Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients admitted to our clinic with ureteral calculi and scheduled for ureteroscopic lithotripsy will be informed about the procedure, potential complications, and routine protocol by the investigator. Patients who consent to the operation will subsequently receive detailed information about the study. Those agreeing to participate will provide written informed consent.

During the ureteroscopy procedure, standard clinical protocols will be followed. The choice of ureteroscope (4.5-6 Fr or 7.5-9.5 Fr) will be made by the operating urologist based on the patient's ureteral orifice and ureteral width. The study will not influence the selection of the ureteroscope. Intraoperative parameters, including procedure duration, complications, Double-J stent placement, failure to access the stone, and basket use, will be recorded by the research team.

To assess the impact of ureteroscope size on surgical stress, the operating surgeon's stress levels will be evaluated immediately before and after the procedure using the six-item short-form of the State Scale of the Spielberger State-Trait Anxiety Inventory (STAI).

Postoperatively, all patients undergoing ureteroscopic lithotripsy will undergo a supine direct abdominal radiograph on postoperative day 1, as per routine clinical practice. Stone-free status will be determined based on this radiograph and recorded by the investigator. Throughout the study period, no modifications to standard clinical procedures will be made.
