UTI Pathway - Acute Management

1. Infants < 3 months are at risk of serious secondary infection, including septicaemia and meningitis.  Refer to Children Assessment Unit for a septic workup prior to treatment with parenteral antibiotics.

2. Children 3 to 6 months careful consideration of admission required.

3. Children > 6 months (without complicating factors - poor stream, flank mass, known structural abnormalities) can be treated with oral antibiotics

  • Oral antibiotics ( in order of preference)
    • Augmentin 15 to 25 mg/kg three times daily (45 to 75 mg/kg/day) (maximum 500mg per dose)
    • Sulfamethoxazole 200 mg and Trimethoprim 40 mg per 5ml Oral Suspension (Cotrimoxazole) 0.5ml syrup/kg twice daily (maximum dose 20ml BD)
    • Cefaclor - 125 mg/5ml - 10mg/kg/dose TDS (maximum  500mg TDS) (maximum 500mg/dose)

Antibotic choice should be rationalised once sensitivities known.


  • UTI associated with sepsis or bacteremia
  • Concern regarding obstructive uropathy
  • Failure to respond to antibiotics within 48 hours
  • Associated impaired renal function
  • Infection with non-E.coli organisms
