A 63-year-old woman with a history of nephrolithiasis and long-term hemodialysis (HD) presented with abdominal pain. Abdominal computed tomography (CT) showed urinoma induced by renal forniceal rupture, and three causative calculi. No active stone growth or new stones were observed when compared with previous CT, however, fragmentation and migration of an existing stone was observed. After ureteroscopic lithotripsy and stenting with a double-J catheter, the patient made a full recovery. To the best of our knowledge, this is the first case of spontaneous renal forniceal rupture in an anuric HD patient caused by calculi. Renal forniceal rupture can occur, even in anuric HD patients.
