Prune Belly Syndrome


CR – Flaccid abdominal wall with bulging flanks.

FL – Large, elongated urinary bladder with dilated prostatic urethra.


Prune belly syndrome (Eagle-Barrett syndrome) is a multisystem disorder which almost exclusively affects males. Clinically the abdominal wall lax and wrinkled due to deficient rectus abdominus muscles. Genitourinary abnormalities include undescended testes, dilated ureters, megalocystis, dilated prostatic urethra, urethral obstruction (atresia or valves) and renal dysmorphism. The bladder is often enlarged and elongated but lacks trabeculation. The wall of the bladder is thickened by replacement of normal smooth muscle with connective tissue. A similar process involving the ureters produces ureteral dilatation, although ureteral dilatation may be secondary to reflux.
