A urinary tract infection (UTI) is an infection in any part of your urinary system including your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract which is the bladder and the urethra.
Women are at greater risk of developing a UTI than are men. Infection limited to your bladder can be painful and annoying. However, serious consequences can occur if a UTI spreads to your kidneys.
Doctors typically treat urinary tract infections with antibiotics. But you can take steps to reduce your chances of getting a UTI in the first place.
