned exercise are generally continued at the same level of intensity as the prepregnancy level unless an intercurrent event suggests otherwise. Diabetes in pregnancy requires that adequate weight gain occurs to promote fetal growth while addressing a physiological state that risks sudden and sustained hypo- and/or hyperglycemia. Simultaneously, the nutrient intake must be synchronized with the antidiabetic medications, which are required in the majority of women with diabetes in pregnancy to prevent dysglycemia.

The myogenic hypothesis suggests that overactive detrusor contractions result from a combination of an increased likelihood of spontaneous excitation within smooth muscle of the bladder and enhanced propagation and subsequent spread of contractile signals via cell-to-cell coupling medications in canada bimatoprost 3ml low cost. A pelvic examination should include a thorough inspection of the perineal area and vulva, looking for excoriation, vaginal discharge, or atrophy, suggesting estrogen deficiency. Vaginal examination should include assessment for pelvic organ prolapse, pelvic muscle function, atrophy, and anatomic abnormalities. The urethra can be palpated through the anterior vagina, checking for a mass or purulent discharge from the urethral meatus consistent with a urethral diverticulum. Pelvic floor muscle function should be described by pelvic muscle tone at rest and by the strength of voluntary contraction. Muscle tone and strength can be subjectively described as strong, weak, or absent; or described by a validated graded system, such as the Oxford system, usually on a scale from 1 to 5. Determining the postvoid residual, either with ultrasound or by performing straight catheterization, will help rule out occult voiding dysfunction as well as detrusor hyperactivity with impaired contractility. Pelvic organ prolapse should be evaluated, specifically commenting on the support of the anterior, apical, and posterior vagina. Rectal examination should also be performed to rule out fecal impaction and rectal mass and to assess sphincter tone. Evaluation An important aspect of the evaluation is appreciating the quality of life impact that these symptoms are creating. Standardized quality of life questionnaires are available and can be administered. In addition, specific questions about pelvic organ prolapse, defecatory dysfunction, and sexual dysfunction are important. A thorough medical history should be taken, as well as a surgical history with emphasis on previous bladder or gynecologic surgery. A review of all current prescription medication that the patient is taking is vital. As previously mentioned, bacteriuria may cause detrusor overactivity, which sometimes resolves after the infection has been treated. Urine cytology should be performed to rule out neoplasia in patients with chronic irritative bladder symptoms, particularly in elderly patients and those with microscopic hematuria. Voiding Diary In addition to history-taking, patients can be mailed or given a voiding diary to fill out 48 h before their office visit, usually over a weekend to avoid the possible interference of work. Also, significant changes can be made with daily fluid intake and medication to decrease urinary loss. Follow-up charts are useful to provide evidence to both patient and clinician of treatment response, particularly when bladder retraining is used. The volume voided in 24 h was a mean of 1730 mL (range 4373861 mL) and the mean frequency was 7 (range 2-13) voids per day. One of the interesting findings from this study was that a linear relationship was found between the functional bladder capacity and the volume voided in 24 h. The authors speculate that an increased bladder capacity may be a way to compensate for increased volume without increasing voiding frequency. Physical Examination A physical examination should include a general physical, neurologic, and pelvic examination. Neurologic studies should include a brief mental status examination and evaluation of cranial nerves and deep tendon reflexes. Muscle strength can be assessed by having the patient actively move against resistance, such as shrugging her shoulders against downward pressure. Deep tendon reflexes should be checked at the biceps (C5-C6), triceps (C7), knee (L3-L4), and Achilles tendon (L5-S2). Spinal cord segments S2, S3, and S4 contain important neurons involved with micturition. The anal sphincter and pelvic reflexes are important indicators of sacral cord integrity. Voluntary contraction of the external anal sphincter indicates a minimum level of integrity of pelvic floor innervation. Stroking the skin lateral to the anus elicits a reflex anal sphincter contraction. The bulbocavernosus reflex involves tightening of the bulbocavernosus and ischiocavernosus muscles by tapping or squeezing the clitoris. C, Cough-provoked detrusor instability (intravesical instead of true detrusor pressure is depicted here). Cystometry is the mainstay of investigation for bladder storage function and is the only method of objectively diagnosing detrusor contractions. Sometimes, the provocation needed to reproduce a detrusor contraction cannot be performed in a laboratory setting. This problem has been demonstrated in numerous ambulatory monitoring studies in which symptomatic patients had a stable detrusor during filling in the urodynamic laboratory but had uninhibited contractions when monitored on a continuous basis. Testing should always be performed with the patient in a sitting or erect position because supine filling cystometry alone fails to uncover a significant proportion of bladder overactivity. This resource is supported by an educational grant from Astellas Scientific and Medical Affairs, Inc. Further data is needed to determine if the cost, invasiveness, and potential morbidity outweighs the benefits and risks of empiric treatment. Urethral pressure studies add little to the diagnosis of detrusor overactivity or to