Epidemiología y etiología de la infección urinaria comunitaria. Sensibilidad antimicrobiana de los principales patógenos y significado clínico de la resistencia

Rates of resistance have undergone considerable variations, and consequently the empirical treatment of UTI requires constant updating of the antibiotic sensitivity of the main uropathogens of the area, country or institution. To correctly interpret the global data on sensitivity, the type of UTI (uncomplicated versus complicated), sex, age and previous antibiotic therapy in each patient must be taken into account. Resistance in uncomplicated UTI has clinical significance (although less than in systemic infections such as bacteremia), which depends on whether the infection is cystitis or pyelonephritis.
