The authors use a regional birth defect registry computerized since 1976 January 1st. They describe the incidence of urinary tract defects, excluding renal dysplasias. Their classification shares this group of malformations in 3 parts: those included in a multiple defects association, identified or not, those associated with renal defects, and the isolated urinary tract defects.
