By Mayo Clinic staffA urinary tract infection is an infection that begins in your urinary system. Your urinary system is composed of the kidneys, ureters, bladder and urethra. Any part of your urinary system can become infected, but most infections involve the lower urinary tract — the urethra and the bladder.
Women are at greater risk of developing a urinary tract infection than are men. A urinary tract infection limited to your bladder can be painful and annoying. However, serious consequences can occur if a urinary tract infection spreads to your kidneys.
Antibiotics are the typical treatment for a urinary tract infection. But you can take steps to reduce your chance of getting a urinary tract infection in the first place.