the differentiation of patients with stress incontinence from those with urgency incontinence. Patients who had urethral relaxation before detrusor contractions responded better to sympathomimetic drugs, whereas patients without urethral pressure changes responded more favorably to anticholinergic drugs. In another study, urethral instability occurred in 42% of patients with detrusor overactivity and was strongly associated with the sequence of urethral relaxation before an unprovoked contraction. This study concluded that, based on a urethral response, two subgroups of detrusor overactivity may exist. This observation is important because these patients are probably unable to voluntarily contract the external sphincter at the moment of the detrusor contraction, thus, they are unable to inhibit urine loss. The finding on physical examination of a mass below the urethra consistent with a urethral diverticulum may be another indication for cystourethroscopy. The clinician should always pay attention to occupational exposures or medications that could potentially be bladder irritants. Definitive indications for cystourethroscopy include microscopic hematuria and abnormal urine cytology. Cystoscopy should also be considered if the diagnosis is in doubt or if the patient shows no response to appropriate behavioral and pharmacologic therapy. Treatments range from nonsurgical to surgical with varying degrees of invasiveness and monetary investment. Patients are given preprinted cards, on which they record voiding (daily and nightly), involuntary leaking episodes, and occurrences that precipitate incontinence. Patients are instructed to make an earnest effort to follow the schedule during the day, attempting to suppress urgency and voiding only at the scheduled times regardless of the presence or absence of urinary urgency. Patients are instructed to contract their pelvic floor muscles when they feel urgency and impending urgency incontinence, to suppress involuntary bladder overactivity. Follow-up visits are scheduled every 1 to 2 weeks, at which time the cards are reviewed with the patient. Enthusiastic patient contact, reassurance, good longterm support, and follow-up are important. Because the success rate is so good and the therapy involves low cost bladder retraining drills should be the first line of therapy in patients with detrusor overactivity. Biofeedback Biofeedback is a form of patient reeducation, such that normally unconscious physiologic processes are made accessible by auditory, visual, or tactile signals, while attempts are made to modify the process by manipulating the signal presented to the patient. This method has been used with some success in the treatment of autonomic dysfunctions, hypertension, and cardiac dysrhythmias. As an example of how biofeedback can be used to treat detrusor overactivity, after cystometry is explained to the patient, bladder filling begins and an audible signal is used to let the patient know that her bladder pressure is rising. The bladder is repeatedly filled while the patient attempts to inhibit detrusor contractions. Individual treatment sessions are approximately 1 h and are repeated weekly for up to 8 weeks.

Several case series discuss the feasibility and safety of combined laparoscopic vaginal and rectal prolapse procedures symptoms 7 days after embryo transfer generic 3ml bimatoprost mastercard. Median operative time was 125 min (range 50-210 min), with only one conversion to an open procedure. Patients had only minor postoperative complications (three fecal impactions, one port-site infection, one urinary tract infection, and one chest infection). Although no patient developed recurrent full thickness rectal prolapse, four had symptoms of postoperative residual hypertrophied rectal mucosal prolapse. Wexner fecal incontinence scores improved in 91% of patients and obstructed defecation resolved in 80%; three patients, however, reported newonset minor issues with defecation. Although poorly defined, pelvic pain resolved in all but one patient postoperatively. A recent systematic review on ventral rectopexy for rectal prolapse and rectal intussusception included 12 case series with a total of 728 patients (Samaranayake et al. Seven studies utilized a ventral rectopexy with posterior rectal mobilization to the pelvic floor (Orr-Loygue procedure), and five utilized ventral rectopexy without posterior rectal mobilization. The most common complications were urinary tract infections (N = 11) and port-site or incisional hernias (N = 16). Another recently published systematic review included 866 patients from 13 observational studies and examined the use of biologic and synthetic mesh for laparoscopic ventral rectopexy (Smart et al. Although there were only 99 patients with a biologic implant, they noted that there was no difference in recurrent rates (3. Other studies have compared operative, clinical, and cost results between ventral rectopexy performed laparoscopically and robotically (Wong et al. Overall, small comparative studies report no difference in perioperative complications. One study found similar short-term outcomes for robotic and laparoscopic procedures. Another prospective cohort of 82 patients found recurrent rectal prolapse more frequent after laparoscopic and robotic procedure compared with open rectopexy (27%, 20%, and 2%, respectively; P = 0. Robotic-assisted laparoscopy, however, may help with ease of suturing for those colorectal surgeons who are not accustomed to suturing laparoscopically. Their cohort included 42 patients (38 women) who underwent laparoscopic ventral rectopexy with Marlex mesh secured to the rectum with Ethibond suture and fixated to the sacral promontory with either sutures or staples. They were followed for a median of 61 months (range 29-98 months), there were no major postoperative complications and no readmissions. The fecal incontinence score improved in all but three of the fecally incontinent