title: Ureteral obstruction resulting from vascular prosthetic graft surgery.
abstract: Four cases of ureteral obstruction are described which were primarily due to compression from an overlying vascular graft and retroperitoneal fibrosis. Infection may also be causal. Excretory urography should be performed routinely after vascular prosthetic surgery to permit early diagnosis of this complication. Ultrasonography may also be helpful in certain cases.
