We retrospectively evaluated the safety and effectiveness of retrograde ureteroscopy via ileal conduit construction. Between January 2014 and December 2021, 5 patients (8 procedures) with ileal conduit construction received retrograde ureteroscopic lithotripsy with a 11/13 Fr ureteral access sheath. At postoperative 1 month, a plain computed tomography (CT) and kidney, ureter, and bladder X-ray (KUB) were performed to assess stone fragmentation and hydronephrosis. According to postoperative imaging, stone-free was defined as residual fragments of 4 mm or less on KUB and 2 mm or less on CT. The mean stone size was 11 mm (6-13 mm). The mean stone volume was 1. 51 ml (0.33-2.56 ml). The mean operative time was 91 min (60-133 min). SFR was 100% on KUB and 87.5% on CT. One procedure (12.5%) resulted in a postoperative fever greater than 38.5℃. There were no complications of grade III or higher according to the modified Clavien-Dindo classification. No exacerbation of hydronephrosis was observed on CT. Retrograde ureteroscopy with a ureteral access sheath was found to be effective for urolithiasis in patients with ileal conduit.
