Retroperitoneoscopic ureterolithotomy in children

Abstract

Objective To present the technical details of retroperitoneoscopic ureterolithotomy in children and evaluate its clinical effects.Methods Between March 2004 and March 2007,16 children with ureteric calculus underwent retroperitoneoscopic ureterolithotomy.Nine cases were as a salvage procedure after unsuccessful ESWL,ureteroscopy or both,while the other 7 cases as a primary procedure.The stone size ranged from 1.2 cm to 2.2 tin(mean 1.62±0.35 cm)with the incarceration time from 1 month to 2 years.Results All cases underwent retroperitoneoscopic ureterolithotomy successfully,the operation time ranged from 41)to 150 minutes(mean 61.31±29.51 minutes),theblood loss ranged from 5 to 25 ml(mean 1 2.1 9±7.06 m1).Postoperative urinary leakage occurred in1 patient.but disappeared at the 3rd day after surgery.During the follow-up period of 16 cases,there was no ureteric stricture or recurrent calculus,and renal function of all these children had been improved.Conclusions Retroperitoneoscopic ureterolithotomy is a safe and effective minimally invasive procedure for children with ureteric calculus.it can partly take place of conventional open surgery.
