[Screening of urologic pathology in newborns with prenatal and postnatal echography]

We compared the results, by prenatal ultrasonography, effected on 2592 foetus at the 15th-25th-35th weeks of gestation with the ones, made by postnatal ultrasonography, effected the 5th day of life on 2539 infants born from pregnancies previously monitored. We considered the obstructive and not obstructive malformations. The prenatal ultrasonography put in evidence 19 cases of urological pathology, which is 0.75%. The postnatal research established the truth of 14 cases, which is 0.55%; 7 cases underwent a precocious surgical operation. Percentage of positive false is 0.2%. The postnatal ultrasonography made evident 30 cases which can be considered pathological: 25 uropathy obstructive cases and 5 uropathy not-obstructive cases; 3 of them underwent precocious surgical operation. The result is 44 pathological cases (1.74% of infants). We also considered an heterogeneous group of non-nephro-urological anomalies (0.47%), a casual medical report of this research; in particular, 10 cases of surrenal hematoma and 1 case of neuroblastoma. The Authors remark that it's useful to complete the prenatal ultrasonographic research with another postnatal ultrasonographic research, particularly in the nephro-urological pathology; and they hope this system can be much more diffuse.
