Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Suction has been initially used in endoscopic stone management for more than 25 years during PCNL, but the emergence of new devices applying suction through patented ureteroscopes, ureteral access sheaths (UAS) and ureteral catheters led to application of suction in URS/RIRS. The application of ureteral access sheath (UAS) in RIRS can improve surgical vision , reduce intrarenal pressure (IRP) ,and decrease postoperative infectious complications .
