| Abstract: | Deterioration of the upper urinary tract is exceptional in children on clean intermittent catheterisation for neuropathic incontinence and is found only in those with pre-existing renal damage. This report describes a bacteriological study of 24 children, of whom 10 had renal damage and 14 did not have renal damage before clean intermittent catheterisation began. Boric acid was added as a preservative to samples of urine in preference to the use of dip-slides because it preserves pus cells as well as bacteria. The incidence of bacteriuria in the two groups was similar (78% of samples from those with, and 72% of samples from those without, pre-existing renal damage). The groups differed in that the urine of children in the group with pre-existing renal damage yielded organisms other than Escherichia coli more than twice as often as did the urine of those children without renal damage. Moreover, the children with pre-existing renal damage were more likely to have fever with urinary tract infection and some of them showed frequent changes of organisms in the urine. Whatever organism was present, however, children in the group with renal damage more often had heavy pyuria. |
