Abstract

Introduction: urinary tract infection (UTI) is one of the most prevalent diseases in clinical practice. In order to improve empirical treatment, the etiology of pediatric urinary tract infections and the antibiotic sensitivity profile of the responsible microorganisms have been studied.

Material and methods: cross-sectional, descriptive and retrospective study (2020-2021) in which isolated microorganisms with significant counts in urine samples from patients with UTI were included. The global etiology and according to age and sex were analyzed. Only one urine sample per patient and UTI episode was considered.

Results: Escherichia coli was the most isolated microorganism both in the population as a whole (62%) and in each of the groups analyzed according to age and sex. It was isolated in women significantly higher than in men (χ², p=0.043). Their sensitivity was: 94% fosfomycin and 86% amoxicillin-clavulanic acid.

Conclusions: Escherichia coli continues to be the most frequently isolated microorganism in UTI. Therefore, for lower UTIs, amoxicillin-clavulanic acid and nitrofurantoin could be suitable options. Our environment should recommend fosfomycin, since it shows several advantages for its use, such as once-daily dosing, low side effects, adequate clinical and microbiological results, and little effect on the intestinal microbiota.
