NCT07463157
Brief Summary:
This is a prospective, interventional single blinded, randomized, single-center study designed to compare the efficacy of a ureteral access sheath with integrated suction (FANS) versus a standard ureteral access sheath (UAS) in patients undergoing ureterorenoscopy and laser lithotripsy for renal stones. The hypothesis is that the use of the FANS device improves stone-free rates and reduces postoperative infectious complications compared to the standard sheath.
Detailed Description:
Single-center, prospective, randomized, interventional, single blinded study. Participants with renal calculi undergoing ureterorenoscopy and laser lithotripsy will be randomized in a 1:1 ratio to receive either a standard ureteral access sheath (UAS) or the FANS (Flexible and Navigable Suction) sheath. Randomization will be stratified by stone characteristics, specifically stone density (≤1000 vs \>1000 HU) and stone volume (\<500 vs ≥500 mm³), as recorded on preoperative imaging, to reduce potential imbalance between study arms.
