Prospective Multi-center Study Comparing Pulsed Tm:YAG Laser to Pulse Modulated Holmium Laser in the Treatment of Nephrolithiasis With FANS Access Sheaths (NCT07516106)
Prospective Multi-center Study Comparing Pulsed Tm:YAG Laser to Pulse Modulated Holmium Laser in the Treatment of Nephrolithiasis With Flexible And Navigable Ureteric Access Sheath (FANS)
🩺 Plain-English Summary (8th-Grade Level)
The purpose of this study is to compare two laser technologies that are routinely used during ureteroscopy for the treatment of kidney stones. Specifically, this study will compare a pulsed Thulium:YAG laser to a pulse-modulated Holmium:YAG laser (Moses technology) to evaluate how effective and safe they are when used to break kidney stones. Primary endpoints include stone-free rate and the zero stone-free rate at a standardized postoperative. Secondary endpoints include total operative time, lasing time (s), laser energy expended (J), efficiency (laser energy expended/stone volume; stone volume/lasing time). These endpoints aim to provide a comprehensive assessment of the clinical effectiveness and procedural efficiency of the two laser systems.
