Recomendaciones sobre diagnóstico, manejo y estudio de la infección del tracto urinario en pediatría. Rama de Nefrología de la Sociedad Chilena de Pediatría. Parte 1

Urinary tract infection (UTI) is one of the most frequent bacterial infection in pediatrics. However, its diagnosis and management can be complicated due to the nonspecific clinical presentation, the difficulty of exams interpretation, especially in younger children, and an uncertain prognosis regarding renal damage. In recent years, significant worldwide change has come in treatment, diagnosis, and images studies, we have decided to update the current recommendations on UTI management published by the Pediatric Nephrology branch of Chilean Pediatrics Society in previous years. The purpose of these recommendations is to reduce the variability of clinical practice in management of UTI in our pediatric population, favoring diagnostic and therapeutic interventions in the most appropriate way, improving detection and management of structural pathology and other risk factors of renal damage, avoiding unnecessary actions in children with low risk. This first part includes diagnosis and treatment recommendations of urinary tract infection in pediatric age. In the second part the study, prevention and monitoring of urinary tract in pediatric age is detailed.
