Urinary tract infections (UTIs) are among the most common bacterial diseases in childhood affecting approximately 3-5% of girls and 1% of boys . There is growing concern regarding the resistance of urinary pathogens to commonly used antibiotics because of the increasing number of therapeutic failures after empiric treatment . To ensure appropriate treatment, knowledge of the organisms that cause UTI and their antibiotic susceptibility is mandatory . They need to be constantly reevaluated to achieve maximal clinical response before the antibiotic susceptibility of the isolate is known. The aim of this study was to assess the susceptibility of urinary pathogens to commonly used antibiotics in Turkish children with community- acquired UTI.
