Objectives: To assess the success rate and
intraoperative complications of flexible
ureterorenoscopy (f-URS) in patients with upper urinary tract
(UUT) stones using a ureteral access sheath (UAS) without a
safety guide wire (SGW).
Patients and methods: Between April 2010 and March 2022,
464 renal units in patients with renal stones with and without
concomitant ureteral stones (UUT), underwent ureterorenoscopy
by one surgeon, and UAS was used in all of them. The primary
endpoint was the stone-free rate (SFR). SFR was defined as no
residual fragments at all. The following characteristics were
examined: age, sex, laterality, renal/ureteral stones, stone
diameter, SFR, Hounsfield unit, auxiliary procedures, double-J
stent insertion, and intraoperative complications. This study
was retrospective, with all the data recorded prospectively.
Patients with residual stones were scheduled for the 2nd RIRS.
