title: Bilateral ureteral obstruction as a complication to a perforated appendix. Report of a case.
abstract: A 44-year-old man developed anuria 8 days after an operation for a perforated appendix. An intravenous pyelography showed delayed excretion on both sides with hydronephrosis, a right dilated ureter and no contrast passing to the bladder. On neither sides a ureter-catheter could be passed through the obstructions from below. By surgical intervention no ureter-catheter could be passed through the obstructions from above, and both ureters were drained with a T-tube. The benign obstruction was caused by a periappendicular abscess with inflammation and oedema of the ureteral and periureteral tissues. The condition was normalized within 7 days.
