The American Academy of Pediatrics (AAP) has issued its first update to pediatric UTI guidelines since 2011, and the changes are substantial. The revised recommendations now cover infants and children under 5, encouraging clinicians to combine symptoms, urinalysis, urine culture results, and clinical judgment when diagnosing UTIs — with evaluation recommended within 72 hours of suspected infection onset.

One of the headline changes is a push for shorter antibiotic courses. Most children should receive no more than 7 days of therapy, with lower-risk kids aged 2 and older potentially needing just 3–5 days. The guidelines also spotlight constipation and bladder-bowel dysfunction as underappreciated drivers of recurrent UTIs — a factor clinicians are now urged to actively address. Perhaps the most striking update is the removal of race as a clinical risk factor, reflecting a broader medical reckoning with race-based algorithms that may perpetuate care inequities.

Key Takeaways:

• Children aged 2–24 months with unexplained fever should be evaluated for UTI within 72 hours
• Oral antibiotics are preferred for children older than 28 days; IV-to-oral transition is encouraged once clinical improvement is observed
• Addressing constipation and bladder-bowel dysfunction is now a formal part of recurrent UTI management
• Race has been removed from risk assessment tools in favor of individualized clinical evaluation

Why it matters: With antibiotic-resistant organisms on the rise — many of which cause UTIs — these updated guidelines give clinicians a clearer, more equitable roadmap for diagnosing and treating one of the most common bacterial infections in young children.
