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 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:
- prostatitis (infection of the prostate gland)
- urethritis (infection of the urethra), usually caused by
sexually transmitted diseases
- cystitis (infection of the bladder), which is more common
in elderly men
- pyelonephritis (infection of the kidney), which is rare
in men but can be serious.
What are the symptoms?
The symptoms of urinary tract infection may include:
- pain and discomfort (burning) when urinating
- frequent and urgent need to urinate (especially at night)
- urethral discharge (a clear fluid or small amount of pus
from the penis, more common with sexually transmitted
diseases)
- abdominal pain
- fever
- blood in the urine
- back pain (prostatitis may cause low back pain while a
kidney infection may cause mid-back pain).
How is it diagnosed?
Your health care provider will ask about your symptoms and
medical history. Your provider will examine you, including
an exam of the prostate with a rectal exam. Your provider
may also order lab tests of the urine and discharge from
the urethra and prostate gland.
For serious or repeated infections, you may need:
- an ultrasound, a technique that produces images of soft
tissues and fluids
- IVP (intravenous pyelography), which gives x-ray pictures
of the urinary system
- cystoscopy, a procedure in which your health care
provider can see the urethra and bladder through a
viewing tube inserted (after anesthesia) into the
urethra.
How is it treated?
UTIs are treated with antibiotics. Your health care
provider may also prescribe a drug for burning and
discomfort.
For most UTIs, the symptoms go away within 24 hours after
you begin treatment. Make sure you finish all of the
antibiotic to prevent recurrence of the infection.
How can I take care of myself?
If you have the symptoms of a urinary tract infection:
- Follow the treatment prescribed by your health care
provider.
- Maintain good personal cleanliness.
- Drink plenty of fluids.
- Empty your bladder completely when you urinate.
- Keep your follow-up appointment with your provider, if
recommended.
For a fever:
- If you have a fever above 100°F (37.8°C), stay in bed.
After your temperature has fallen below 100°F, become as
active as you comfortably can.
- Ask your health care provider what you should take to
control your fever.
- Keep a daily record of your temperature.
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. Put on a
t-shirt and keep it between your skin and the hot water bottle
or heating pad, or wrap the hot water bottle or heating pad
in a washcloth, towel, or pillowcase. Check your skin to
make sure there is no irritation or burning. Don't fall
asleep while you are using the heating pad.
Call your health care provider if:
- You keep having symptoms.
- Your symptoms get worse.
- You develop new symptoms.
How can I avoid getting a urinary tract infection?
To help prevent a urinary tract infection:
- Drink lots of fluids every day.
- Empty your bladder often and completely.
- Practice safe sex. Always use latex or polyurethane
condoms.
- Urinate after sex to flush out bacteria.
- If you are uncircumcised, wash under the foreskin each
time you take a bath or shower.
