PURPOSE We assessed the results of laparoscopic ureteroneocystostomy with a psoas hitch for iatrogenic lower ureteral injuries leading to a ureterovaginal fistula. MATERIALS AND METHODS Between July 2003 and November 2007, 18 patients with iatrogenic lower ureteral injuries during hysterectomy leading to ureterovaginal fistula underwent laparoscopic ureteroneocystostomy with a psoas hitch. Of...

The da Vinci robotic system has improved surgeon dexterity, ergonomics, and visualization to allow for a minimally invasive option for complex reconstructive procedures in children. Over the past decade, robot-assisted laparoscopic ureteral reimplantation (RALUR) has become a viable minimally invasive surgical option for pediatric vesicoureteral reflux (VUR). However, higher-than-expected compl...

PURPOSE We report the preliminary results of endoscopic treatment of vesicoureteral reflux in children using polyacrylate polyalcohol copolymer. MATERIAL AND METHODS We performed a prospective multicenter review of pediatric patients treated with subureteral injection of a new nonabsorbable substance. Only patients with 1 year of followup were included. RESULTS A total of 83 patients underw...

The capacity of ureteral stents to enhance the conveyance of urine from kidney to bladder is the critical function for patients that require them. The flow path in and around the stent is not a trivial one, particularly if some elements of peristalsis are present in the ureter. This paper details a numerical flow simulation for an axially symmetric stented ureter segment. The flow of urine thro...

Classic anti reflux procedures on children with a history of posterior urethral valve does not usually yield good results and often ends up with ureteral obstruction and even permanent urinary diversion. From 1981 through 1988,21 boys with history of posterior urethral valve (PUV) underwent evaluation for vesicoureteral (VU) reflux; 17 boys had VU reflux. Following valve ablation, reflux disapp...

OBJECTIVES Endoscopic injection of non-animal-stabilized hyaluronic acid/dextranomer gel is an increasingly recognized treatment option for vesicoureteral reflux. The procedure is minor compared with open surgery and, when successful, avoids the need for long-term antibiotic prophylaxis. We present data from 3 years of using non-animal-stabilized hyaluronic acid/dextranomer gel to treat childre...

OBJECTIVES The objective of this monograph is to familiarize the reader with dynamic hydrodistention classification of the ureter and Hydrodistention Implantation Technique (HIT) methodology for the endoscopic correction of vesicoureteral reflux (VUR). The indications, current success rates, complications, and potential future applications of these methods are reviewed. METHODS Hydrodistentio...

Ureteral triplication is a rare congenital anomaly of the urinary tract. Since the first description by Warny in 1870, approximately 100 known cases have been reported in the literature, often accompanied by a variety of associated anomalies in contralateral kidney. This report presents a case of ureteral triplication with contralateral duplication and vesicoureteral reflux (VUR) of the upper m...

OBJECTIVES The aim of this study was to determine sensitivity, specificity, and predictive values of sonographically demonstrated ureteral dilatation in detecting vesicoureteral reflux (VUR). METHODS Ethical approval from the Ethical Committee of Clinical Center University of Sarajevo and parental consent were obtained for this prospective study involving 120 children with history of urinary ...
