BACKGROUND: The number of the studies made on the efficacy of flexible ureteroscopy (FURS) with ureteral access sheath (UAS) for impacted ureteral stones is limited. The aim of our study was to compare the efficacy and reliability of FURS in treatment of mid-upper impacted ureteral stones in cases where access is used or not.
