Explanation	[[Explanation::This patient has a typical history of acute uncomplicated cystitis. The strongest risk factor is sexual intercourse,which facilitates the entry of bacterial flora into the genitourinary mucosa. Some preventive measures to reduce the risk of cystitis are : Cleaning genital areas prior to and after sexual intercourse. For sexually active women, and to a lesser extent men, urinating within 15 minutes of sexual intercourse to allow the flow of urine to expel the bacteria before specialized extensions anchor the bacteria to the walls of the urethra. Having adequate fluid intake, especially water. Not resisting the urge to urinate. Taking showers, not baths, or urinating soon after taking a bath. Practicing good hygiene, including wiping from the front to the back to avoid contamination of the urinary tract by fecal pathogens. Educational Objective: The strongest risk factor for cystitis is sexual intercourse. References: Hooton TM. Clinical practice. Uncomplicated urinary tract infection.
