Multiple sclerosis and asymptomatic urinary tract infection

Multiple sclerosis patients with bladder dysfunction are prone to have an asymptomatic urinary tract infection. Because bladder function abnormalities occur at some time in 70% to 90% of multiple sclerosis patients, a quantitative estimate of the bacterial concentration in the urine as well as a culture is mandatory. Treatment of bladder dysfunction or infection will vary according to the post-voiding residual volume. A patient with multiple sclerosis and asymptomatic urinary tract infection is reported that highlights strategies for the diagnosis and treatment of the urinary tract infection.
