Ultrasound evaluation of the fetus by means of high-resolution real-time units allows a thorough survey of the fetal anatomy treatment xanax overdose order liv 52 uk, even during routine obstetric ultrasound examinations (Gearhart et al, 1995a). In these reviews, the absence of a normal fluid-filled bladder on repeated examinations suggested the diagnosis, as did a mass of echogenic tissue on the lower abdominal wall (Mirk et al, 1986; Verco et al, 1986). The main reason for the prenatal diagnosis of bladder exstrophy is so that the parents can be counseled regarding the risks and benefits and other aspects of the condition. After appropriate counseling, arrangements can be made for delivery of the baby in a specialized exstrophy center where immediate reconstruction of the exstrophy can occur. Delivery in a specialized exstrophy center allows the parents to be exposed to the expertise of multiple disciplines, including the all-important psychological support these parents need when a child with a birth defect of this magnitude is delivered. Four to 6 days before bladder closure, bilateral iliac osteotomies were performed. The continence procedure was limited to freeing the fibers from the intrasymphyseal band and wrapping this band around the urethra at the time of closure to increase outlet resistance. The initial staged approach to functional bladder closure included three separate stages: bladder and abdominal wall closure; bladder neck reconstruction and antireflux procedure; and later epispadias repair. This approach was recommended for most cases of exstrophy reconstruction beginning in the early 1970s (Cendron, 1971; Jeffs et al, 1972; Williams and Keaton, 1973). Although this procedure was successful, it has been modernized in the last 15 years to include bladder closure, abdominal wall closure, and posterior urethral closure well onto the penis in the newborn period with bilateral innominate and vertical iliac osteotomy, if indicated; epispadias repair at 6 months to 1 year of age; and bladder neck reconstruction along with antireflux procedure at age 4 to 5 years, when the child has achieved an adequate bladder capacity for bladder neck reconstruction and is motivated to participate in a postoperative voiding program (Gearhart and Jeffs, 1998). Other methods of treatment of the newborn with bladder exstrophy have been offered. Grady and Mitchell (1999) proposed combining bladder exstrophy closure with penile repair in the newborn period. Baka-Jakubiak (2000) recommended newborn exstrophy closure alone and combined bladder neck reconstruction and epispadias repair when the child reaches a satisfactory age for participation in a voiding program. Kelly (1995) has recommended a staged repair in which no osteotomy is used and a second-stage "radical soft-tissue mobilization" is performed before later urethral repair. Schrott and colleagues (1984) recommended bladder closure, ureteral reimplantation, epispadias repair, and bladder neck reconstruction in the newborn period. Lastly, Stein and coworkers (1999) recommended ureterosigmoidostomy in the newborn period with abdominal wall and bladder closure.

