Bladder exstrophy is a birth defect that involves the low abdominal wall, urinary tract, genitals, and pelvic bones.[2] There is generally protrusion of the urinary bladder through the abdominal wall and separation of the pubic bones.[2] Urine leaks from this area.[2] In males there may be a small penis and undescended testicles.[2]
The cause is unclear.[2] Risk factors include smoking and radiation exposure during pregnancy.[2] The underlying mechanism is thought to involve an abnormally large cloacal membrane which prevents mesenchymal tissue from moving to the midline.[2] It is part of the spectrum of abnormalities known as bladder exstrophy-epispadias-cloacal exstrophy complex.[3] The diagnosis is based on examination.[2]
Prevention is by folate supplementation before pregnancy.[2] Treatment at the time of birth involves covering the area with clear plastic wrap such as saran wrap.[2] This is than followed by surgery, which may be done in one or more operations.[2] Outcomes may be complicated by urinary incontinence, hydronephrosis, urinary tract infections, or bladder cancer.[2]
Bladder exstrophy occurs in about 1 in 50,000 newborns.[2] Males are more frequently affected than females.[1] It was first described in 2000 BC.[2] The term "exstrophy" is Greek for "to turn inside out".[4]
