RESUMO
OBJECTIVE: To analyze the frequency and structure of the urinary system malformations in children born to parents exposed to radiation. MATERIAL AND METHODS: The study included 1,139 children with various congenital malformations of the urinary system, which were examined and treated in the Department of Congenital and Hereditary Diseases from 2000 to 2011. The standard clinical, laboratory, instrumental and radiographic methods were applied to verify the diagnosis. RESULTS AND CONCLUSIONS: 1. The proportion of children with congenital malformations of the urinary system among all examined in the Department of Congenital and Hereditary Diseases in the 12 years was 68.24%. 2. The congenital malformations accounted for 31.16%, small anomalies for 68.31%, and their combinations for 4.57% among all malformations of the urinary system. 3. Such complications as a secondary pyelonephritis occurred in 4.39% of cases and developed mainly in children with obstructive uropathy.
