Covered exstrophy and visceral sequestration with complete double bladder

Abstract

A 13-year-old boy had a complete double bladder and urethra associated with an inferior abdominal lesion, which on histological examination proved to be a colonic remnant with no communication to the underlying bowel. This entity is one of the exstrophy/epispadias complex variants known as covered exstrophy with sequestered bowel. Although 4 cases of this anomaly have been reported in the literature, to my knowledge this is the first such case with a double bladder. Excision of the lesion and the incontinent bladder was performed, and the ureter was reimplanted in the contralateral continent bladder.
