I'm a 53yo male, have had two utis spaced 5.5 years apart. what is the best way for me to avoid getting another uti?

Recurrent UTI, male: Urinary tract infections in males often occur because of anatomic abnormalities like urethral or ureteral stricture, prostate gland enlargment partly blocking flow, kidney stones; or because the prostate gland is infected, often without symptoms. Men with recurrent UTI are especiallly likely to have one of these problems. See your doctor, or ask for referral to a urologist. Good luck!
