[Fetal megacystis--prenatal diagnosis and attempt at therapy].

Dilatations of the fetal urinary tract are suspect for obstructions. An extremely dilated bladder may also point to an innervation disorder. In the here presented case a very rare disease is the cause for the dilatation of the fetal bladder, the Megacystis-Microcolon-Hypoperistalsis-Syndrome. No mature ganglionic cells are detectable in the bladder wall histologically. Up to now eight cases have been reported, all female neonates died within the first days after birth. Our presented child - also a female - is now more than one year old, but artificial feeding is still necessary.
