Title: Laparoscopic transperitoneal ureterolithotomy for large impacted lower-ureteral calculi
Abstract: Objective To evaluate the efficacy and feasibility of laparoscopic transperitoneal ureterolithotomy for the management of large impacted lower-ureteral stones. Methods Between September 2011 and December 2012, 5 patients with complex large lower-ureteral calculi underwent transperitoneal laparoscopic ureterolithotomy, earlier attempts with ESWL (2 patients) and ureteroscopy(1 patient) had failed. Results Operation was successfully performed in all 5 cases, and no open surgery was converted in any case, the stone size range from 1.6cm to 2.5cm (mean 2.12cm), stone clearance rate is 100%. The operating time range from 75min to 120min (mean 97min), estimated blood loss 10-50ml (mean 32ml),drainage tube duration 2-5d (mean 2.8d) hospitalization time 6-14d (mean 8.6d) and follow-up period 3-14m(7.8m). No serious complications such as stone recurrence and ureterostenosis occurred during the follow-up period. Conclusions Transperitoneal laparoscopic ureterolithotomy is a safe and effective minimally invasive procedure in selected patients with large impacted lower-ureteral stones. As laparoscopic learning curve, a prudent choice is suggested in clinical practice.
