Prenatal detection of internal urinary system's anomalies. A registry-based study.
Prenatal diagnosis performed by ultrasound scan is now a routine part of antenatal care in our region. How many fetal anomalies are actually detected by this procedure? We have used our registry of congenital malformations to answer this question regarding to Internal Urinary System (IUS) anomalies. The mean time of detection of IUS anomalies was 29 weeks of pregnancy (12-39). The sensitivity of prenatal diagnosis of IUS anomalies by ultrasonographic examination was 59.3% for isolated malformations (fetuses with only one anomaly) and 46.0% for multiple malformed children with IUS anomalies. For all cases of IUS anomalies the percentage of prenatal detection was 56.0. Termination of pregnancy was performed in 9.4% of the cases.
