Abstract
A 28-year-old woman telephones her physician to report dysuria and urinary urgency during the preceding three days. She has had several previous urinary tract infections, including three during the past year. She is otherwise healthy, takes no medications, and is sexually active, using spermicide-coated condoms for contraception. She does not have fever, chills, vaginal discharge, or flank pain. How should she be evaluated and treated?