This was demonstrated by fluctuations of the detrusor pressure when it reached maximum during voiding and resumption of urinary stream in conjunction with a sharp fall in the detrusor pressure medicine keychain generic liv 52 200 ml free shipping. The high detrusor pressures during voiding are thought to represent variations among individual infants in the maturation process of detrusor and sphincter coordination during the first 1 to 2 years of life (Yeung et al, 1995a, 1998; Holmdahl et al, 1996; Bachelard et al, 1999; Sillen et al, 2000). In contrast, resumption of urinary flow was associated with relaxation of the external urinary sphincter and a paradoxic drop in detrusor pressure. Also, the detrusor pressure associated with the initiation of urinary flow was usually significantly lower than the maximal detrusor pressure during micturition (Pdetmax) and the Pdetmax was significantly higher than those recorded in normal adults. During the third trimester of pregnancy, the fetus is voiding at the rate of approximately 30 times every 24 hours (Goellner et al, 1981). However, immediately after birth, this drops dramatically for the first few days of life, only to increase again after the first week to reach a peak by week 2 to 4 to an average of once per hour. Subsequently this rate declines again to approximately 10 to 15 times per day between 6 to 12 months and to about 8 to 10 times per day by 2 to 3 years (Goellner et al, 1981; Yeung et al, 1995b; Holmdahl et al, 1996). This reduction in voiding frequency observed during the first few years of life appears to be related mainly to an increase in bladder volume in parallel to body growth, which is proportionately greater than simultaneous increase in urine volume production (Yeates, 1973; Koff, 1997). By the age of 12, the voiding pattern is very similar to that in an adult and usually comprises 4 to 6 voids per day. The increase in bladder volume with the growth of the child is a crucial step in the development of bladder function and urinary continence. An adequate reservoir function for urine storage is necessary to meet the increased rate of urine production and decreased voiding frequency in the growing child. A delay in the normal maturation of bladder control was attributed to certain conditions such as primary nocturnal enuresis and hence the traditional belief that all enuretics would get better with age (Nash, 1949). However, more recent studies have indicated that this is an oversimplification of what actually occurs. Even in full-term fetuses and newborns, it has been shown that micturition is modulated by higher centers. Ohel and associates (1995) showed that intrauterine micturition almost exclusively occurs while the fetus is awake rather than randomly distributed over various behavioral (sleep/arousal) states. Furthermore, it has been observed that mic- turition in a full-term fetus can be elicited by vibroacoustic stimulation, all of which indicate that the micturition reflex is probably under higher neural control even at near gestational term (Zimmer et al, 1993). Studies on normal neonates using ambulatory bladder monitoring techniques in conjunction with polysomnographic recordings have shown that even in newborns, micturition does not occur during sleep (Yeung et al, 1995b). During sleep the bladder is normally quiescent and stable with lack of facilitation of detrusor contractions, whereas during wakefulness marked detrusor overactivity is observed. Clear electroencephalographic evidence of cortical arousal or actual awakening occurs in response to bladder distention, and sleeping infants are noted to wake up before bladder activity returns and voiding occurs. However, this arousal period often may be transient, with the infant crying or moving for a brief period, micturating, and then going back to sleep without being noticed to have awakened. This wakening response to bladder distention probably involves more complicated neural pathways and higher centers than has been appreciated until now.

Casale (1991) has described a form of continent vesicostomy in which the continence mechanism is based on a flap valve created from a tubularized strip of bladder mucosa medications not covered by medicaid purchase liv 52 60 ml with mastercard. Parallel incisions 3 cm apart are made into the anterior bladder and used to create a long rectangular flap. The abdominal wall should be measured to ensure that the strip is long enough to reach the skin without tension. The muscle portion is left broad to come around without tension and provide good blood supply. The edges of this strip are mobilized until it can be tubularized along its entire length. It may be beneficial to mobilize only one edge over to the other side to avoid overlapping suture lines. Casale (1991) originally incised the mucosa transversely at the end of the intravesical strip to be tubularized; Rink and colleagues (1995b) then suggested that it could be left intact. More extensive mobilization of the side opposite that mobilized for the inner tube allows closure without overlapping suture lines, which may help avoid fistula formation and incontinence. A, Parallel incisions are made in the bladderdome,formingafull-thicknessbladderstrip. Continence rates have been good, as with most flap valves (Cain et al, 1999, 2002). Stomal stenosis remains a significant problem, 45% in the experience at Indiana University (Cain et al, 2002). Skin flaps and avoidance of tension to reach the skin may minimize this risk but not eliminate it. Advantages include avoidance of an intraperitoneal procedure and bowel anastomosis; the appendix can be reserved for use with enemas. It does use some bladder and decrease capacity, which may not be appropriate for many patients. The appendix is simple to use, suitable for most children, and associated with very good continence rates. If the appendix is not present or is to be used for antegrade colonic enemas, tapered intestinal segments provide a nice alternative. Nipple valves are the most complex continence mechanism and therefore have a longer learning curve. Continence rates approaching 85% can be expected with stapled nipple valves (Kaefer et al, 1997b; Benson and Olsson, 1998) after extensive experience.

