The Prune Belly Syndrome combines dilation of the bladder and a laxity of t
he abdominal wall, and is of unknown etiology. The sequelae are a pulmonary
hypoplasia and a deterioration of the kidney function, which determine pro
gnosis. Via early ultrasound diagnosis, intrauterine application of a vesic
o-amniotic shunt can be performed and can improve survival rates. Inclusion
criteria for a vesico-amniotic shunt are a lack of further sonomorphologic
al abnormalities, a lack of an indication for an alteration of the kidney f
unction by ultrasound or laboratory tests, and a normal caryotype.
