[Recommendations for the diagnosis and treatment of urinary tract infection in pediatrics. Part 2: Working group associated with the Antimicrobial Committee, Chilean Society of Infectology]

Abstract

The urinary tract infection (UTI) is one of the most common bacterial infections in childhood. An adequate diagnosis is essential to be able to carry out a rational, efficient and effective treatment, however, there is great heterogeneity in diagnostic methods, specifically in the study of antimicrobial susceptibility. The aim of these recommendations is to provide tools to homogenize the diagnosis criteria, susceptibility study and antimicrobial treatment of urinary tract infection in the pediatric population, with a rational use of antibiotics approach. In the first part, the recommendations regarding diagnosis were presented, such as sampling and cut-off points, as well as microbiological considerations for susceptibility study and management of UTI in pediatrics. This second part details the management of complications, UTI in special situations, and pharmacokinetic and pharmacodynamic considerations of antimicrobials to be prescribed in UTI.