Judging from the paucity of contemporary reports describing this lesion medicine zanaflex purchase liv 52 cheap online, it is likely that primary terminal ureteral obstruction by vascular lesions is a rare occurrence. Dourmashkin searched the literature and tabulated a series of inguinal, scrotal, and femoral herniations of the ureter (Dourmashkin, 1937). Most of these were paraperitoneal- that is, a loop of herniated ureter extended alongside a peritoneal hernial sac. In paraperitoneal ureteral hernias, the ureteral loop is always medial to the peritoneal sac. When the ureter extended into the scrotum, it was more likely to be dilated, causing upper tract obstruction. In children, herniated ureters have manifested with hydronephrosis, associated with megaureters and with persistent hydronephrosis after posterior urethral valve ablation (Jewett and Harris, 1953; Powell and Kapila, 1985; Burgu et al, 2009). Reports have been published of a sciatic hernia containing a ureter (Oyen et al, 1987; Witney-Smith et al, 2007; Tsai et al, 2008; Hsu et al, 2010), herniation between the psoas muscle and iliac vessels (Page, 1955), and lumbar triangle herniation (Cabello et al, 2008). Ureteral herniation with obstruction has been reported as a rare complication of renal transplantation (Ingber et al, 2007).

This is due to the fact that the kidney in the newborn has to become functional during the first days of life medicine for bronchitis purchase generic liv 52 from india. Indeed, the case is different in bilateral hydronephrosis when infravesical obstruction is suspected, which may require immediate diversion by a suprapubic or urethral catheter. In cases of incomplete duplication a ureteropelvic anastomosis of the upper pole ureter to the lower pole pelvis is possible, either side to side or end to side. In cases of complete duplication a standard dismembered pyeloplasty is done, depending on the function of both the upper and lower moiety and the length of the stenosis (Joseph et al, 1989). ClinicalPresentation In many countries antenatal ultrasound scans are offered at approximately 20 weeks of gestation. Of the malformations identified, urogenital anomalies are dominant and dilatations, in the form of hydronephrosis or hydroureteronephrosis, are most common. Febrile infections often are sufficiently treated with antibiotics, with only a minority of patients needing nephrostomy tube diversion in the case of concomitant finding of hydronephrosis or hydroureteronephrosis. This leads to a functional discontinuity of the muscular contractions and ultimately to insufficient emptying of the renal pelvis. Up to 50% of the affected infants have another urologic abnormality (Uson et al, 1968; Robson et al, 1976; Lebowitz and Griscom, 1977; Lebowitz and Blickman, 1983; McGrath et al, 1987). Hematuria is seen in some cases and is believed to result from disruption or rupture of mucosal vessels in the dilated pelvis (Kelalis et al, 1971; Williams and Kenawi, 1976). IndicationsforSurgery Only approximately one third of affected children will need surgical intervention (Dhillon, 1998). The widely accepted indications for surgery are an increasing anteroposterior diameter on ultrasound, low or decreasing differential renal function, breakthrough infections while on prophylactic antibiotics, or symptoms such as pain in older infants and children. SurgicalRepair When indicated, surgical intervention can be performed by open surgery or laparoscopic and robot-assisted procedures. Debate is ongoing on whether minimally invasive procedures should be conducted through the transperitoneal or retroperitoneal routes even though the majority of pediatric urologists prefer retroperitoneal access when performing an open procedure. However, no proper randomized studies have yet been published comparing either the transabdominal or the retroperitoneal laparoscopic routes. The main argument for laparoscopic transperitoneal access is that the procedure is easier and familiar anatomic landmarks assist in orientation. However, ease should not stand alone as an argument for any kind of surgical access; other variables that need to factor in are potential risk for damage to intra-abdominal organs, postoperative urine leakage, and subsequent prolonged hospital stay, all of which tip the balance toward the retroperitoneal approach. Despite a longer learning curve and a more time-consuming procedure needed for retroperitoneal access, we have preferred and advocated the use of retroperitoneoscopic pyeloplasty because the advantages seem to outweigh many of the potential difficulties encountered during the learning phase (Olsen and Jorgensen, 2004; Olsen, 2006; Olsen et al, 2007; Olsen and Rawashdeh, 2012). Chapter133 SurgeryoftheUreterinChildren 3059 Dismembered Pyeloplasty Regardless of access, the Anderson-Hynes dismembered pyeloplasty technique is the preferred procedure for most surgeons and the gold standard against which all other interventions are compared (Anderson and Hynes, 1949). The initial concerns of compromising the blood supply and innervation of the proximal ureter have since been disclaimed (Douville, 1953). In case of a long dysplastic segment of the upper ureter, complete mobilization of the kidney can bridge the distance between pelvis and ureter for several centimeters. In addition, a horizontal incision in the lower part of the pelvis can give further length and facilitate tension-free anastomosis.

