Prune-belly syndrome.
A developmental defect of the abdominal wall musculature is commonly associated with urinary tract abnormalities and cryptorchidism. Rarely, a form of prune-belly syndrome occurs in females. A characteristic finding is the presence of dimpling on the outer aspect of the knees and elbows. In mild cases, no treatment is necessary; in the most severe cases, the infant is born without renal function.
