Incontinence can be broadly divided between that requiring surgical intervention and that requiring medical or behavioral therapies. In general, incontinence related to primary nocturnal enuresis or infrequent voiding tends to resolve with time and does not require surgery. The following sections address the clinical presentation, evaluation, and treatment of lower urinary tract abnormalities associated with urinary incontinence in girls. Nocturnal Enuresis Primary nocturnal enuresis is defined as persistent nighttime wetting past the age of 5 years. Nocturnal enuresis occurs in approximately 20% of 5-year-old children and is more common in boys than girls [3]. Diagnosis and treatment of nocturnal enuresis is multifactorial, relying on both the pathophysiology and psychological analysis of the child. Simple behavioral strategies to help children gain control include star charts and other reward systems, fluid restriction, bladder training (including retention control training), and wakening. These are often used as a first attempt to control bedwetting and can be undertaken by families with less professional involvement [4]. Daytime and nighttime symptoms such as wetting, urgency, and frequency may be treated with anticholinergic medications as well as biofeedback [8,9]. Dysfunctional Voiding and Voiding Dysfunction Although the terms "dysfunctional voiding" and "voiding dysfunction" are often used interchangeably, such usage is incorrect. These children have difficulty relaxing their pelvic floor musculature and habitually contract the urethral sphincter during voiding. As a result, day- and nighttime wetting, urinary frequency, urgency, hesitancy, urinary tract infections, constipation, and/or encopresis is common. Botulinum toxin A (Botox) can be injected into the external sphincter in severe cases that are refractory to more conservative management options [11]. A thorough history, physical exam, and noninvasive evaluation are essential to ruling out organic causes 1692 and to establish an etiology [12]. For example, many parents are not aware that their child has constipation unless specifically queried as to the frequency and caliber of the stool. Voiding dysfunction may be treated by behavior modification or pharmacological agents and rarely requires surgical intervention. A rare consequence of dysfunctional elimination is phantom urinary incontinence -an entity whereby children sense wetness when they are, in fact, dry. This phenomenon is strongly associated with obsessive compulsive disorder and responds completely to effective treatment of constipation [13]. A list of common pharmacotherapeutic agents for bladder dysfunction is provided in Table 114. Micturition into the vagina results in leakage when the child stands upright, allowing efflux of urine from the vaginal vault. Clinical findings consistent with vaginal voiding include postvoid dribbling, labial fusion, and leaning forward at an extreme angle during micturition [14]. Simple maneuvers to direct the urinary stream more accurately by separating the legs further during voiding, and waiting a few minutes after micturition to allow efflux into the toilet, usually solve the problem (Figure 114. Imaging studies are essential to define the anatomic abnormalities causing the incontinence.
This ratio of antibody to antigen (Ag*) is chosen to be sure that the number of epitopes to be presented by the labeled antigen (Ag*) always exceeds the total number of binding sites in antibody spasms muscle order flavoxate now. Consequently spasms diaphragm hiccups purchase flavoxate cheap online, unlabeled antigen (test sample) added to the sample mixture (Ab + Ag*) will compete with radiolabeled antigen (Ag*) for the limited supply of antibody kidney spasms no pain flavoxate 200 mg with amex. Even if a small amount of unlabeled antigen is added to the assay mixture (labeled antigen + antibody), it will cause decrease in the amount of radioactive antigen bound and this decrease will be proportional to the amount of unlabeled antigen added. To determine bound labeled antigen, the antigenantibody complex is precipitated to separate it from free antigen (Ag not bound to antibody). A standard curve can be generated using unlabeled antigen samples of known concentration (in place of the test sample) and from this plot, the amount of antigen in the text mixture may be precisely determined. In 1977, some years after the death of Berson, Yalow was awarded Nobel prize in recognition to her work. In one approach, the antigen can be immobilized in polystyrene or polyvinyl chloride wells and the amount of antibody in the test serum can be determined in a gamma counter by using radiolabeled anti-IgG. As this procedure requires only small amounts of sample and can be conducted in small 96-well microtiter plates, this process is best suited for determining the concentration of particular antigen. The more unlabeled antigen is present (bound), the less radioactive antigen will be bound. The system is first calibrated and a standard curve constructed with known amount of