The American Academy of Pediatrics has published an updated clinical practice guideline on diagnosing and treating urinary tract infection in children aged 8 days to 5 years, replacing its 2011 guideline. It applies to children of low medical complexity across care settings. UTI is present in about 7% of febrile infants.
The guideline used GRADE and contains 8 key action statements, of which 2 are strong and 6 conditional, all based on low or very low certainty evidence, together with 4 good practice statements. They cover the medical evaluation of suspected UTI, antibiotic treatment, imaging for structural abnormalities including vesicoureteral reflux, prevention, and the assessment and treatment of bowel and bladder dysfunction. Three technical reports set out the evidence and the diagnostic criteria.
For paediatricians and GPs, this is the reference to check local pathways against, particularly for imaging after a first febrile UTI and for bowel and bladder dysfunction. Read the full key action statements before changing practice; the summary does not list them individually.
- Compare your unit's febrile infant and UTI pathway with the 2026 AAP guideline.
- Note the age range: 8 days to 5 years, low medical complexity; neonates and complex children sit outside it.
- Look for bowel and bladder dysfunction in children with UTI; the guideline addresses its assessment and treatment.
- Expect conditional, not strong, recommendations on most points; clinical judgement still carries weight.
Why it matters
Most paediatric UTI pathways still reflect the 2011 guideline, which this replaces.
Don't overread it
Most recommendations rest on low or very low certainty evidence; they are conditional for that reason.
