Short treatment of urinary tract infections in children.

111 episodes of acute urinary tract infection in children without urinary tract malformations were treated by trimethoprim-sulfamethoxazole, either during 3 days or during 7-10 days. Cure rate attained almost 100%. Recurrence rates of the first infection were similar after short treatment (29.6%) and after conventional treatment (30%). It is concluded that uncomplicated urinary tract infection in ambulatory practice may be treated safely and successfully by only 3 days of an appropriate antimicrobial.
