Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
