文摘

A bifid ureter with a distal blind-ending branch is a rare congenital anomaly. Most patients are asymptomatic; only patients with complications, such as infection, vesicoureteral reflux, or stone formation, present symptoms.We describe the case of a patient with urinary stone located in the distal blind-ending branch of a bifid ureter diagnosed during transurethral lithotripsy. Preoperative noncontrast-enhanced computed tomography did not reveal a stone in the distal blind-ending branch of the bifid ureter, but a rigid ureteroscope did; however, it could not reach the stone. Therefore, the stone was extracted using a basket catheter under a flexible ureteroscope.
