[Urinary tract infections and renal growth after antireflux operations in children].

An assessment has been made of renal growth and of the incidence of recurrent urinary tract infection in 116 children who had bilateral re-implantation of the ureters. Although reflux was prevented, 28% of the children continued to have infections long after the operation. The infections were mostly of the lower urinary tract whereas before the operation there was a significant incidence of acute pyelonephritis. After operation 82% of the kidneys grew normally and in 4,5% growth rate increased which is a smaller proportion than that reported in other series. In contrast 13,5% of the kidneys grew more slowly but they were usually abnormal radiologically before the operation.
