<unk>  is a congenital anomaly that exists along the spectrum of the exstrophy-epispadias complex, and most notably involves protrusion of the urinary<unk>  through a defect in the abdominal wall. Its presentation is variable, often including abnormalities of the bony pelvis, pelvic floor, and genitalia. The underlying embryologic mechanism leading to<unk>  is unknown, though it is thought to be in part due to failed reinforcement of the cloacal membrane by underlying mesoderm. Exstrophy means the inversion of a hollow organ.
