Content: Most of these infections involve Escherichia coli, Staphylococcus saprophyticus, or enterococci. The urine dipstick is a reasonable screening measure that can direct therapy if results are positive. Under the microscope in a clean sediment (free of epithelial cells), one WBC per 400 field suggests significant pyuria, although clinicians accustomed to imperfect samples usually set a threshold of 3 to 5 WBCs per field. In addition, Trichomonas organisms may be appreciated swimming in the urinary sediment, indicating a different cause for urinary symptoms or associated vaginitis. In a straightforward lower UTI, urine culture may be reserved for cases that fail to resolve with single-dose or 3-day therapy. In complicated or doubtful cases or with recurrences, a urine culture before initial treatment may be helpful. Risk factors for UTI in women include pregnancy, sexual activity, use of diaphragms or spermicides, failure to void postcoitally, and history of previous UTI. Healthy women may be expected to suffer a few episodes of lower UTI in a lifetime without indicating any major structural problem or incurring any long-term medical sequelae, but recurrences at short intervals suggest inadequate treatment or underlying abnormalities. Young men, however, have longer urethras and far fewer lower UTIs. They probably should be evaluated urologically after just one episode unless they have a risk factor such as an uncircumcised foreskin, HIV infection, or homosexual activity, and they respond successfully to initial treatment.
