Super-Pulsed Thulium Fiber Laser Versus Holmium:YAG Laser in Retrograde Intrarenal Surgery for Upper Ureteral and Renal Stones

Sponsor: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Summary

The holmium laser is currently considered the gold standard for lithotripsy on urinary lithiasis, whereas the super-pulsed thulium fibre laser is a relatively new technology. Through a multi-center prospective randomised clinical study that mainly aims to explore the effectiveness and safety of a super-pulsed fibre thulium laser compared to a holmium laser in the treatment of upper ureteral and renal stones (10mm\<cumulative maximum diameter ≤ 25mm) in retrograde intrarenal surgery. The research participants are assigned randomly to undergo retrograde intrarenal surgery (RIRS) either using a super-pulsed thulium fibre laser or a holmium-YAG laser with an allocation ratio of 1:1. The secondary aim of this study is to provide high-level evidence for the development of diagnostic and treatment guidelines in the field of urolithiasis, both domestically and internationally. The outcomes of the RIRS procedures are compared for the two treatment arms.
