چکیده

OBJECTIVE This study aims to demonstrate a novel laparoscopic technique of tapering megaureter without disrupting the blood supply and disconnecting the ureter. MATERIALS AND METHODS Eight cases of primary obstructive megaureter in the age group of 14-22 years underwent laparoscopic extravesical ureteric reimplantation between August 2011 and July 2015 using our novel technique. Five patients had obstruction on left side and three on right side. Follow-up ultrasonography at 1 month and 3 months, voiding cystourethrogram (VCUG) at 3 months and intravenous urogram (IVU) at 6 months was obtained to assess the development of reflux and to look for adequate drainage of the obstructive ureter. RESULTS Average age of the patients at the time of surgery was 18.5 years. Mean operating time was 95 min. Mean blood loss of 20 ml. VCUG done after 3 months showed no reflux in all cases. IVU done after six months showed no obstruction and complete drainage of dye. CONCLUSION Our technique of tapering obstructed megaureter over a preplaced ureteral dilator is time saving and also helps in preserving blood supply to lower ureter. As a result, ureteric anastomotic stricture rate is very low. It is easily reproducible in the open as well as by robotic.

Totally laparoscopic ureteroneocystostomy with intracorporeal tailoring for primary obstructive megaureter

Laparoscopic procedures have usually been employed as an alternative to open surgery for the management of several urologic problems. Laparoscopic ureteroneocystostomy is rarely reported despite the description of different techniques. Ramalingam et al. described a 3case series of successful laparoscopic Boari flap ureteral reimplantations. Gao el al. also described a 3-case series of laparosco...

Vesicoscopic Ureteral Reimplantation: A Minimally Invasive Technique for the Definitive Repair of Vesicoureteral Reflux

The surgical treatment of vesicoureteral relfux can range from injection therapy to open ureteral reimplantation. Minimally invasive applications for treatment of vesicoureteral relfux include laparoscopic extravesical and intravesical ureteral reimplantation. We present our extended experience of the technique for intravesical cross-trigonal ureteral reimplantation for vesicoureteral relux.