labeled antigen. Enzyme Immunoassay Enzyme-labeled conjugates were introduced first in 1966 for localization of antigen in the tissue, as an alternative for fluorescent conjugates. In 1971, enzyme-labeled antigens and antibodies were developed as serological reagents for assay of antibodies and antigens. The enzyme immunoassay is most widely used procedure in clinical serology because of its versatility, sensitivity, simplicity, cost-effectiveness and absence of radiation hazards. This reaction is visible only because the second added antibody is linked to enzymes such as horseradish peroxidase or alkaline phosphatase. The test will be positive, if the antigen has reacted with adsorbed antibodies in the first step (Refer. If the test antigen was not specific for the antibody adsorbed to the wall of the well, the test will be negative because the unbound antigen would have been washed away. A known antigen instead of antibody is adsorbed to the walls of the shallow well on the plate to see whether a serum sample contains antibodies against this antigen. Anti-antibody (antihuman globulin) tagged with an enzyme is then allowed to react with the antigenantibody complex. Finally all unbound anti-antibody is rinsed away and the correct substrate for the enzyme is added. A colored enzymatic reaction occur in the well in which bound antigen has combined with the antibody in the serum sample (Refer. In this method, the known antibody (Ab1) is first incubated in solution with a sample containing antigen. The more antigen present in the sample the less free antibody Enzyme-linked Immunosorbent Assay Enzyme-linked immunosorbent assay is so named because the technique involves the use of an immunosorbent, an adsorbing material specific for one of the components of reaction, the antigen or antibody. Variation of the test exists; for example, the reagents can be bound to tiny latex particles rather than to the surface of the microtiter plates. The antibody specific for the antigen to be detected is adsorbed to the surface of the well of the microtiter plate.
The integrity of the perineal body is evaluated spasms that cause coughing order flavoxate online, and the approximate size of all prolapsed parts is assessed muscle relaxant prescription drugs purchase flavoxate 200mg overnight delivery. A retractor or Sims speculum can be used to depress the posterior vagina to aid in visualizing the anterior vagina spasms under left breastbone generic 200 mg flavoxate with amex. After the resting examination, the patient is instructed to strain down forcefully or to cough vigorously. During this maneuver, the order of descent of the pelvic organs is noted, as is the relationship of the pelvic organs at the peak of straining. It may be possible to differentiate lateral defects, identified as detachment or effacement of the lateral vaginal sulci, from central defects, seen as midline protrusion but with preservation of the lateral sulci, by using a curved forceps placed in the anterolateral vaginal sulci directed toward the ischial spine. Bulging of the anterior vaginal wall in the midline between the forceps blades implies a midline defect; blunting or descent of the vaginal fornices on either side with straining suggests lateral paravaginal defects. Studies have shown that the physical examination technique to detect paravaginal defects is not particularly reliable or accurate. Less than two-thirds of women believed to have a paravaginal defect on physical examination were confirmed to possess the same at surgery. Thus, the clinical value of determining the location of midline, apical, and lateral paravaginal defects remains unknown. Anterior vaginal wall descent usually represents bladder descent with or without concomitant urethral hypermobility. Other uncommon conditions, such as large suburethral diverticulum or anterior vaginal cysts or myomas, can also mimic anterior vaginal prolapse. Diagnostic Tests After a careful history and physical examination, few diagnostic tests are needed to evaluate patients with anterior vaginal prolapse. A urinalysis should be performed to evaluate for urinary tract infection if the patient complains of any lower urinary tract dysfunction. Hydronephrosis occurs in a small proportion of women with prolapse; however, even if identified, it usually does not change management in women for whom surgical repair is planned [19]. If urinary incontinence is present, further diagnostic testing is indicated to determine the cause of the incontinence. Urodynamic (simple or complex), endoscopic, or radiologic assessments of filling and voiding function are generally indicated only when symptoms of mixed incontinence, pain, or voiding dysfunction are present. Even if no urologic symptoms are noted, a full-bladder cough stress test should be done with the prolapse reduced, and voiding function should be assessed to evaluate for completeness of the bladder emptying. This usually involves a timed, measured void, followed by 1252 urethral catheterization or bladder ultrasound to measure postvoid residual urine