Official title
A Comparative Study of Performance and Cost-effectiveness of Three Different Single-Use Flexible Ureteroscopes in the Management of Renal Stones: A Randomized Clinical Trial
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).
Detailed 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).
Interventions
- Device LithoVue™ (Boston Scientific Corporation)
Participants randomized to this arm will undergo retrograde intrarenal surgery (RIRS) for renal stone management using the LithoVue™ single-use digital flexible ureteroscope. - Device WiScope® (OTU Medical Inc. (Silicon Valley, USA))
Participants randomized to this arm will undergo retrograde intrarenal surgery (RIRS) for renal stone management using the WiScope single-use digital flexible ureteroscope. - Device Single-Use Ureterorenoscope (Scivita Medical Technology Co., Ltd.)
Participants randomized to this arm will undergo retrograde intrarenal surgery (RIRS) for renal stone management using the single-use digital flexible ureterorenoscope manufactured by Scivita Medical Technology Co., Ltd.
Primary outcome measures
- Cost-effectiveness of single-use flexible ureteroscopes [Time frame: 4 weeks postoperatively]
Secondary outcome measures (1)
- Operative Time and Postoperative Complications [Time frame: up to 4 weeks postoperatively]
