[Antenatally determined nephro-urological anomalies: correctness of diagnosis and influence on management]

On the basis of the experience of 52 antenatal diagnoses of foetal urinary tract abnormalities we discuss the influence of these diagnoses on antenatal and postnatal management. A correct diagnosis was established in only 34 of the 52 cases (65%). Therefore, in utero intervention should be used with utmost restrictiveness. Moreover, the antenatal diagnosis is usually not made in the first half of the pregnancy (which most authors consider necessary) and the benefits of prenatal intervention are not yet established. The data emphasize the importance of a thorough postnatal investigation and, necessary, early treatment before severe infections may occur. Antenatal ultrasound can make an important contribution to the prevention of kidney damage.
