A 60-year-old man with a ten-year history of repeated attacks of left flank pain radiating to the left inguinal area was admitted to the hospital. An intravenous urogram and retrograde pyelogram substantiated the presence of a left ureteral herniation. Pelvic venography and arteriography proved that the ureter was not in a retroiliac vascular position. Repair of this extraperitoneal, congenital ureteral herniation required resection of the ureter and reanastomosis to the bladder. Follow-up revealed a normal left urinary tract with complete relief of symptoms.
