97 children, 67 girls aged 0-13 years and 30 boys aged 0-11 years, with apparent first urinary-tract infections were investigated radiologically. The intravenous pyelogram was abnormal in 15.5% of the girls and 33% of the boys and the micturating cystourethrogram was abnormal in 34% of the girls and 39% of the boys. When both examinations were combined the abnormality-rate rose to 41% in the two sexes. Accordingly, radiological investigation of the renal tract is recommended after the first proven urinary tract infection.
