The use of flexible ureteroscopy is required to improve stone-free rates in ureteroscopy for proximal ureteral stones

The main target in the treatment of proximal ureteral stones (PUS) is to provide a high stone-free rate (SFR) with low morbidity. In this study, we aimed to evaluate the need for flexible ureteroscopy (URS) by retrospectively examining one surgeon’s two-year experience of URS for PUS in a center where the flexible ureteroscope and holmium laser lithotriptor are available.
