** “Uncomplicated” means that the patient has no known factors that would make her more susceptible to develop a UTI, while '''“complicated” indicates infection with multi-drug resistant bacteria or presence of risk factor(s)''' for UTI and decreased treatment efficacy.

This guideline does not apply to complicated UTI or those exhibiting signs or symptoms of systemic bacteremia, such as fever and flank pain.
