title: [Febrile urinary tract infection in infants: diagnostic strategy].
abstract: The diagnosis of febrile urinary tract infection in young children is difficult. Its prevalence is about 7.5 % but varies from 2 to 20 % according to the sex and age of the child. Except fever higher than 39°C for at least 48 h, no other anamnestic signs or from the clinical examination change significantly the probability of having a urinary tract infection or not. The most appropriate method of urine collection should be proposed to children clinically suspected of urinary tract infection, to avoid contamination and allow a proper diagnosis. Rapid tests (such as dipstick tests and microscopy) are useful to improve the likelihood of the diagnosis. This review focuses on the usefulness of anamnestic signs and clinical data, the way to collect urine and the performance of rapid diagnostic tests to increase or decrease the likelihood of acute urinary tract infection in children less than two years of age.
