title: [A case of true ureteral diverticulum].
abstract: A 31-year-old man was presented with an asymptomatic repeated gross hematuria. A drip infusion pyelography (DIP) revealed a pouch with a stone in the left lower ureter. 29 months later, he was re-hospitalized for left flank pain. Urinalysis revealed 10 to 19 RBC and 20-29 WBC/HPF. A DIP demonstrated left mild hydronephrosis due to the ureteral stenosis just proximal to the stone filled-ureteral pouch. He underwent partial ureterectomy. Histologic examination revealed the true ureteral diverticulum with all the layers of a ureteral wall. True ureteral diverticulum is a rare congenital anomaly. To our knowledge, this is the 3rd case in the Japanese literature.
