We present a case of Prune Belly Syndrome in a male fetus at 20 weeks of gestation with renal pelvis dilatation, massive bladder, mega urethral and an increase of the abdominal circumference. The complex urethral malformation-obstruction is about this sequence: urethral obstruction and massive bladder distention that causes: a) abdominal distention with subsequent atrophy or hypoplasia of abdominal muscles or Prune-Belly; b) impossibility of testicular reduction or cryptorchidism; c) megaureter by retrograde pressure or reflux from bladder; d) renal dysplasia. The triad of urinary malformations, absence or hypoplasia of abdominal muscles and cryptorchidism bilateral is knows as Prune-Belly syndrome or Eagle-Barrett syndrome.

Palabras clave : Fetal urethral obstruction; Megacystitis; Renal dysplasia; Prune-Belly syndrome; Eagle-Barrett syndrome.
