Impact of ureteral access sheath force of insertion on ureteral trauma: In vivo preliminary study with 7 patients.

Abstract

BACKDROUND: Ureteral access sheaths (UASs) are commonly used in retrograde intra-renal surgery (RIRS). Despite their advantages, there is a risk of ureteral trauma during their placement and subsequent stricture following surgery. The aim of this study was to evaluate the UAS force of insertion (F01) during placement and its impact on ureteral trauma.
