PURPOSE Factors influencing outcomes of dextranomer/hyaluronic acid injection for vesicoureteral reflux remain poorly defined. We performed multivariate analysis of the experience of 1 surgeon (WS). MATERIALS AND METHODS The study group contained 168 patients and 259 refluxing units. Goal of injection was coaptation of the orifice with creation of a(More)
AIM AND BACKGROUND Posttransplant vesicoureteral reflux (VUR) is a common urologic complication after renal transplantation, although its management is controversial. The treatment of choice is open surgical revision ureteral reimplantation with significant morbidity. Recently, endoscopic correction by using nonanimal dextranomer/hyaluronic acid copolymer(More)
OBJECTIVES To investigate the urodynamic profiles of adults with primary nocturnal enuresis (PNE) and the association of the urodynamic profile findings with the efficacy of desmopressin and/or tolterodine pharmacotherapy. At least 2% of adults are enuretic during the night. The diagnostic and treatment approach for PNE is empirically the same in children(More)
PURPOSE Traditional treatment of dysfunctional voiding in children with urinary retention involves retraining the pelvic floor muscles using biofeedback. Alpha-blockers are reported to also be effective in children with urinary retention and dysfunctional voiding. We compared the efficacy of biofeedback and alpha-blockers for dysfunctional voiding and(More)
OBJECTIVE To describe the topography of the perineal nerves from their pudendal origin to their course into the male genitalia, with specific attention on the course of the perineal nerve along the ventral penis, including branches into bulbospongiosus muscle and corpus spongiosum. MATERIALS AND METHODS The study comprised 18 normal human fetal penile(More)
PURPOSE The distribution of neuronal (n) and inducible (i) nitric oxide synthase (NOS) may have a role in the maintenance of normal urethral spongiosum and during the development of spongiofibrosis in urethral stricture disease. MATERIALS AND METHODS Eight normal and 33 strictured human bulbar urethras were studied by histological and immunohistochemical(More)
PURPOSE We report outcomes from tubularized incised plate repair of mid shaft and proximal hypospadias by a single surgeon. MATERIALS AND METHODS Chart review of all patients undergoing mid shaft and proximal hypospadias was performed. Those with tubularized incised plate were divided into 2 groups for mid shaft and proximal repairs. Group 1 underwent(More)
INTRODUCTION Extracorporeal shock wave lithotripsy (ESWL) is a well-known and successful treatment modality. In addition, it can be used in premature infants. ESWL is used to treat kidney and ureter stones in children. However, although it is a preferred noninvasive treatment in that setting, there is debate about its long-term effects on growing kidneys in(More)
PURPOSE The mechanism of human erection requires the coordination of an intact neuronal system that includes the cavernous, perineal, and dorsal nerves of the penis. We defined the communication of these 3 nerves that travel under the pubic arch using specific neuronal immunohistochemical staining and 3-dimensional reconstruction imaging technique. (More)
OBJECTIVE To review our 11-year experience and identify the mechanisms responsible for the failure of endoscopic injection for vesico-ureteric reflux (VUR) with three different injectable agents, based on the location of the ureteric orifice on endoscopy. PATIENTS AND METHODS We retrospectively reviewed the charts and endoscopic video-photographs of 46(More)
