Effect of Preop Stent Duration on SFR and Secondary Intervention in RIRS

Evaluation of the Effect of Preoperative Stenting Duration on Stone-Free Rates and the Need for Secondary Surgical Intervention in Retrograde Intrarenal Surgery

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.

Inclusion Criteria:

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

Exclusion Criteria:

• Patients under 18 or over 65 years of age
• Patients who cannot be followed up in the postoperative period