Measur- ing abnormal tubular function may be possible using more sensitive measures and imaging technology medicine mound texas cheap liv 52 200 ml with mastercard. Human pathologic material has not shown large amounts of inflammation (Huang et al, 2006), except when complicated by infection (Bartoli et al, 2000; Kiratli et al, 2008). If there were a subset of patients with inflammatory changes in the face of obstruction, it would seem an important target for investigation to improve both diagnostic and therapeutic capability (Meldrum et al, 2006, 2007). The various inflammatory cascades that have been investigated postnatally are manipulable pharmacologically and this may permit important therapeutic regulation of renal injury (Cale et al, 2000). Reninsecreting renal cortical cells appear to be recruited with obstruction as well. This is clinically relevant when making decisions regarding the use of intervention either postnatally or prenatally. In the latter, the potential for reversal has great significance in determining whether the risks associated with fetal intervention are warranted. Improvement in function is also important in the expectation of response to relief of obstruction. In the fetal obstructed kidney, Glick and colleagues showed that the functional salvageability of a unilaterally obstructed kidney was dependent on the duration of obstruction and gestational age (Glick et al, 1984). A direct relationship between progression of nephronogenesis and reversibility can be demonstrated (Edouga et al, 2001; Fenghua et al, 2009). Similar observations have been made in early postnatal models, with the recognition that complete reversal of the damage is seldom achieved (Claesson et al, 1987; Chevalier et al, 1988, 1999b, 2002; Eskild-Jensen et al, 2003; Shi et al, 2004; Dissing et al, 2008; Thornhill and Chevalier, 2012). The severity of obstruction is also a critical determinant (Bussieres et al, 1993), but it is challenging to measure in any meaningful way. Biomarkers of salvageability have been developed and were first used clinically in accordance with the work of Glick and Adzick in obstructed fetal sheep (Adzick et al, 1985). From these basic parameters emerged the clinical prognostic factors currently used, with modification, in fetal obstruction (Harrison et al, 1982; Glick et al, 1985). In the face of obstruction, what is our best approach to preserve the maximal amount of renal function Even with successful surgical intervention, we are often confronted with an inexorable progression to renal failure in these children, yet it would seem reasonable to ask if we can prevent renal demise. When fetal urine approaches the character of serum, irreversible damage appears to have occurred in the developing kidney. Other markers have been explored in the fetus, including 1-microglobulin in amniotic fluid and 2-microglobulin in urine and serum (Burghard et al, 1987; Freedman et al, 1997; Nicolini and Spelzini, 2001; Craparo et al, 2007). The mechanisms of functional recovery may be similar to the mechanisms of injury, but they may also be unique and the potential may exist for enhancing recovery if these mechanisms can be understood and used. In part, the pathway of recovery includes normal developmental pathways that had been impaired because of obstruction (Chevalier et al, 1988).

