Retroperitoneal laparoscopic ureterolithotomy: Report of 34 cases / 中国微创外科杂志

ABSTRACT

Objective To evaluate the clinical efficacy of retroperitoneal laparoscopic ureterolithotomy.Methods A total of 34 cases(38 sides) of middle(5 sides) or upper(33 sides) ureteral calculus were treated by retroperitoneal laparoscopic ureterolithotomy.The stones were(0.8 cm?1.0 cm)~(1.5 cm?3.0 cm) in size.Twenty cases had been previously treated by unsuccessful extracorporeal shock wave lithotripsy(ESWL).Results The operation was successfully completed in 33 cases and a conversion to open surgery was required in 1 case because of extensive adhesion and blood oozing.The operating time was 45~190 min(mean,85.5 min),the intraoperative blood loss was 10~50 ml(mean,20.6 ml),and the postoperative hospitalization,3~7 d(mean,4.3 d).Postoperative recovery was uneventful.No complication was observed during a 3~24 months(mean,9.7 months) of follow-up.Conclusions Retroperitoneal laparoscopic ureterolithotomy is micro-invasive,simple to perform,and safe.
