Overview

The current study aims to compare the performance of three distinct single-use digital flexible ureteroscope types in terms of cost-effectiveness, postoperative complications, operating time, and stone-free rates (SFRs).

Description

Retrograde intrarenal surgery (RIRS) is the preferred treatment modality for renal stones measuring less than 20 millimeters (mm). Several types of flexible ureteroscopes are currently available on the market from different manufacturers. However, there is a shortage of comparative studies evaluating the performance of different single-use flexible ureteroscopes.

This study aims to compare the performance of three different single-use digital flexible ureteroscopes in terms of cost-effectiveness, postoperative complications, operative time, and stone-free rates (SFRs).

Eligibility
