This document provides guidelines for the diagnosis, management, and follow-up of urinary tract infections (UTIs) in children. It recommends obtaining a urine sample from infants and children presenting with unexplained fever over 38°C to test for a UTI. Clean-catch urine samples are preferred for testing, and if not possible, catheterization or suprapubic aspiration should be used. Urine samples that cannot be cultured within 4 hours should be refrigerated or preserved. Based on microscopy and culture results, treatment with oral or intravenous antibiotics is recommended depending on the child's age and location of the infection. Imaging may be used depending on risk factors, and prophylactic antibiotics should be considered for recurrent UTIs.
