[Incidence of renal agenesis in the Czech Republic from 1961 to 1995].

During the period between 1961 and 1995 the incidence of renal agenesis in the Czech Republic was investigated. From a consecutive series of 5,137,907 births in the Czech Republic in 1961-1995 915 cases of renal agenesis were diagnosed, incl. 859 in born infants and 56 cases were diagnosed prenatally and the pregnancies were terminated. The mean incidence of renal agenesis in born infants during the follow up period was 1.66 per 10,000 liveborn infants, after adding the results of prenatal diagnosis the mean incidence was 2.02 per 10,000 liveborn infants. The authors investigated also the prenatal diagnosis of renal agenesis in the Czech Republic. The rate of diagnosis of renal agenesis was on average in 1988-95 in the Czech Republic more than 26% detected cases.
