Evaluation of ureteral lesions in ureterorenoscopy: impact of access sheath use

Abstract

There was a trend towards a higher risk of ureteral lesions in RIRS with a 10/12 Fr UAS compared with an endoscope alone, but when adjusting for age and gender the incidence of ureteral lesions was comparable between RIRS with and without the use of a 10/12 Fr UAS.
