    Causes

    It is not clear why these cells change in some people and not others, but the change may be stimulated by:
    • Bladder irritation
    • Urinary tract infections

    Risk Factors

    Trigonitis is more common in women and people who have had a catheter in place for a long period of time.

    Symptoms

    Symptoms may include:
    • Pelvic pain
    • Difficulty urinating
    • An increase in the urge to urinate

    Diagnosis

    You will be asked about your symptoms and medical history. A physical exam will be done.
    Your bodily fluids may be tested. This can be done with:
    • Urine tests
    • Urine culture
    • Blood tests

    Treatment

    Talk with your doctor about the best treatment plan for you. In some cases, trigonitis may not need to be treated and will resolve on its own.

    Medications

    You may be advised to take antibiotics to treat infection. Your sexual partner may also be advised to take antibiotics to prevent trigonitis from returning.

    Prevention

    If you have a catheter, talk to your doctor about how long it should be in place. Long-term use may result in trigonitis.
