What is urinary tract infection in men?

Urinary tract infection (UTI) is an overgrowth of bacteria in the urethra, bladder, kidneys, or prostate gland. It can last a long time and, if left untreated, can cause permanent damage.

How does it occur?

Men rarely get urinary tract infections before age 50, but they are more common in older men. Men older than 50 may have an infection but no symptoms.

Urinary tract infection usually happens in older men who have an enlarged prostate or when a catheter is used to drain the bladder. In younger men it may be associated with a kidney stone.

Bacteria usually cause a urinary tract infection by spreading on the skin from the rectum into the urethra and then to the bladder or kidneys. Bacteria can also spread from another part of the body through the bloodstream into the urinary system. Urinary tract infection is less common in men than in women because the male urethra is long, making it difficult for bacteria to spread to the bladder.

An enlarged prostate can cause a urinary tract infection by preventing the urine from draining out of the bladder completely. A less common cause is urethral stricture, which is when the urethra becomes narrower because of scar tissue forming inside it. (The urethra is the small tube in the penis through which urine passes.)

Bacteria can cause various types of infections in the urinary tract, including:

For cramps or abdominal pain, you may want to use a hot water bottle or an electric heating pad on a low setting. Never put anything hot directly on your skin.
