Accuracy of Screening Tests for the Diagnosis of Urinary Tract Infections in Young Children

Abstract

Our findings suggest that for febrile children <36 months of age undergoing bladder catheterization for suspected UTI, pyuria will be absent in ∼20% of children who are eventually shown to have pure growth of a pathogen on a culture. This raises questions about the appropriateness of requiring pyuria for the diagnosis of UTIs.
