- Injury to the belly, pelvis, or internal organs of the urinary tract
- Certain medicines
- Strenuous exercise
- Urinary tract infection or kidney infection
- Kidney stones
- Kidney disease
- Bleeding disorders, such as hemophilia
- Cancer of the prostate , kidney , or bladder
- Radiation of the pelvis for cancer treatment
- Certain congenital diseases, such as polycystic kidneys

Symptoms
You may not have any other symptoms.
You may also have symptoms related to the cause. For example, kidney stones can cause pain in the side, belly, or groin.
Diagnosis
You will be asked about your symptoms and health history. A physical exam will be done. You may be referred to a specialist.
To help find a cause, your doctor may do:
- Urine tests
- Blood tests
Your pelvic and belly structures may need to be viewed. This can be done with:
- Ultrasound
- CT scan
- X-ray
- Intravenous pyelogram
- MRI scan
- Cystoscopy —a scope is passed up into the bladder
Treatment
Some people will not need treatment. Symptoms may go away on their own.
In others, treatment will depend on the cause. Medicine or surgery may be needed.
Prevention
Prevention will depend on the cause.
