Cloacal exstrophy (Q46445)

Rare and complex anorectal and genitourinary malformation in which rectum, vagina and urinary tract share a common everted orifice, accompanied by an omphalocele and an imperforate anus. Exstrophy of the cloaca is a well-known malformation that includes the persistence and the exstrophy of a cloaca that receives ureters, ileum and a rudimentary hindgut. Cloacal exstrophy is a severe birth defect wherein much of the abdominal organs (the bladder and intestines) are exposed. It often causes the splitting of both male and female genitalia (specifically, the penis and clitoris respectively), and the anus is occasionally sealed.
