The sensitivity and specificity of the 5 min postinjection radiograph during urography were studied in 131 children. The 5 min film was overall accurate in 83.2%, with a 56% sensitivity and 91.3% specificity in patients with urinary tract infection (n = 62). In cases in which the 5 min film was not diagnostic, it nevertheless raised enough suspicions to dictate additional films. It is suggested that in urinary tract infection, errors will not be made if the single 5 min postinjection film is reviewed and additional films are obtained only if parts of the urinary tract are incompletely visualized or appear questionable. Further study is necessary to explore the merits of a similar approach for pediatric urography unrelated to urinary tract infection.