This also moves the pelvic floor muscles into a more anterior position medications names discount liv 52 60 ml buy on line, thus providing more support for the anterior pelvic organs. Combined osteotomy is performed by placing the patient in the supine position, preparing and draping the lower body below the costal margins, and placing soft absorbent gauze over the exposed bladder. The pelvis is exposed from the iliac wings inferiorly to the pectineal tubercle and posteriorly to the sacroiliac joints. The periosteum and sciatic notch are carefully elevated, and a Gigli saw is used to create a transverse innominate osteotomy exiting anteriorly at a point halfway between the anterior superior and anterior inferior spines. This osteotomy is created at a slightly more cranial level than that described for a Salter osteotomy to allow placement of external fixator pins in the distal segments. In addition to the transverse osteotomy, the posterior ileum may be incised from the anterior approach in an effort to correct the deformity more completely. For this part of the osteotomy, an osteotome is used to create a closing wedge osteotomy vertically and just lateral to the sacroiliac joints. This combination osteotomy easily corrects the abnormalities in both the anterior and posterior segments of the pelvis. Two fixator pins are placed in the inferior osteotomized segment, and two are placed in the wing of the ileum superiorly. Radiographs are obtained to confirm pin placement, soft tissues are closed, and the urologic procedure is performed. At the end of the procedure, the pelvis is closed with a suture between the two pubic rami. The external fixators are then applied between the pins to hold the pelvis in a correct position. In a newborn with less than optimal amounts of cancellous bone, only one pin is placed Thus, waiting for the bladder template to grow for 6 to 12 months in the child with a small bladder is not as risky as submitting a small bladder template to closure in an inappropriate setting, resulting in dehiscence and possible future incontinence. If the bladder does not grow to sufficient size for closure after 6 to 12 months, other options include excision of the bladder and a nonrefluxing colon conduit or ureterosigmoidostomy. Osteotomy Children born with bladder exstrophy have not only an exposed bladder but a wide diastasis of the pubic rami (average 4. In addition, the larger the bladder template, the wider the resultant diastasis and the greater the need for osteotomy. The musculoskeletal function of the hip and lower extremity appears to be normal throughout childhood; however, the gait is characterized by external foot rotation, which lessens with growth as lower extremity muscle function strengthens, even if osteotomy is not performed. Several types of pelvic osteotomies have been developed to help to close the pelvic ring, decrease the stress on the abdominal wall during initial exstrophy closure, and improve the outcome of future genitourinary reconstruction. Shultz (1958) was the first, as far as we know, to describe bilateral posterior iliac osteotomy as part of a two-stage repair of bladder exstrophy. Bilateral posterior iliac osteotomy was performed, and 1 to 3 weeks later exstrophy closure was accomplished.

Struvite stones are less likely after gastrocystoplasty (Kaefer et al symptoms tuberculosis buy 120 ml liv 52 overnight delivery, 1998; Kronner et al, 1998a), likely because of decreased mucus production and acid that minimizes bacteriuria. Uric acid calculi have been noted in the bladder after gastrocystoplasty (Kaefer et al, 1998). Clearly, any foreign body will serve as a nidus for stone formation; the use of permanent sutures or staples in the urinary tract should be avoided during enterocystoplasty. Khoury and associates (1997) looked for metabolic problems in patients after augmentation and noted low urinary citrate levels in patient with and without stones. Delayed Spontaneous Bladder Perforation Another disturbing complication of augmentation cystoplasty is delayed bladder perforation. Patients with spontaneous perforation after augmentation cystoplasty are typically quite ill with abdominal pain, distention, and fever. Nausea, decreased urine output, and shoulder pain from diaphragmatic irritation have also been noted. Once bowel is reconfigured, however, it may be more prone to ischemia if high pressure does persist. The majority of patients who develop perforations after augmentation cystoplasty have had myelodysplasia. The incidence of perforation has been lower in series of patients with other diagnoses requiring bladder reconstruction (Hendren and Hendren, 1990). No matter what the cause, there is likely some field effect on the entire segment. Once a patient has sustained a spontaneous perforation, the chance of recurrence is significant (Hollensbe et al, 1992; Martinez del Castillo et al, 2005), perhaps occurring in one quarter of patients (Metcalfe et al, 2006). Consideration must eventually be given to removal of the original segment and replacement with another after repeated perforation. Early postoperative leaks from the bowel-to-bowel or bowel-to-bladder anastomoses after augmentation cystoplasty are rare and represent a technical error or problem with early healing. Delayed perforations more commonly occur within the bowel segment itself and represent a problem with long-term storage of urine within an intestinal segment. Analysis of this experience suggested that the use of sigmoid colon was the only significantly increased risk factor. Several other large series of patients with sigmoid cystoplasty have noted a low incidence of delayed perforation (Sidi et al, 1987a; Hendren and Hendren, 1990; Shekarriz et al, 2000). With inconsistent differences across multiple large series, it is unlikely that any given enteric segment is at significantly increased risk for perforation and that multiple factors influence the risk for the complication. The standard treatment of spontaneous perforation of the augmented bladder is immediate surgical repair.

