New developments in the diagnosis and management of pediatric UTIs.

Urinary tract infections (UTIs) in children are common and a major source of morbidity. The incidence of UTIs in childhood is not precisely known because it is not a reportable disease, and in many cases, especially in infants, UTIs are underdiagnosed. Furthermore, the definitions and criteria for diagnosis vary considerably. This article reviews the diagnosis and work-up of UTIs in children, and presents current data reviewing the roles of radiologic imaging, surgical correction, and antibiotic prophylaxis in the setting of pediatric UTIs.
