Effect of Complete Suction-Induced Collapse of the Renal Collecting System at the End of Retrograde Intrarenal Surgery on Early Postoperative Outcomes: A Prospective Randomized Study
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
The purpose of this study is to evaluate whether actively suctioning the renal collecting system to induce a collapse state at the end of retrograde intrarenal surgery (RIRS) can reduce postoperative pain and infection in patients with kidney stones. Participants will be randomly assigned to either the experimental group (suction-induced collapse) or the control group (standard drainage). The study aims to determine if this simple surgical modification can improve early recovery outcomes and patient satisfaction.

Treatments
Experimental: Suction-induced collapse group
At the end of Retrograde Intrarenal Surgery (RIRS), active suctioning is performed through a suction ureteral access sheath (UAS) until the renal collecting system is visually confirmed to be collapsed.
Active_comparator: Control group
Standard RIRS procedure is performed. At the end of the surgery, only natural drainage is allowed after stopping irrigation, without additional active suctioning.
