Urinary tract infection: a search of evidenceOBJECTIVE: to review urinary tract infection in children taking into consideration evidence-based medicine. SOURCES OF DATA: search of Medline and Cochrane databases, comprising the period between 1996 and 2002, with the following key words: urinary infection, vesicoureteral reflux, children, adolescents, diagnosis and treatment. Cohort studies, quality assurance studies, consensus, meta-analysis studies, randomized controlled trials and audits were selected. SUMMARY OF THE FINDINGS: the studies were selected according to their methodology, relevance and clinical applicability. Some studies were selected based on the parameters proposed by the American Academy of Pediatrics in 1999 for the diagnosis and treatment of urinary tract infection in children between two months and two years of age. CONCLUSIONS: consensus statements on diagnosis and treatment of urinary infection in children and adolescents are still mostly opinion-based. Randomized multicentric controlled trials, with double-blind allocation are necessary to improve quality of diagnosis and management of pediatric urinary tract infection.
