EFFICACY AND SENSITIVITY OF PRENATAL AND POSTNATAL ULTRASOUND SCREENING OF CONGENITAL DEVELOPMENTAL ANOMALIES OF KIDNEYS IN SLOVAKIA.

OBJECTIVE

The aim: To compare the effectiveness and sensitivity of prenatal and postnatal diagnostics in the diagnosis of congenital malformations of the urinary system in the Slovak Republic.

PATIENTS AND METHODS

Materials and methods: Data of postnatal sonographic screening of congenital developmental malformations of the urinary system in Slovak Republic including 2017 were identified and updated using a questionnaire survey, 38,496 newborns were involved. Statistical data on the proportion of prenatal diagnosis for the years 1995, 2000, 2005, 2008 and 2013-2016 were provided from the National Register of Congenital Defects. The chi2-test and t-test were applied to assess the sensitivity differences.

RESULTS

Results: The study showed a low sensitivity of prenatal diagnosis with its maximum in 2016, reaching 32.3% and a minimum in 2005-2008 (8.0 - 8.4%). The sensitivity of postnatal diagnostics for selected years has always been a stable indicator and reaches 99.6%.

CONCLUSION

Conclusions: Available statistical data confirm that prenatal diagnostics of congenital developmental malformations of the urinary system in the Slovak Republic is not perfect. Our work underlines the importance, or we should rather say inevitability of postnatal ultrasound screening for congenital developmental anomalies in the kidneys.
