We conducted a prospective randomized study to evaluate the efficacy of a single daily dose of 4 mg/kg of trimethoprim coupled with 17.5 mg/kg of sulphadiazine for three (group 1) or 10 days (group 2) in the treatment of uncomplicated urinary tract infections in children. Forty patients (nine boys and 31 girls) aged 2.5-18 years, presenting with a urinary tract infection were allocated to one of the two groups. Patients were seen three, 10, and > or = 38 days after the initiation of treatment. Control urine cultures were negative in all patients at days 3 and 10. Two patients in group 1 and one patient in group 2 suffered a relapse within a month. Single doses of trimethoprim/sulphadiazine for three or 10 days are effective in the treatment of uncomplicated urinary tract infections in children.
