Flexible Ureterorenoscopy for Renal and Proximal Ureteral Stone in Patients with Previous Ureteral Stenting: Impact on Stone-Free Rate and Morbidity

Abstract

Technical aspects of the f-URS procedure were not modified by ureteral stenting. We found that f-URS in patients with ureteral stenting was not associated with a better SFR, except in case of ureteral location in univariate analysis. Ureteral stenting was not independently related to f-URS outcome by multivariate analysis.
