[Prune-belly syndrome prenatal diagnosis].

We present the ultrasonographic diagnosis at the 19th gestational week in a case of Prune-belly syndrome which consists in abdominal wall distension with deficiency of the abdominal wall musculature, urinary tract abnormalities (specially mega bladder), and in males, cryptorchidism. The pathologic examination found the patient devoid of striated muscles anterior abdominal wall, hypertrophy of the urinary bladder, and urethral atresia. The Prune-belly is accessible to antenatal diagnosis and the variable prognosis does not always justify abortion.
