title: Ureteral stenosis secondary to common iliac aneurysm: a case report and review of the literature in Japan.
abstract: A case of right ureteral obstruction secondary to right common iliac aneurysm presenting as right hydronephrosis is reported and the literature is reviewed. A 66-year-old man was admitted to our hospital with lower abdominal pain and was treated by bypass operation with artificial vessel and uretero-ureterostomy of right ureter under the diagnosis of right ureteral stenosis secondary to right iliac aneurysm. Histological examination showed arteriosclerotic aneurysm and a fibrillary inflammatory change in peri-ureteral tissue without any hemosiderin-laden macrophages. Intravenous pyelography showed improvement of right hydronephrosis 45 days after operation. To date 11 cases including our case have been reported in Japan, 10 in males and the other in a female. Initial symptoms were either lumbago or an abdominal mass with palpitation in many cases. The treatment was by resection of aneurysm with bypass grafting or ureterolysis.
