What this Trial Is About
Researchers are evaluating 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 infections in patients with kidney stones. This study compares a suction-induced collapse technique to standard drainage after RIRS to see if this surgical change improves early recovery and patient satisfaction. The trial is a prospective randomized controlled study enrolling 90 patients aged 20 to 80 years. Participants are randomly assigned to one of two groups. The experimental group receives active suctioning through a suction ureteral access sheath (UAS) at the end of RIRS until the renal collecting system collapses visually. The control group undergoes the standard RIRS procedure, where natural drainage is allowed after stopping irrigation without active suction. This comparison aims to assess the benefits of suction-induced collapse over usual care. During the study, patients will be monitored for postoperative flank pain intensity in the recovery room and on the first day after surgery using the Numerical Rating Scale (NRS). Researchers will also track infectious complications such as fever, urinary tract infection, or sepsis within 7 days, along with total analgesic use. The study involves clinical assessments, pain scoring, and safety monitoring to evaluate early postoperative outcomes after RIRS with or without suction-induced collapse.

Screening
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
Treatment
Duration - Day of surgery
Participants undergo Retrograde Intrarenal Surgery (RIRS) where either active suctioning is applied through a suction ureteral access sheath (UAS) until the renal collecting system is collapsed or standard natural drainage is allowed after surgery.
1 surgery visit (in-person)
Post-operative Follow-up
Duration - 7 days after surgery
Participants are monitored for postoperative flank pain intensity, infectious complications, and analgesic use in the days following surgery.
1 visit within 1 hour after surgery and 1 visit approximately 24 hours after surgery, with monitoring continuing up to 7 days
