Suction vs Conventional Ureteral Access Sheaths in Kidney Stone Surgery

Official title: Comparison of Conventional and Suction Ureteral Access Sheaths Used During Retrograde Intrarenal Surgery

Run by Antalya Health Sciences University · NCT07866209 · Data updated 2026-11-12

This study tests whether using a suction ureteral access sheath during RIRS helps adults clear stones more often and potentially reduces operative time and infections compared with a conventional sheath.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 and older with kidney stones scheduled for RIRS who can provide informed consent.

Probably not a fit

Patients whose stones are not fully cleared or who have complications unrelated to sheath type may not benefit.

What this trial studies

This observational study compares two ureteral access sheath approaches used during retrograde intrarenal surgery for kidney stones. Researchers will collect routine surgical data, including operative time, stone clearance, and any postoperative complications. Follow-up imaging will assess stone-free status. The aim is to see if the suction sheath offers advantages over the conventional sheath in real-world clinical practice.

Why it matters

Potential benefit: If successful, suction sheaths could improve stone clearance and reduce infection risks during RIRS.

How similar studies have gone: Previous studies with similar approaches have shown mixed results; this study adds real-world observational data for comparison.
