Abstract:
Retrograde intrarenal surgery（RIRS）has become a first-line therapeutic option for upper urinary tract stones ≤2 cm. Although conventional ureteral access sheaths enable smooth ureteroscope insertion and reduce intrarenal pressure，but the stone-free rate（SFR）remains limited. Recently，a novel flexible and navigable suction ureteral access sheath（FANS）has improved the stone clearance efficiency，therapeutic effect，and safety of RIRS. The advent of FANS is progressively reshaping the role of RIRS within urological endoscopic surgery. This review aims to summarize the current research on FANS in the management of urolithiasis and discuss potential directions for its future development.
