    ABSTRACT: Oligohydramnios (OA) is nowadays regarded as one of the best markers of renal function (RF) impairment in bladder outlet obstruction (BOO) detected in utero. As such, its onset is usually early and progressive because of decline in fetal urine production. A series of acute OA complicating pregnancies with BOO has never been reported. Over a 7-year period, 5 fetuses with in utero suspicion of BOO exhibited an abrupt decrease of amniotic fluid after the 30th week of gestation. All fetuses were delivered by cesarean section: diagnosis was posterior urethral valves in 3 cases, urethral atresia in 1, and prune-belly syndrome in 1. Urologic work-up demonstrated a unilateral vesicoureteral reflux dysplasia (VURD syndrome) in all 5 fetuses. RF at 1 year was normal in 4 fetuses and impaired in 1. Besides obstetrical reasons, OA may also have acute onset occurring in the presence of anomalies of the urinary tract; although diagnosis is almost always BOO, functional and anatomical characteristics of the urinary tract are those of VURD syndrome with a non-functioning, refluxing renal unit. The associated acute OA/VURD syndrome may represent a milder expression of a pop-off mechanism advocated in this syndrome with a more favorable prognosis than progressive OA detected early in pregnancy.

    ABSTRACT: Followup of total urogenital mobilization for persistent urogenital sinus is well established anatomically and functionally. Nevertheless, studies comparing bladder function in different subsets of patients with urogenital sinus, such as congenital adrenal hyperplasia and cloaca, are scant. We reviewed the records of patients with congenital adrenal hyperplasia and cloaca who underwent total urogenital mobilization and urodynamics in the last 10 years. Those with a short urogenital sinus (less than 2.5 cm) not requiring an abdominal approach and without spinal dysraphism were selected for study. Urodynamics were performed postoperatively before and after toilet training, and compared between patients with congenital adrenal hyperplasia and cloaca. Methods, definitions and units conformed to International Continence Society/International Children's Continence Society standards. For the emptying phase we defined bladder outlet obstruction as maximum detrusor pressure greater than 70 cm H(2)O and underactive detrusor as maximum detrusor pressure less than 20 cm H(2)O plus post-void residual urine greater than 25 ml. Six patients with congenital adrenal hyperplasia and 6 with cloaca met study criteria. Three patients with congenital adrenal hyperplasia and 4 with cloaca underwent urodynamics before and after toilet training at a median age of 2 (range 2 to 4) and 5 years (range 3 to 8), respectively. Urodynamics were done in 1 patient with congenital adrenal hyperplasia before toilet training, and in 2 with congenital adrenal hyperplasia and 2 with cloaca after toilet training. All patients had normal urodynamics except 1 with congenital adrenal hyperplasia and detrusor overactivity, which normalized after toilet training. In all cloaca cases urodynamics were abnormal. Before toilet training bladder outlet obstruction was found in 2 patients, detrusor underactivity was found in 1 and detrusor overactivity was found in the remaining 1. After toilet training a detrusor underactivity pattern was found in 4 patients and bladder outlet obstruction was found in 2. All patients except 1 with cloaca had post-void residual urine before and after toilet training (median 100 ml, range 25 to 200). After toilet training all patients with congenital adrenal hyperplasia became spontaneously dry and all with cloaca were placed on clean intermittent catheterization. In the long term patients with cloaca show bladder outlet obstruction or underactive/acontractile detrusor patterns, which are not noted in patients with congenital adrenal hyperplasia. Therefore, in patients with cloaca urogenital sinus length may not be as good an indicator of functional results as it is in patients with congenital adrenal hyperplasia. Whether additional rectal dissection and repositioning surgical procedures in cloaca cases may have a role in explaining such a difference remains to be clarified.

    ABSTRACT: We evaluated the efficacy of percutaneous tibial nerve stimulation for different types of pediatric lower urinary tract dysfunction. A total of 14 children with idiopathic overactive bladder, 14 with dysfunctional voiding, 5 with underactive bladder, 4 with underactive valve bladder and 7 with neurogenic bladder resistant to conventional therapy underwent percutaneous tibial nerve stimulation weekly for 12 weeks. The stimulation effect was evaluated by comparing bladder diary, flowmetry and urinalysis before and after treatment. Improved patients were followed by bladder diary and urinalysis. Followup data at 1 and 2 years were compared with those obtained after stimulation. Data were analyzed using Fisher's exact test. Symptom improvement was significantly greater in nonneurogenic than in neurogenic cases (78% vs 14%, p <0.002). Of patients 18% with underactive bladder and 50% with underactive valve bladder were unresponsive. Of 14 overactive bladder cases 12 and all 14 of dysfunctional voiding were improved (p not significant). Of improved patients 5 of 12 with overactive bladder and 12 of 14 with dysfunctional voiding were cured (p <0.01). On uroflowmetry voided volume and post-void residual urine became normal in a greater number of dysfunctional voiding than overactive bladder cases (57% vs 20% and 57% vs 25%, each p not significant). At 1 year of followup the cure rate was greater in dysfunctional voiding than in overactive bladder cases (71% vs 41%) and it remained the same at the 2-year evaluation. Chronic stimulation was necessary to maintain results in 29% of dysfunctional voiding and 50% of overactive bladder cases. Percutaneous tibial nerve stimulation is reliable and effective for nonneurogenic, refractory lower urinary tract dysfunction in children. Efficacy seems better in dysfunctional voiding than in overactive bladder cases. There is evidence that percutaneous tibial nerve stimulation should be part of the pediatric urology armamentarium when treating functional incontinence.

    ABSTRACT: Objective. To present a case of isolated ascites secondary due to urogenital abnormalities (urogenital sinus) without any other prenatal ultrasound marker. Method. A 36-year-old woman with prenatal isolated ascites delivered a female baby, weighing 2.285 g; ascites was drained at birth and the baby underwent several episodes of urinary retention prior to undergoing X-ray investigations. Results. A voiding cystourethrogram revealed a short urogenital sinus: a vesicostomy was performed. A vaginoscopy revealed double vagina with a large posterior vagina. A posterior sagittal anorectal pull-through with genitoplasty was performed at 2 years old with 1-year follow-up. Conclusions. Though rare, a urogenital abnormality is to be suspected in fetal ascites cases with negative viral tests and no cardiac anomalies. The most common ultrasound marker of such abnormalities (fluid filled cavity) may be missing because of complete drainage of urine through the tubes into peritoneum.
