UTI IMAGING Given the potentially large benefit of detecting correctible malformations for a small number of children and the low risk of harm, we suggest RBUS for the following children: -Children younger than two years of age with a first febrile UTI -Children of any age with recurrent febrile UTIs -Children of any age with a UTI who have a family history of renal or urologic disease, poor growth, or hypertension -Children who do not respond as expected to appropriate antimicrobial therapy
