Chapter 35 RECURRENT URINARY TRACT INFECTION
In the general population, urinary tract infection (UTI) is primarily an infection of sexually active women; the prevalence of UTI in women outnumbers that in men by a ratio of 30:1. However, the prevalence of UTI increases in both sexes with advancing age, reducing the ratio to 2:1. Recurrent UTI is defined as three or more episodes of symptomatic bacteriuria within 1 year. A recurrent infection is one that occurs after documented, successful resolution of an antecedent infection.
