Twenty-one iatrogenic ureteral injuries (20 patients) as a result of obstetric and gynecologic operations are presented. All injuries occurred during operations for benign conditions, such as Cesarean section and transabdominal hysterectomy. Pelvic adhesions as a result of repeat Cesarean section, markedly enlarging the uterus at the time of abdominal(More)
OBJECTIVES We attempted to define predictive factors for surgery in children with antenatal diagnosis of hydronephrosis that led to postnatal diagnosis of ureteropelvic junction (UPJ) obstruction. METHODS We retrospectively evaluated our 16-yr experience (1988-2003) with 343 children (260 male and 83 female) with antenatal diagnosis of hydronephrosis that(More)
The aim of our study was to compare the accuracy of non-contrast spiral CT with ultrasound (US) for the diagnosis of ureteral calculi in the evaluation of patients with acute flank pain. 62 consecutive patients with flank pain were examined with both CT and US over a period of 9 months. All patients were prospectively defined as either positive or negative(More)
PURPOSE We determined the value of endoscopic treatment for vesicoureteral reflux associated with ureterocele. MATERIALS AND METHODS From 1984 to 2005, 109 children with a median age of 6 months underwent endoscopic ureterocele puncture. Ureterocele presented as a part of a duplex system in 97 of patients (89%) and as part of a single system in 12 (11%).(More)
Endoscopic subureteral injection of polytetrafluoroethylene was performed in 115 ureters to correct vesicoureteral reflux. We treated primary reflux in 84 single ureters, 16 duplex ureters and 4 megaureters (grade V), and secondary reflux in 11 ureters associated with neurogenic bladder, uncapped ureteroceles and failed ureteroneocystostomy. Followup(More)
Reflux nephropathy (RN) is the cause of end-stage renal failure in 3%–25% of children and 10%–15% of adults. Angiotensin-converting enzyme (ACE) converts the inactive decapeptide angiotensin I (Ang I) to the active octapeptide angiotensin II (Ang II), a potent vasoconstrictor. ACE is localized in highest concentrations on the luminal surface of endothelial(More)
PURPOSE We evaluated renal function and the incidence of urinary tract infection after successful endoscopic correction of vesicoureteral reflux. MATERIALS AND METHODS From 1988 to 2007, 169 male and 338 female patients (696 refluxing renal units) with a median age of 3.7 years underwent successful endoscopic correction of primary vesicoureteral reflux(More)
PURPOSE Children with attention deficit hyperactivity disorder disproportionately experience voiding dysfunction and persistent nocturnal enuresis due to a combination of sphincter and detrusor overactivity and nocturnal polyuria. The different treatment approaches to nocturnal enuresis often fail in these patients. Therefore, we performed a prospective(More)
OBJECTIVE To evaluate the surgical outcome of different techniques of primary hypospadias repair in a single department. METHODS We retrospectively evaluated the medical files of all patients who had undergone primary hypospadias repair at our department during the past 3 decades (1978-2009). RESULTS A total of 820 patients were divided into 3 groups.(More)
OBJECTIVE This retrospective study was undertaken to evaluate results and complications in 303 patients with symptomatic bladder outlet obstruction due to benign prostatic hyperplasia (BPH) who underwent laser prostatectomy focusing on the long-term follow-up, 57 patients had a follow-up of more than 3 years. MATERIALS AND METHODS A total of 303 patients(More)
