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
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.
Trigonitis may cause:
- Pelvic pain
- Problems passing urine
- An increase in the urge to urinate
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
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
The risk of trigonitis may be lowered by limiting the use of catheters when possible.
