In nonpregnant women, asymptomatic bacteriuria increases the risk of cystitis, but neither general screening nor treatment is recommended because bacteriuria tends to rapidly recur. Likewise, there is no benefit to general screening or treatment of asymptomatic bacteriuria in men. In diabetic patients, treating asymptomatic bacteriuria has not been shown to decrease or delay future urinary tract infections. Similarly, in elderly individuals residing in long-term care facilities, the treatment of asymptomatic bacteriuria has failed to show benefits. In patients with chronic indwelling catheters, research comparing treatment with a placebo has shown no difference in infection rates and demonstrated higher rates of antibiotic resistance among patients receiving treatment.
