A rare case of congenital mid-ureteral stricture is reported. A 17-year-old woman was admitted with sudden onset of right flank pain. Intravenous urography demonstrated bilateral small renal calculi, left hydronephrosis and a stricture of the left ureter at the level of the pelvic brim. The diagnosis was determined as congenital mid-ureteral stricture because the ureter tapered smoothly from 25 mm to 5 mm in diameter at the stenotic site. She was successfully treated by partial ureterectomy with end-to-end anastomosis. Histopathologically, no dysplasia of muscular layer was recognized.
