Family study of vesicoureteral reflux.
A retrospective analysis of 242 families revealed that the incidence of reflux among siblings of children with reflux was 2.2 per cent. In a prospective study of 24 families, 8 of 50 siblings (16 per cent) had reflux. Although the incidence of reflux in the prospective study is surprisingly high infections was absent in all affected siblings in whom cultures were obtained and in only 2 siblings (4 per cent) was surgical correction necessary.
