Acute abdomen: an unusual presentation of a blind-ending bifid ureter.

This case report features the unusual presentation of a blind-ending ureteric duplication (BEUD) as acute abdomen. The partially obstructed BEUD had mimicked acute appendicitis, leading to previous errors in the diagnosis and management of the case. A high index of suspicion is necessary to diagnose such a rare congenital anomaly when it presents as acute abdomen.
