Causes

Trigonitis is caused by a change in cells. It is not clear why this happens in some people and not others. The change may be related to:

  • Bladder irritation
  • Urinary tract infections
  • Hormones

Risk Factors

Trigonitis is more common in women. It may also be more likely in people who have catheters in place for a long period of time.

Symptoms

Trigonitis may cause:

  • Pelvic pain
  • Problems passing urine
  • An increase in the urge to urinate

Diagnosis

The doctor will ask about symptoms and health history. A physical exam will be done. Tests may be done to rule out other problems that cause the same symptoms. Tests may include

  • Urine tests
  • Urine culture
  • Blood tests

Treatment

Trigonitis may pass on its own. Others may need treatment to ease symptoms. Medicine may help to:

  • Ease bladder spasms or pain
  • Treat any infections that may be present

Prevention

The risk of trigonitis may be lowered by limiting the use of catheters when possible.
