Gap between UAS and ureteroscope predicts renal stone-free rate after flexible ureteroscopy with the fragmentation technique

Purpose To assess the effect of our new classification on surgical outcomes after flexible ureteroscopy (fURS) for kidney stones. Methods We retrospectively examined 128 patients after single renal fURS procedures performed using ureteral access sheaths (UASs) with the fragmentation technique. Based...

Summary:Purpose To assess the effect of our new classification on surgical outcomes after flexible ureteroscopy (fURS) for kidney stones. Methods We retrospectively examined 128 patients after single renal fURS procedures performed using ureteral access sheaths (UASs) with the fragmentation technique. Based on the gap (calculated by subtracting the ureteroscope diameter from the UAS diameter), enrolled patients were divided into three groups: small (
