Diagnosis in young healthy women can be based on symptoms alone.
In those with vague symptoms, diagnosis can be difficult because bacteria may be present without there being an infection. In complicated cases or if treatment fails, a urine culture may be useful.
In uncomplicated cases, UTIs are treated with a short course of antibiotics such as nitrofurantoin or trimethoprim/sulfamethoxazole. Resistance to many of the antibiotics used to treat this condition is increasing.
In those with frequent infections, a short course of antibiotics may be taken as soon as symptoms begin or long-term antibiotics may be used as a preventative measure.
About 150 million people develop a urinary tract infection in a given year. They are more common in women than men. Up to 10% of women have a urinary tract infection in a given year, and half of women have at least one infection at some point in their lifetime.
