OBJECTIVES Pelvic immobilization constitutes a necessary component of successful bladder exstrophy closure. The efficacy of spica cast immobilization has been reported as markedly inferior to external fixation, with success rates below 25%. We reviewed our experience with spica cast immobilization following bladder closure. PATIENTS AND METHODS We(More)
OBJECTIVE To determine the current preferred injection technique(s) for endoscopic management of pediatric vesicoureteral reflux (VUR). Since the approval of dextranomer hyaluronic acid copolymer (Dx/HA) in 2001, injection methods have evolved and now include the hydrodistention implantation technique (HIT) and double HIT as well as subureteral(More)
OBJECTIVE To review the clinical manifestations and operative management of a large contemporary pediatric cohort of patients with prune-belly syndrome (PBS). METHODS PBS patients aged <21 years followed up in our pediatric urology clinic were identified by the International Classification of Diseases, Ninth Revision code (756.71). Demographics,(More)
OBJECTIVE In a group of children diagnosed with vesicoureteral reflux (VUR) we evaluated renal ultrasound findings, associated findings on renal scan, and prognostic impact on VUR resolution. METHODS Medical records were reviewed for children with primary reflux and no history of antenatal hydronephrosis who underwent an initial renal ultrasound. Abnormal(More)
PURPOSE Improved identification of children with vesicoureteral reflux at risk for recurrent febrile urinary tract infection may impact management decisions. We hypothesized that reflux occurring earlier during bladder filling increases the duration of exposure of the kidneys to bacteria, and, therefore, increases the risk of pyelonephritis. MATERIALS AND(More)
PURPOSE The vesicoureteral reflux index is a novel tool designed to predict spontaneous reflux resolution in infants younger than 2 years. We performed a multi-institutional validation study to confirm the discriminatory power of the vesicoureteral reflux index to predict the vesicoureteral reflux resolution rate in young children. MATERIALS AND METHODS(More)
INTRODUCTION AND OBJECTIVE Factors influencing the decision to surgically correct vesicoureteral reflux (VUR) include risk of breakthrough febrile urinary tract infection (fUTI) or renal scarring, and decreased likelihood of spontaneous resolution. Improved identification of children at risk for recurrent fUTI may impact management decisions, and allow for(More)
PURPOSE Ureteral stricture is a rare cause of hydronephrosis in children and is often misdiagnosed on ultrasound (US) and diuretic renal scintigraphy (DRS), requiring intraoperative diagnosis. We evaluated ureteral strictures diagnosed by magnetic resonance urography (MRU) at our institution. MATERIALS AND METHODS Children with ureteral stricture who(More)
Endoscopic management of vesicoureteral reflux with dextranomer/hyaluronic copolymer (Deflux(®), Oceana Therapeutics, Inc., Edison, NJ, USA) has gained widespread acceptance with increasing success rates and minimal morbidity. Formation of a pseudocapsule and calcification are known histologic changes at the injection site. Postoperative ureteral(More)
INTRODUCTION AND OBJECTIVE Current AUA guidelines recommend voiding cystourethrogram (VCUG) following endoscopic treatment of vesicoureteral reflux (VUR). We evaluated the clinical and radiographic outcomes of children undergoing Double HIT (hydrodistention implantation technique) for primary VUR to determine success rates and the necessity of postoperative(More)
