Urinary tract infection in children: diagnosis and treatment.

Urinary tract infection (UTI) is a fairly frequent occurrence in children. Diagnosis should be made quickly and accurately by Gram staining and culture of an uncontaminated urine specimen. A first, uncomplicated UTI should be treated with sulfonamides or nitrofurantoin. Careful follow-up is necessary because of the high risk of recurrence. Sensitivity studies and specific antimicrobial therapy are indicated in any patient with recurrence and in patients with anatomic urinary tract abnormalities. Long-term prophylaxis may be needed.
