Flexible negative pressure suction ureteral access sheath combined with ureteroscopy in the treatment of upper urinary tract calculi: A meta-analysis.

ABSTRACT:

Background

Upper urinary tract stones are common diseases in urology. Ureteroscopic lithotripsy is one of the main methods for the treatment of upper urinary tract stones. With the rise of flexible urinary tract examination (F-UAS), it makes surgery safer and more effective. This study aims to compare the safety and effectiveness of flexible ureteral access sheath and traditional ureteral access sheath when used with ureteroscopic lithotripsy for treating upper urinary tract stones.

Methods

A systematic search was conducted on PubMed, Embase, cochrane library, scopus, and web of science databases for studies that evaluated the use of F-UAS in treating upper urinary tract stones. The outcome measures assessed in this study included operation time, immediate stone-free rate (S
