A urinary tract infection (UTI) is an infection in any part of your urinary system — your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract — 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.

Symptoms

Symptoms of a UTI depend on what part of the urinary tract is infected.

Lower tract UTI symptoms

Lower tract UTIs affect the urethra and bladder. Symptoms of a lower tract UTI include:

  • burning with urination
  • increased frequency of urination without passing much urine
  • increased urgency of urination
  • bloody urine
  • cloudy urine
  • urine that looks like cola or tea
  • urine that has a strong odour
  • pelvic pain in women
  • rectal pain in men

Upper tract UTI symptoms

Upper tract UTIs affect the kidneys. These can be potentially life threatening if bacteria move from the infected kidney into the blood. This condition, called urosepsis, can cause dangerously low blood pressure, shock, and death.

Symptoms of an upper tract UTI include:

  • pain and tenderness in the upper back and sides
  • chills
  • fever
  • nausea
  • vomiting

UTIs may be overlooked or mistaken for other conditions in older adults.

UTI symptoms in men

Symptoms of an upper tract urinary infection in men are similar to those in women. However, men with a lower tract UTI may sometimes also experience rectal pain

Types of urinary tract infection

Each type of UTI may result in more-specific signs and symptoms, depending on which part of your urinary tract is infected.