volume. If surgery to repair the prolapse is planned, it is important to check urethral function after the prolapse is repositioned. Women with severe prolapse may be paradoxically continent because of urethral kinking; when the prolapse is reduced, urethral dysfunction may be unmasked with occurrence of incontinence (occult stress incontinence) [20]. A pessary, vaginal retractor, or vaginal packing can be used to reduce the prolapse before office bladder filling or electronic urodynamic testing. If urinary leaking occurs with coughing or Valsalva maneuvers after reduction of the prolapse, the urethral sphincter is probably incompetent, even if the patient is normally continent. In this situation, the surgeon should consider adding an anti-incontinence procedure in conjunction with anterior vaginal prolapse repair [21]. If stress incontinence is not present even after reduction of the prolapse, an anti-incontinence procedure probably still decreases the rate of postoperative urinary incontinence but results in more complications, voiding dysfunction, and higher cost [21,22]. A validated, individualized computer prediction model for de novo stress incontinence after prolapse surgery is available [23]. Modifications of the technique depend on how lateral the dissection is carried, where the plicating sutures are placed, whether apical support is added, and whether additional layers (natural or synthetic grafts) are placed in the anterior vagina for extra support.
Longterm outcomes of patients undergoing creation of bowel neovagina indicate it is a durable and functionally desirable reconstructive option [46] muscle relaxant used by anesthesiologist generic 200mg flavoxate free shipping. Spontaneous voiding can occasionally be achieved with an abnormal lower urinary tract knee spasms causes buy generic flavoxate 200mg on line, provided that the pressure gradient between the bladder and distal urethra is low spasms definition discount flavoxate 200 mg free shipping. It follows, then, that even in cases where the bladder is replaced in part (intestinal cystoplasty) or entirely (neobladder), patients may still be able to empty their bladders satisfactorily. Since the advent of injectable urethral bulking agents, many patients with sphincteric incontinence owing to various causes have benefitted from antegrade and retrograde bladder neck bulking [55]. Continent reconstruction of the lower urinary tract is often desired in the face of congenital or acquired anomalies of both the outlet and bladder. The early work of Hendren, Mitrofanoff, and others has led to surgical approaches that produce both better reservoir function and a continent outlet [56]. Continent urinary diversion encompasses three interrelated but independently functioning components. These include a channel by which urine is conducted to the skin, a reservoir or pouch, and a mechanism by which continence is achieved [57]. The flap valve principle for continence dictates that a portion of the continence channel be fixed on the inner wall of the reservoir. This is the same principle by which ureteral tunneling in the bladder muscle prevents reflux during voiding. In general, a 5:1 length-to-diameter ratio of the continence structure is required. The Mitrofanoff principle of continent reconstruction describes a supple catheterizable structure (ureter, appendix, etc. The most popular form of flap valve construction for urinary continence is the use of appendix implanted into the bladder or reservoir (appendicovesicostomy). Assurance of complete bladder emptying is essential, as this type of continence channel is very effective in its ability to withstand elevated intraluminal pressures. In the noncompliant patient, pouch rupture, or upper tract injury may result from failure to empty the reservoir regularly. Urinary Tract Reconstruction and Pregnancy Future pregnancy must be kept in mind when reconstructing the genitourinary tract. Pregnancy may be complicated and requires care by both the obstetrician and urologist. Neobladder reconstruction has a good outcome, but chronic bacteriuria is frequent and occasionally requires an indwelling catheter in the third trimester [59]. Similarly, when suprapubic catheterizable continent stomas have been constructed, indwelling catheterization through the stoma during the third trimester may be required to avoid recurrent urinary tract infections from status [60]. The mode of delivery should be guided by obstetric indications, although vaginal delivery has been successful in the majority of cases. Alternatively, if the bladder neck has been reconstructed, it is usually advisable for delivery to be by cesarean section to avoid damage to the bladder neck reconstruction. The urologist should be available to the obstetric team for consultation if cesarean section is deemed necessary, especially if a bladder augmentation with bowel has been carried out, in order to avoid injury to the vascular pedicle to the bowel segment. The proximal appendix may be brought out to the umbilicus for clean intermittent catheterization (b).

