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 ] [ Designated as safety issue: No ]
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

Role of Flexible Cystoscopy in Laparoscopic Stone Surgery
The Role of Flexible Cystoscopy in Laparoscopic Stone Surgery: a Single Surgeon Experience

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.

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.
