Ureteroscope Caliber and Surgeon Stress

This study aims to compare the efficacy, success rates, and stone-free rates of endoscopic ureteral stone treatment performed using two different sizes of ureteroscopes. Additionally, the psychological stress experienced by the surgeon will be evaluated immediately before and immediately after the procedure using the six-item short-form of the State Scale of the Spielberger State-Trait Anxiety Inventory (STAI). The findings will provide insight into the impact of ureteroscope size on procedural outcomes and surgeon stress levels, contributing to the optimization of ureteroscopic stone treatment.
