Abstract:
The authors describe a 31 year-old female who presented emergently with abdominal pain and was found at CT to have complete genitourinary duplication including separate urinary bladders, uteri, cervices, and vaginas, and also duplication of the rectum. No etiology for abdominal pain was identified. The patient was referred to urology for further evaluation, and an intravenous urographic study was obtained, which confirmed complete lower urinary tract duplication. The patient presented emergently 9 months later during a subsequent pregnancy for further evaluation of abdominal pain. A second CT scan was ordered to rule out appendicitis. Findings consistent with cloacal duplication were again noted. There was also dilatation of the urinary collecting systems, more prominently on the right side. A Cesarean section was performed and confirmed total genitourinary and rectal duplication.
