Urinary tract infections (UTIs) are most often caused by bacteria that invade the urinary tract. The bacteria may come from outside the body. Or they may travel from the skin outside the rectum into the urethra. The urethra is the tube that carries urine from the bladder out of the body. Pain in or around the urinary tract is a common symptom for most UTIs.
Women more commonly get UTIs than men. That's because their urethra is shorter. Older men get UTIs more commonly than younger because older men may have an enlarged prostate. A UTI in a male is usually a sign that something is wrong with their urinary system. Using a catheter also increases the risk for UTI.
Most UTIs are treated with antibiotics. These kill the bacteria. How long you need to take them depends on the type of infection. Take antibiotics exactly as directed until all of the medicine is gone. If you don't, the infection may not go away and may become harder to treat in the future.
