Effect of Complete Suction-Induced Collapse of the Renal Collecting System at the End of RIRS on Early Postoperative Outcomes
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
Kangdong Sacred Heart Hospital
90 participants
Apr 20, 2026
INTERVENTIONAL
Conditions
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.

Interventions
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.
Standard Retrograde Intrarenal Surgery (RIRS) procedure is performed. At the end of the surgery, only natural drainage is allowed after stopping irrigation, without any additional active suctioning.
