Gentamicin Irrigation and Suction Ureteral Access in Kidney Stone Surgery

Official title: The Combined Effect of Antibiotic Irrigation and Aspiration Ureteral Access Sheath on Infectious Complications in Retrograde Intrarenal Surgery: A Prospective Randomized Factorial Study

Run by Hitit University · NCT07655050 · Data updated 2026-11-12

This trial tests whether using gentamicin-containing irrigation fluid and a suction-enabled ureteral access sheath during retrograde intrarenal surgery (RIRS) can lower fever, SIRS, and sepsis after kidney stone treatment.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with kidney stones scheduled for RIRS, who have sterile urine or have had treated infection with sterile culture.

Probably not a fit

Patients with active urinary tract infection at surgery or allergy to gentamicin may not benefit and could be excluded or experience risks.

What this trial studies

This randomized, factorial trial examines two interventions added to standard RIRS: gentamicin irrigation and a suction-enabled ureteral access sheath. It aims to determine the independent and combined effects of these strategies on postoperative infectious complications after kidney stone surgery. Patients are adults with kidney stones who are scheduled for RIRS and meet safety criteria, with outcomes including fever, SIRS, sepsis, and related infectious events. The study addresses intrarenal pressure and bacterial contamination as potential drivers of postoperative infections. The design compares standard RIRS, gentamicin irrigation, suction sheath, and their combination to identify any reduction in infectious morbidity.

Why it matters

Potential benefit: If successful, this approach could reduce postoperative infections after RIRS and improve patient safety.

How similar studies have gone: There is existing interest in reducing intrarenal pressure and infection risk in RIRS, but this trial explores a novel combination of gentamicin irrigation and suction sheath.
