Answer

School-aged children with UTI can display the following symptoms:

  • Fever

  • Vomiting, abdominal pain

  • Flank/back pain

  • Strong-smelling urine

  • Urinary symptoms (dysuria, urgency, frequency)

  • Enuresis

  • Incontinence

Adolescents are more likely to present with typical urinary symptoms (eg, dysuria, urgency, frequency). Adolescent girls with vaginitis or a sexually transmitted infection (STI) may present with similar symptoms. In addition, adolescent girls who are diagnosed with cystitis may have a concurrent vaginitis or STI. [15]

UTI among children in this age range usually affects the lower tract, but pyelonephritis also occurs. Symptoms are similar to those in children aged 2-6 years.

Girls who have pyelonephritis in infancy or early childhood, including those with persistence of vesicoureteral reflux (VUR), usually have cystitis with UTI when they are older. They are also prone to have a recurrence during pregnancy.
