Expressed Prostatic Secretions
Exam Overview Back to top
Examination of expressed prostatic secretions tests a sample of the secretion for signs of inflammation or bacterial infection.
While you bend over or lie on your side or back, the doctor inserts a lubricated, gloved finger into the rectum and presses each side of the prostate gland 6 or 7 times. The urethra is then gently "milked" with a gloved finger. The secretions are collected in a tube or on a swab.
The secretions are examined under a microscope for signs of inflammation and are cultured in the lab to find out if bacteria are present.
Why It Is Done Back to top
This test may be done if you have:
- Repeated urinary tract infections (UTIs).
- Symptoms that would suggest chronic bacterial prostatitis, chronic prostatitis/pelvic pain syndrome, inflammatory, or chronic prostatitis/pelvic pain syndrome, noninflammatory.
Results Back to top
Findings of expressed prostatic secretions may include the following.
Normal
This may also be called a negative result.
Microscopic
Few or no white blood cells are seen when the sample is viewed under a microscope.
Culture
No bacteria grow in the sample.
A negative culture may mean that the symptoms are caused by chronic prostatitis/pelvic pain syndrome, inflammatory or noninflammatory.
Abnormal
This may also be called a positive result.
Microscopic
White blood cells, pus cells, or other types of cells that point to inflammation are seen when the sample is viewed under the microscope.
Culture
Bacteria grow in the sample.
What To Think About Back to top
Your doctor may ask you to avoid ejaculation for 5 days prior to this test. This allows prostatic fluid to build up and prevents an increase in the number of white blood cells in the prostate fluid, which could interfere with test results.
The results of the test may help show which type of prostatitis is causing your symptoms. But this test often fails to provide conclusive evidence of the cause of symptoms.
