Brief 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.
