ABSTRACT=<p><bold>Background:</bold> Febrile urinary tract infections (FUTIs) are common among children, and are associated with a bacteraemia between 4 and 7% of cases. No data is available concerning the management of children with a bacteraemic FUTI.</p><p><bold>Objectives:</bold> To compare the antibiotic treatment (parenteral and total duration) among children with bacteraemic and non-bacteraemic FUTIs, and the mean hospital length of stay (LOS); to describe clinical, microbiological and imaging features of children with bacteraemic and non-bacteraemic FUTIs and observed management modifications when the blood culture was positive.</p><p><bold>Methods:</bold> A retrospective case-control study between 2009 and 2015 at Robert Debré's Pediatric Emergency Department (Paris, France). Children with a bacteraemic FUTI were included and matched for age and sex with two children with a non-bacteraemic FUTI.</p><p><bold>Results:</bold> We included 50 children with a bacteraemic FUTI matched to 100 children with a non-bacterameic FUTI. The mean duration of parenteral antibiotics was longer for bacteraemic children (6.7 <italic>vs</italic>. 4.0 days, <italic>p</italic> &lt; 0.001) but this difference was only significant in children &gt; 28 days-old. The mean total duration of antibiotic was similar (11.3 <italic>vs</italic>. 11.6 days, <italic>p</italic> = 0.61). The mean LOS was longer for bacteraemic children (5.1 <italic>vs</italic>. 2.0 days, <italic>p</italic> &lt; 0.001) but this difference was only significant in children &gt; 28 days-old. A positive blood culture changed the management in 66% of patients. Clinical features at presentation were comparable. Bacteraemic patients had a higher procalcitonin (<italic>p</italic> = 0.006) and C-reactive protein (<italic>p</italic> = 0.01), lower mean lymphocyte count (<italic>p</italic> &lt; 0.001).</p><p><bold>Conclusions:</bold> A bacteraemic FUTI in children induced a longer duration of parenteral antibiotic treatment, a longer hospitalization in children &gt; 28 days-old, and a modification of management for 66% of patients.</p>