The inferior gluteal artery spasms 1983 youtube purchase 200mg flavoxate otc, after originating from the internal iliac artery spasms rib cage buy discount flavoxate 200mg line, descends inferolaterally passing through the greater sciatic foramen leaving the pelvis and crossing the upper border of the sacrospinous ligament 8 spasms with cerebral palsy purchase flavoxate uk. After emerging from the sacral plexus, the inferior gluteal nerve passes close to the vessels and leaves the infrapiriform foramen crossing the upper border of the sacrospinous ligament 13. Leaving the pelvis, the inferior gluteal complex crosses the sciatic nerve posteriorly and branches inside the gluteus maximus muscle. The internal pudendal artery, after originating from the anterior branch of the internal iliac artery and accompanied by the internal pudendal vein, reaches the upper border of the ligament and leaves the infrapiriform foramen accompanied by the pudendal nerve. The sciatic nerve is situated the most laterally among the structures emerging from the infrapiriform foramen; on average, it is measured to be 25. The coccygeal branch of the inferior gluteal artery passes immediately behind the midportion of the sacrospinous ligament and pierces the sacrotuberous ligament in multiple sites. During the procedure of sacrospinous vault suspension, placing the sutures immediately medial and inferior to the ischial spine may have a potential of injury to the pudendal vessels. However, placing the sutures superior to the midportion of the ligament may cause injury to the inferior gluteal artery. The coccygeal branches of the inferior gluteal artery might be injured by any deep suture that traverses the full thickness of the ligament. Thompson has shown, by dissecting 23 female cadavers, that placing the sutures through the sacrospinous ligament 2. The hiatus is surrounded by the pubic bones anteriorly, the levator ani muscle laterally, and the perineal body and the external anal sphincter posteriorly. The levator ani muscle is always tonically contracting, keeping the urogenital hiatus closed. It closes the vagina, urethra, and rectum by compressing them against the pubic bone. The continuous contraction of the levator ani muscle keeps the hiatus closed and prevents any opening in the pelvic floor through which prolapse may occur. As long as the levator ani muscle functions normally, the pelvic floor is closed; the ligaments and fascia are under no tension. When the muscles relax or are damaged, the pelvic floor opens and the pelvic organs lie between the high abdominal pressure and the low atmospheric pressure of the introitus. Then, the organs must be held in place by the ligaments, which can sustain the load for short periods of time but eventually become damaged and fail to hold the vagina in place. This failure is due not only to acute damage of the ligaments and connective tissue but also from inability of these structures to repair themselves. The injury to the connective tissue in the pelvis is due to rupture rather than stretching [25]. The neuromuscular damage of the pelvic floor that occurs during parturition plays a major role in the etiology of prolapse; however, the repetitive loads on the pelvic floor resulting from increases in abdominal pressure also play a significant role in the development of this disorder. This results from continuous heavy lifting, chronic obstructive pulmonary disease, obesity, chronic constipation, and large fibroids or tumors; direct damage to the muscle that may result from previous pelvic surgery, spinal cord conditions and injury, and thinning of the muscle and fascia that happens with postmenopausal atrophy and attenuation; and finally the collagen status of these patients. This finding supports the hypothesized etiologic role of connective tissue disorders as a factor in the pathogenesis of these conditions [27]. The sacrospinous ligament covered by the coccygeus muscle extends from the ischial spine to the sacrum. The pudendal neurovascular structures pass beneath the sacrospinous ligament at the ischial spine. The inferior gluteal artery passes between the sciatic nerve and the sacrospinous ligament.
