简要总结
Authors want to investigate the usefulness of flexible cystoscopy in performing laparoscopic pyelolithotomies and ureterolithotomies by comparing operative results of a single surgeon's experience.
详细描述
Previous trials to increase stone clearance rates have been recently reached using flexible equipment in laparoscopic surgery, however, it is not clear whether using flexible equipment is really helpful in performing pyelolithotomies and the clearance rates using flexible equipment varies 71% to 100%. Therefore, authors plan to investigate the usefulness of flexible cystoscopy in performing laparoscopic pyelolithotomies and ureterolithotomies by comparing operative results of a single surgeon's experience.

结局指标
主要结局
the presence of residual stones
时间窗: intravenous pyelogram at 12 weeks postoperatively
We judged the success when there is no residual stone in the intravenous pyelogram at 12 weeks postoperatively
次要结局
- stone numbers and sizes, surgical approach, insertion of a DJ ureteral catheter, and use of a flexible cystoscopy, etc(Retrospective review of data)
