Urinary Tract Infection In Men

What is a urinary tract infection?

A urinary tract infection (UTI) is caused by bacteria that get inside your urinary tract. Most bacteria that enter your urinary tract are expelled when you urinate. If the bacteria stay in your urinary tract, you may get an infection. Your urinary tract includes your kidneys, ureters, bladder, and urethra. Urine is made in your kidneys, and it flows from the ureters to the bladder. Urine leaves the bladder through the urethra. A UTI is more common in your lower urinary tract, which includes your bladder and urethra.

What increases my risk of a UTI?

  • Urinary tract problems: If you are not able to control when you urinate, your risk for a UTI increases. Your risk also increases if you have had a UTI or if you have had surgery on your urinary tract in the past.

  • Blockages: A blockage in your urinary tract stops your urine from flowing freely. Causes of a blockage include kidney and bladder stones.

  • Not being circumcised: The foreskin of the penis makes it easier for germs to get trapped and enter your urinary tract.

  • Prostate problems: An enlarged prostate gland or an infected prostate (prostatitis) increases your UTI risk.

  • Sexual intercourse: You are more likely to get an infection if your sex partner has an infection. Anal sex also increases your UTI risk.

  • Weak immune system: Your immune system is your body's defense against infection and disease. A weak immune system may not be able to fight the germs that can cause a UTI. Your immune system may become weak when you have a long-term illness, such as HIV or diabetes.

What are the signs and symptoms of a UTI?

  • Urinating more often or waking from sleep to urinate

  • Pain or burning when you urinate

  • Pain or pressure in your lower abdomen

  • Urine that smells bad

  • Leaking urine

How is a UTI diagnosed?

Your caregiver will ask about your signs and symptoms. He may press on your stomach, sides, and back to check if you feel pain. You may also need the following:

  • Urine tests: A sample of your urine is collected and sent to a lab for tests to learn what germ is causing your infection. You may be able to give a urine sample by urinating into a cup.

  • Blood tests: You may need blood tests to check if you have a prostate infection.

  • Imaging tests: You may need imaging tests if your UTI does not get better or you get another UTI. Imaging tests are pictures of your urinary tract that may show if your infection is in your kidneys. Imaging tests may also show if you have damage, blockages, or other problems in your urinary tract. You may be given a dye before the pictures are taken to help caregivers see the pictures better. Tell the caregiver if you have ever had an allergic reaction to contrast dye.

How is a UTI treated?

  • Antibiotics: This medicine is given to help treat or prevent an infection caused by bacteria.

  • Urinary tract medicines: These decrease pain and burning when you urinate. They will also help decrease the feeling that you need to urinate often. These medicines will make your urine orange or red.

What are the risks of a UTI?

If you take antibiotics for a long time, bacteria in your body can become resistant. Bacteria that are resistant to antibiotics are very hard to kill. Even after you take medicine to treat your UTI, your infection may come back. Without treatment, your infection and symptoms may get worse. The bacteria may spread to your kidneys and cause pyelonephritis. This can be a very serious condition, and you may need treatment in the hospital. The infection can spread to your blood, which can be life-threatening.

How can I prevent a UTI?

  • Urinate when you feel the urge: Do not hold your urine. Urinate as soon as you feel you have to.

  • Drink plenty of liquids: This may help you urinate more often. Ask how much liquid you should drink each day and which liquids are right for you.
