Abstract:
Objective To compare the therapeutic effects of minimally invasive percutaneous nephrolithotomy(MPCNL) and retroperitoneal laparoscopic ureterolithotomy(RLUL) in the management of impacted upper ureteral calculi.Methods A total of 72 patients with unilateral impacted upper ureteral calculi were treated with MPCNL(n=45) or RLUL(n=27).The operation time,clearance rate of the stone,and the incidence of postoperative hyperpyrexia were statistically analyzed.Results All the operations were completed.As compared to the RLUL group,the MPCNL group had a significant shorter operation time [(43?9) minutes vs(69?17) minutes,t=-11.564,P=0.000].On the day after the operation,both the groups showed a stone clearance rate of 100%.No significant difference was detected in the rate of postoperative hyperpyrexia between the two groups [13.3%(6/45) vs 11.1%(3/27),?2=0.000,P=1.000).The patients were followed up for 1 to 24 months(mean,8 months),none of them developed ureteral stricture or recurrent stones during the period.Conclusion Both MPCNL and RLUL are safe,effective,and feasible for impacted upper ureteral calculi.
