Brief Summary

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

This study aims to evaluate how placing a stent before surgery (preoperative stenting or passive dilation) affects the success rate of retrograde intrarenal surgery (RIRS), which is performed for kidney stones. Specifically, we will examine whether stenting improves the chance of becoming stone-free after surgery and reduces the need for a second surgical procedure.