Iomar, 38 years: Even in the presence of infection or asymptomatic bacteriuria, reflux is more common in younger patients (Smellie, 1991). Before removal of the suprapubic tube, 4 weeks after surgery the bladder outlet is calibrated by a urethral catheter or a urethral sound to ensure free drainage.

Giacomo, 30 years: History A thorough history is going to be invaluable in ascertaining whether and what type of bladder dysfunction is present. Churchill and colleagues proposed a classification system based on the impact of the ureterocele on the upper urinary tract, including all renal units (Churchill et al, 1992).

Pakwan, 54 years: The repetitive and consistent nature of the episodes, particularly with a nonrevealing gastrointestinal workup, should prompt consideration of a renal cause and the obtaining of an ultrasound. Notwithstanding the ethical considerations of proffering endoscopic treatment for reflux correction, endoscopic indications have a wider theoretic potential than open surgery.

Silas, 49 years: The levator ani group is positioned more posteriorly in exstrophy patients, with 68% located posterior to the rectum and 32% anterior (vs. Because the sphincter is intact, patients with superior vesical fissure went through regular toilet training and became continent without the need for a later bladder neck procedure.

Jaffar, 53 years: However, there are significant differences between the normal ranges of urine chemistries in children and adults (Battino et al, 2002; DeFoor et al, 2006).

Some of these bladders grow once the malformation is corrected; however, later bladder augmentation is often required to reach adequate capacity (Gearhart, 2002).

Tom, 63 years: The key to urinary undiversion is to understand the original pathology that led to diversion. However, unlike the penile disassembly technique, the meatus is always brought to the penoscrotal junction and later is brought distally.

Ur-Gosh, 50 years: Abdominal pressure monitoring during the uroflow can help delineate an underactive bladder condition. Assistant ports are optional, and the use of the fourth robotic arm may aid with retraction or passage of sutures (Gundeti et al, 2008).

Umul, 62 years: Secondary lateral penile curvature follows the same principles as for vertical curvature, with degloving of the penis, excision of fibrous tissue that is usually confined to the region superficial to the Buck fascia, and development of skin flaps for penile skin coverage as necessary. Also, length can be gained by placement of a dermal graft to allow lengthening of the dorsal aspect of the corpora (Woodhouse, 1986).

Josh, 46 years: Because these children are at risk for upper urinary tract deterioration, annual follow-up evaluation including renal ultrasonography is recommended as outlined in Table 142-2. The diagnosis is made after circumcision in some cases (Caldamone et al, 1999), raising the possibility that the fistula is instead an iatrogenic injury.

Thorek, 23 years: In infants, a small transverse subumbilical incision is often possible because the bladder dome is still high. The single most important determinant of long-term survival is usually the severity of the urinary tract anomaly, in particular, the degree of renal dysplasia.

Ureterocystoplasty It has been noted for years that in patients with posterior urethral valves, unilateral reflux may behave as a pop-off valve to lower intravesical pressures and protect the contralateral upper tract (Hoover and Duckett, 1982; Rittenberg et al, 1988; Kaefer et al, 1995).

Basir, 43 years: A successful renal transplant was previously thought to delay or even reverse the cystic changes, but this is not supported by more recent data (Heinz-Peer et al, 1995; Doublet et al, 1997; Kliem et al, 1997). Serum creatinine is a poor marker of glomerular filtration rate in patients with spina bifida.
