MATERIAL AND METHODS A 12-year old girl presented with a history of central abdominal pain and UTI. Ultrasound showed severe hydronephrosis (APD-39 mm) with marked calyceal dilatation and an intrarenal pelvis. DMSA confirmed 18 % function. RESULTS Transperitoneal laparoscopy was performed using two-3 mm working ports and a 5 mm transumbili- cal port for the telescope. A posterior facing high PUJ in a malrotated kidney was noted. Ureter and renal pelvis were exposed by reflecting the ascending colon. Proximal ureteric end was transfixed, ligated and divided. An anterior 2 cm vertical incision over the thinned out lower pole calyx was made using scissors and ureter spatulated. Uretero-caliceal anastomosis was completed in a running fashion using 6/0 Monocryl. The calyceal urothelium was clearly identified during the anastomosis. Standard 4.7Fr JJ stent (removed in 6-weeks) and Foleys urethral catheter were left in situ. Patient was discharged in 48 hours following removal of catheter. CONCLUSIONS Laparoscopic uretro-calycostomy is a feasible, safe and useful technique in suitable or unusual PUJ anatomy. It can be achieved with just two-3 mm working instruments. The primary port through the natural umbilical scar in addition achieves good cosmesis. VD-2 (VS without presentation) ENDO-URETEROTOMY WITH CUTTING-BALLOON IN PRIMARY OBSTRUCTIVE MEGAURETER Alberto PARENTE, Ruben ORTIZ, Laura BURGOS and Jose Maria ANGULO Gregorio Marañon University Hospital, Pediatric Urology, Madrid, SPAIN PURPOSE In the last years, balloon dilatation has become a safe and valid alternative in the treatment of primary obstructive megaureter (POM). In this video we will demonstrate endo-ureterotomy using a cutting balloon for POM in case high-pressure balloon dilatation fails.
