  "abstract": "A blind-ending bifid ureter is a rare congenital urinary tract anomaly. A 63-year-old woman with obstructive pyelonephritis due to a right ureteral stone underwent emergency urinary drainage. Retrograde pyelography demonstrated contrast opacification only up to the right upper ureter, and a guidewire failed to advance beyond the upper ureter. Percutaneous nephrostomy was therefore performed. During subsequent transurethral ureterolithotripsy, ureteroscopy revealed that the guidewire had entered a blind-ending branch, while the stone was located within the ureteral branch communicating with the renal pelvis. A blind-ending bifid ureter may mimic ureteral obstruction caused by ureteral stones and complicate transurethral urinary drainage.",
