Covered exstrophy with sequestered colonic remnant

We report on a woman who presented with urinary incontinence, covered exstrophy and an abdominal mass. Radiographic studies and cystoscopy confirmed that the anterior abdominal mass did not communicate with the bladder or colon and that the gastrointestinal tract was normal. Subsequent surgical resection of the mass and Young-Dees-Leadbetter bladder neck reconstruction were performed. Histological examination of the mass revealed colonic mucosa. The etiology of the covered exstrophy and sequestered colonic remnant is discussed.
