About

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.

Enrollment: 210 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients over 18 years of age with an indication for RIRS (Retrograde Intrarenal Surgery)
