[Prenatal diagnosis of bilateral fetal renal polycystosis].

Congenital abnormalities of the renal and urinary tract (CARUT) of the foetus constitute about 20-30% of all abnormalities. The frequency of infant mortality of genito-uretral malformations is about 10 to 100,000 lye-burts. The early and opportune antenatal diagnosis of these abnormalities by ultrasound examination of the foetus improves considerably the prognosis of children having such divergences in their renal and urinary tract. The authors represent a clinical case of antenatal diagnosis of a foetus with congenital bilateral renal polycystosis in the first half of the period of pregnancy and emphasize the importance of systematic ultrasonographic screening of the pregnant patients. A bibliographical survey of the CARUT is made together a review of the potentialities of ultrasonographic screening for diagnosing in time for due action in the presence of any abnormalities of the renal and urinary tract.
