What this trial studies

This study investigates the patient radiation dose (PRD) associated with five frequently performed endourological procedures that utilize fluoroscopy. By adjusting the frames per second (FPS) settings during these procedures, the study aims to determine the optimal PRD to minimize radiation exposure while maintaining procedural efficacy. The research is conducted across multiple centers to ensure a diverse patient population and robust data collection. The procedures under examination include ureteral stent insertion/replacement, (mini-)percutaneous nephrolithotomy, ureterorenoscopy, and extracorporeal shock wave lithotripsy.

Who should consider this trial

Good fit: Ideal candidates include patients undergoing ureteral stent insertion/replacement, ureterorenoscopy, (mini-)PCNL, or ESWL under fluoroscopic guidance.

Not a fit: Patients with bilateral cases, those undergoing diagnostic ureterorenoscopies, or procedures for upper tract urothelial carcinoma will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer endourological procedures with reduced radiation exposure for patients.

How similar studies have performed: While there have been studies on radiation exposure in medical procedures, this specific approach of adjusting FPS in endourology is relatively novel.
