Abstract
Three methods of urine collection used currently in the diagnosis of urinary tract infection in children were studied. One hundred and fifty-two hospital patients were investigated: 92 by clean-catch method, 32 by the adhesive plastic bag technique, and 28 by suprapubic bladder aspiration. Results indicate that in the great majority of children a satisfactory diagnosis can be made on bacteriological grounds by the examination of specimens passed naturally and collected with care. In a minority of cases further investigation by such means as bladder aspiration may be indicated and this gives conclusive results.
