[Postnatal screening of renal developmental anomalies. Classical diagnostic methods, risk factors and routine screening].

: During a 6 years' period (2 years of control, 2 years of risk group and 2 years of routine screening) the authors examined the effect of different diagnostical methods on the frequency of detected renal developmental anomalies. The incidence of documented renal malformations was 1.1% during the use of classical diagnostical methods, 8.3% during the application of intrauterine routine and postnatal risk group screening, and 10.3% after the introduction of postnatal routine screening in 2 years' periods. The advantage of both postnatal risk group and postnatal routine screening was that the greatest part of renal anomalies could have been diagnosed before the appearance of the symptoms of urinary infection. On the basis of effectivity of postnatal routine screening and decrease of uncertainty of postnatal risk group screening authors suggested the introduction of the postnatal routine screening as general practice under our own circumstances.
