UTI Pathway - About UTI in Children

Urine Collection and Interpretation:

The diagnosis of UTI is made on the basis of a quantitative urine culture in addition to pyuria and bacteriuria.

A clean specimen is required for the diagnosis of UTI.

A clean catch urine is an alternative to catheter or supra-pubic collection in non-toilet trained children. This method relies on caregiver co-operation and alertness and requires the infant or young child to spend some time without a nappy.

Bag urines
are useful as a screening test only

Do not send bag urines to laboratory for culture: Bag specimens have an unacceptably high rate of contamination and may lead to unnecessary and invasive investigations. They can be used to exclude an infection but not to diagnose it.

Urine collected in the bag should be tested with a urine dipstick for leucocytes or nitrates. If the dipstick is positive, obtain a definite urine sample.

Leucocytes can be found in the urine with any febrile illness and are not specific for UTI.

Rare to find true urine infection in the absence of significant pyuria: consider asymptomatic bacteriuria or a contaminated specimen.
