Digital Rectal Examination (DRE)
Test Overview
A digital (finger) rectal examination is done to check for problems
with organs or other structures in the pelvis and lower belly. During the
examination, a health professional gently puts a lubricated, gloved finger of
one hand into the
rectum. He or she may use the other hand to press on
the lower belly or pelvic area.
A
digital
rectal exam is done for men as part of a complete physical examination
to check the
prostate gland. It is done for women as part of a
gynecological examination to check the uterus and
ovaries. Other organs, such as the bladder, can
sometimes also be felt during a digital rectal exam.
Why It Is Done
A
digital rectal exam (DRE) is done to:
- Check for growths in or enlargement of the
prostate
gland
in men. A tumor in the prostate can often be felt as a hard lump.
This may be done as part of a regular examination or to check on symptoms, such
as a change in urination. Not all problems of the prostate can be felt through
the rectum.
- Check for problems in a woman's
reproductive organs
, such as the uterus and ovaries.
It is often done during a regular
pelvic examination and
Pap test. It may also be done to check on symptoms,
such as pelvic pain or vaginal bleeding.
- Help find the cause of
symptoms such as rectal bleeding (blood in the stool), belly or pelvic pain, a
change in urination, or a change in bowel habits.
- Collect a stool
sample to test for blood in the stool.
- Check for
hemorrhoids or growths, such as cancer, in the rectum.
DRE alone is not used to diagnose
colorectal cancer. Also, a DRE may not find internal
hemorrhoids because they are soft and hard to feel; a
sigmoidoscopy may be needed to diagnose internal
hemorrhoids.
How To Prepare
If you have hemorrhoids, tell your health professional before the
examination begins. Your health professional will try not to bother your
hemorrhoids.
How It Is Done
For a digital rectal exam, you will take off your clothes below the
waist. You will be given a gown to wear.
- A man is often examined while he stands,
bending forward at the waist. A man can also be examined while lying on his
left side, with his knees bent toward his chest.
- A woman is often
examined while lying on her back on an examination table, with her feet raised
and supported by stirrups. A
rectovaginal exam is often done for women so that
organs in the pelvic area can be checked.
Your health professional gently puts a lubricated, gloved finger
into the rectum. He or she may use the other hand to press on the lower belly
or pelvic area to feel for tenderness or problems, such as enlargement,
hardness, or growths.
How It Feels
Men may feel some discomfort or pain during a digital rectal exam
(DRE). Your health professional must press firmly on the prostate to feel for
problems. This pressure may make you feel the need to urinate. The examination
may be painful if the prostate gland is swollen or irritated.
Most women do not find a DRE painful. You may feel some pressure or
discomfort when your health professional presses on your belly to feel the
internal organs.
People with hemorrhoids, breaks in the skin around the
anus (called
anal fissures), or other anal sores may find a DRE
more painful than people without these problems.
Risks
A small amount of bleeding from the rectum may occur after an
examination, especially if hemorrhoids fissures are present.
In rare cases, you may feel lightheaded and faint. This is called
vasovagal syncope and is caused by fear or pain when
your health professional puts a finger into the rectum. This is more likely to
happen if you are standing up.
Results

rectum.
Digital rectal exam
|
Normal:
|
No problems such as organ enlargements or growths are
felt.
|
|
Abnormal:
|
Problems such as organ enlargements or growths are
felt.
|
|
For men, the prostate gland may be enlarged. This may mean
benign prostatic hypertrophy (BPH) or inflammation of
the prostate gland (prostatitis). Tumors are
felt.
|
|
For women, growths such as tumors of the
cervix, uterus, or
ovaries are felt.
|
|
Growths such as
hemorrhoids, polyps, tumors, or
abscesses may be found in the lower rectum. Breaks in
the skin around the anus (anal fissures) may be found. Problems
of the bladder may also be felt.

What Affects the Test
Hemorrhoids or anal fissures may cause discomfort during a digital
rectal exam.
What To Think About
- If a digital rectal exam (DRE) is being done to
screen for prostate cancer, the examination may be combined with a blood test
for prostate-specific antigen (PSA). The two tests are often done together to
check for prostate cancer. Some organizations, such as the American Cancer
Society, recommend yearly DRE and PSA tests for men older than age 50. For more
information, see the medical test
Prostate-Specific Antigen (PSA).
- Other
tests may need to be done after a DRE if problems are felt. You may need a test
for blood in the stool or a visual examination of the anus and rectum
(anoscopy). For more information, see the medical tests
Sigmoidoscopy and
Fecal Occult Blood Test (FOBT).
- A
transrectal ultrasound and a prostate
biopsy may be done if the DRE or PSA test shows that
prostate cancer may be present. For more information, see the medical tests
Pelvic Ultrasound and
Prostate Biopsy.
- DRE alone is not used to
check for colorectal cancer. If problems are found during a DRE, more tests may
be needed, such as a
sigmoidoscopy,
colonoscopy or
barium enema. For more information, see the medical
tests
Sigmoidoscopy,
Colonoscopy, or
Barium Enema.
