Effect of Complete Suction-Induced Collapse of Renal Collecting System at End of RIRS on Early Postoperative Outcomes

NIH ClinicalTrials.gov registered a new randomized controlled trial (NCT07535281) examining the effect of complete suction-induced collapse of the renal collecting system at the end of retrograde intrarenal surgery (RIRS) on early postoperative outcomes in patients with kidney stones. The study will compare experimental group (suction-induced collapse) versus control group (standard drainage) to evaluate differences in postoperative pain and infection rates.

For urology departments and clinical investigators conducting RIRS procedures, this trial registration signals ongoing research into surgical technique modifications that may improve patient recovery. Kidney stone patients may benefit from discussing this trial with their urologists if they are candidates for RIRS. No compliance obligations are created by this clinical trial registration.
