RIRS with Vacuum‐Assisted Ureteral Access Sheath versus MPCNL for the Treatment of 2‐4 cm Renal Stone

Abstract

In the treatment of 2-4 cm renal stone, using V-UAS in RIRS can improve surgical efficiency with lower postoperative early pain scores. Comparing with MPCNL, its initial SFR was more depressed, and there is still a trend towards requiring more auxiliary procedures to achieve comparable final SFR.
