[Fetal bilateral obstructive uropathies: ultrasound findings during pregnancy and postnatal outcomes].

Purpose: to verify the association between ultrasonographic signs during gestation and post-delivery evolution in fetuses with bilateral obstructive uropathies, followed up in an expectant way.

Methods: fetuses with bilateral obstructive uropathies presenting severe oligoamnios and narrow thorax have been compared with fetuses with bilateral obstructive uropathies without those alterations, concerning the presence or absence of cysts in both kidneys, and the presence or absence of parenchymal hyperechogenicity in both kidneys. Cases of neonatal death were compared with cases of neonatal discharge from the nursery, regarding the same renal echographic aspects mentioned above, the presence of severe oligoamnios and narrow thorax.
