NCT07052188 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 210

No results posted yet for this study

Summary

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.

Conditions
