Description

The Prune Belly Syndrome involves a congenital defect (absence, hypoplasia) of the abdominal musculature together with urogenital disease. The disease can be classified based on the severity of the findings, which correlates with survival.


 

Gender distribution: almost always male

 

Urogenital abnormalities:

(1) renal dysplasia

(2) dilation of urinary excretory system (hydronephrosis, hydroureter, hypotonic bladder)
