    What is UTI

    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.

    What are the symptoms

    Urinary tract infections don't always cause signs and symptoms, but when they do they may include:

    • A strong, persistent urge to urinate
    • A burning sensation when urinating
    • Passing frequent, small amounts of urine

    Symptoms (Continued)

    • Urine that appears cloudy, red, bright pink or cola-colored — a sign of blood in the urine
    • Strong-smelling urine
    • Pelvic pain, in women — especially in the center of the pelvis and around the area of the pubic bone

    What's the difference causes

    Depending on which part of the urinary tract is infected, the symptoms show up is also different. There are three main parts of the tract that could be infected: 

    • Kidneys (acute pyelonephritis)
    • Bladder (cystitis)
    • Urethra (urethritis)

    One main cause

    Infection of the bladder (cystitis). This type of UTI is usually caused by Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal (GI) tract. However, sometimes other bacteria are responsible.

    The other main cause

    Infection of the urethra (urethritis). This type of UTI can occur when GI bacteria spread from the anus to the urethra. Also, because the female urethra is close to the vagina, sexually transmitted infections, such as herpes, gonorrhea, chlamydia and mycoplasma, can cause urethritis.
