About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

patients with complex renal stones and large or impacted ureter stones
patients who underwent laparoscopic pyelolithotomies with concomitant calyceal stone removal or ureterolithotomy using a flexible cystoscopy or not

Exclusion criteria

active infection, uncontrolled bleeding tendency, previous abdominal surgery

Treatment and study plan

Primary outcomes

the presence of residual stones

Time frame: 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 outcomes

stone numbers and sizes, surgical approach, insertion of a DJ ureteral catheter, and use of a flexible cystoscopy, etc

Time frame: 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
