Brief summary

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.

Detailed description

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.

Healthy volunteers

Inclusion criteria

Exclusion criteria

* active infection, uncontrolled bleeding tendency, previous abdominal surgery

Design outcomes

Primary

Measure	Time frame	Description
the presence of residual stones	intravenous pyelogram at 12 weeks postoperatively	We judged the success when there is no residual stone in the intravenous pyelogram at 12 weeks postoperatively

Secondary

Measure	Time frame	Description
stone numbers and sizes, surgical approach, insertion of a DJ ureteral catheter, and use of a flexible cystoscopy, etc	Retrospective review of data	Preoperative evaluation included a complete history, physical examination, and imaging work-up such as X-ray or computed tomography (CT). Mean preoperative stone numbers and sizes were evaluated and we also evaluated operative information such as surgical approach, insertion of a DJ ureteral catheter, and use of a flexible cystoscopy