patients. Laparoscopic Uterosacral Ligament Vaginal Vault Suspension In order to suspend the vaginal apex to the uterosacral ligaments, the surgeon must dissect and delineate the pubocervical and rectovaginal fascias. This stitch is tied extracorporeally, and the opposite uterosacral ligament is reattached in the same fashion. If concomitant enterocele repair is performed, the uterosacral ligaments may be tagged before dissection of the posterior vagina and rectovaginal septum. This allows the uterosacral ligaments to be easily identified for subsequent suspension. Peritoneal incisions may be made laterally to the uterosacral ligaments to prevent ureteral kinking with uterosacral suture placement. The apical vault repair described by Ross (1997) reestablished the lateral and posterior paracervical rings of endopelvic fascia by bringing the rectovaginal septum and cardinal/ uterosacral ligaments together. After the peritoneum is dissected off the vaginal apex and the pubocervical fascia and rectovaginal septum are identified, a no. The first stitch is placed in the uterosacral ligament approximately 3 to 4 cm proximal to the vaginal apex. This repair differs from the uterosacral ligament vaginal vault suspension by placement of purse-string sutures resulting in uterosacral ligament plication. One hundred eighteen patients were included, with 96 patients in the vaginal group and 22 in the laparoscopic group. Vaginal uterosacral suspension was performed with permanent and delayed absorbable suture in the manner described by Barber et al. Intraoperative cystoscopy was performed in all cases after administration of indigo carmine. Concomitant repairs were performed either laparoscopically or vaginally, as indicated. Concurrent repair of anterior compartment defects was performed differently, with paravaginal repair utilized more frequently in the laparoscopic group. Uterosacral ligaments have been sutured into the pubocervical and rectovaginal fascias. Vaginal apical support was significantly better in the laparoscopic uterosacral uterine suspension group compared with the vaginal surgery group (-9 versus -7. Blood loss and postoperative hospitalization were less in the laparoscopic group (72 mL versus 227 mL; P < 0. There were no intraoperative or postoperative complications, but three patients in the vaginal surgery group underwent repeat surgeries for apical prolapse between 37 and 59 weeks postoperatively. Longevity of laparoscopic uterosacral vault suspension was further examined by Lin et al. Moschcowitz and Halban Procedure the Moschcowitz procedure is performed laparoscopically in the same manner as it is during laparotomy. The ureters should be examined carefully during and after the Moschcowitz procedure. Little risk of ureteral compromise is present with this procedure; however, it is important to visualize the ureters after all sutures are tied. Laparoscopic Enterocele Repair the enterocele sac is dissected laparoscopically or vaginally so that the endopelvic fascial defects are identified, and the pubocervical fascia and rectovaginal fascia are delineated. If the enterocele is large, the surgeon excises redundant peritoneum and vagina by the vaginal route, taking care not to foreshorten or narrow the vaginal apex. Extracorporeal knot-tying is performed after each stitch is placed, which is often performed concomitantly with a uterosacral ligament vaginal vault suspension so that apical suspension is reestablished. To date, most laparoscopic colposuspensions have been done for only primary stress incontinence because of difficulty in dissecting retropubic adhesions. Many patients choose laparoscopic and robotic-assisted surgery because of the smaller, more cosmetic incisions, shorter recuperation time, and rapid return to work. Access Route: Extraperitoneal or Intraperitoneal the utilization of an extraperitoneal or intraperitoneal approach depends on whether concomitant intraperitoneal procedures are being performed, on whether the patient has had previous abdominal wall surgery, and on surgeon preference. Previous retropubic surgery is a contraindication for extraperitoneal approach, and low transverse or midline incisions make the dissection more difficult and prone to failure. Some surgeons report less operating time, easier dissection, and fewer bladder injuries with the extraperitoneal route. This route is sometimes easier because the balloon performs the majority of the dissection. We prefer the intraperitoneal approach because it allows a larger operating space for safe, secure, comfortable handling of the suture. Furthermore, a culdoplasty or other intraperitoneal surgery can be performed concomitantly. The intraperitoneal approach begins with insertion of the 0-degree laparoscope (5 mm or 10 mm) through a respective 5 or 10 mm intraumbilical or infraumbilical cannula followed by intra-abdominal insufflation. Inspection of the peritoneal cavity is performed, delineating the inferior epigastric vessels, abdominal and pelvic organs, pelvic adhesions, and coexisting abdominal or pelvic pathology. Two additional trocars (a 5 mm and a 5/12 mm or two 5/12 mm ports) are placed under direct visualization, one on each side, as previously noted. All trocars are nondisposable except the 5/12 mm trocar through which 5 and 10 mm instruments are introduced. Some surgeons backload the suture through 5 mm ports and introduce and remove needles through the skin incisions. However, trauma to the subcutaneous tissues and inferior epigastric vessels may result with this technique. Furthermore, it is difficult to use this technique with sutures with doublearmed needles. The bladder is filled with 200 to 300 mL sterile water or saline through a 16 French, three-way Foley catheter (indigo carmine or methylene blue is optional). Using sharp dissection with electrocautery or harmonic scalpel, a transverse incision 2 cm above the bladder reflection between the medial umbilical folds is made.
