PURPOSE During the last decade it has become apparent that prenatally detected, unilateral severe hydronephrosis does not necessarily represent obstruction and may spontaneously improve or resolve postnatally. To define its natural history better we performed a long-term (mean 78 months) followup study of infants with hydronephrosis. MATERIALS AND METHODS(More)
PURPOSE We determine whether functional bladder and/or bowel disorders influence the natural history or treatment of children with primary vesicoureteral reflux. MATERIALS AND METHODS We assessed 143 children with primary vesicoureteral reflux that stopped spontaneously or was surgically corrected for functional bowel and/or bladder disorders, including(More)
PURPOSE The Snodgrass hypospadias repair is fast becoming the procedure of choice for distal hypospadias at many centers. Multiple series document excellent cosmetic outcome in conjunction with low complication rates. Modifications to the original procedure are presented, which may further limit the risk of complications. MATERIALS AND METHODS A(More)
PURPOSE We determine the outcome of severe bilateral primary ureteropelvic junction type hydronephrosis detected prenatally and managed postnatally with an initially nonoperative protocol. MATERIALS AND METHODS A total of 19 newborns (38 kidneys) with prenatally diagnosed primary grade 3 to 4 bilateral hydronephrosis were followed nonoperatively for a(More)
To store adequate volumes of urine at low safe pressures an elastic bladder wall is required. We developed 2 new techniques to measure this ability in our urodynamic laboratory: pressure specific bladder volume, which measures the bladder capacity at a given pressure, and dynamic analysis of bladder compliance. Recently, morphometric and histochemical(More)
Between 1986 and 1992, 39 boys underwent 44 pedicle flap urethroplasties as a salvage procedure using penile skin that had been relocated during prior hypospadias repair(s). All previous operations had resulted in a meatus in an unacceptable position. The salvage pedicle flap procedure used for these boys was either a Mathieu urethroplasty or an island flap(More)
PURPOSE We studied the long-term outcome of transurethral puncture of ectopic ureteroceles specifically associated with duplex systems. MATERIALS AND METHODS We retrospectively reviewed the records of patients who underwent transurethral puncture of an ectopic ureterocele. Study exclusion criteria were orthotopic, bilateral and prolapsing ureteroceles. (More)
OBJECTIVES To assess the impact of augmentation ureterocystoplasty on the success of cadaveric renal transplantation in children with dysfunctional bladders. METHODS Two patients with end-stage renal failure secondary to dysfunctional bladders (one myelodysplasia and one posterior urethral valves) underwent augmentation ureterocystoplasty prior to renal(More)
OBJECTIVE Postoperative hydrocele development is a frustrating complication of varicocele surgical repair. To avoid this complication, we began to offer percutaneous embolization as a treatment option. We present our initial experience with this technique. METHODS A retrospective review of all patients who underwent percutaneous embolization and(More)
The surgical treatment of vesicoureteral relfux can range from injection therapy to open ureteral reimplantation. Minimally invasive applications for treatment of vesicoureteral relfux include laparoscopic extravesical and intravesical ureteral reimplantation. We present our extended experience of the technique for intravesical cross-trigonal ureteral(More)
