A study of some of the methods of urinary collecon in children.

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.
