Comparison of Suction and Conventional Ureteral Access Sheaths in Kidney Stone Surgery

Sponsor: Antalya Health Sciences University

View on ClinicalTrials.gov

Summary

The goal of this observational study is to compare conventional and suction (aspiration) ureteral access sheaths used during retrograde intrarenal surgery (RIRS) in adults with kidney stones. The main questions it aims to answer are: * Does the use of a suction ureteral access sheath increase the stone-free rate compared with a conventional sheath? * Does the use of a suction sheath reduce operative time and complications such as postoperative fever and infection? Researchers will compare patients treated with a conventional ureteral access sheath with patients treated with a suction ureteral access sheath during routine RIRS. Participants will: * Undergo RIRS for kidney stones as part of their routine clinical care * Have their surgical data recorded, including operative time and any complications * Attend routine follow-up visits, including imaging to assess whether stones remain

Interventions

DEVICE

Conventional Ureteral Access Sheath

A standard CE-marked ureteral access sheath without suction, placed during RIRS to provide repeated access to the kidney and facilitate irrigation outflow.

DEVICE

Suction Ureteral Access Sheath

A CE-marked ureteral access sheath connected to a negative-pressure suction system, placed during RIRS to allow continuous aspiration of irrigation fluid and stone fragments.
