Diagnostic Procedure
Introduction
The most common reason this test is performed is because either a
blood test called PSA is abnormally high or the findings on examining
the prostate through the back passage are abnormal.
PSA
stands for prostate specific antigen.It is a substance produced
almost exclusively in the prostate and plays a role in fertility.The
vast majority is actually released into the ejaculate
but tiny amounts are released into the blood stream and can be detected
by a simple blood test.Abnormally high levels of PSA can be an indication
of disease of the prostate.Common reasons for a high PSA level in
the blood stream may include prostate cancer, large prostates, and
age related inflammation of the prostate or infection of the prostate.
Obviously the first concern is to exclude prostate cancer.
The bladder is the organ that stores urine and the urethra is the
tube that drains urine out
through the penis.The prostate lies immediately beneath the bladder
and completely
surrounds the urethra and lies immediately in front of the rectum
(back passage).Your
doctor would have performed on you a Digital Rectal Examination (DRE)
(examination via
the back passage) of the prostate, an otherwise inaccessible internal
organ. Age related enlargement is not a particular concern but if
the gland feels abnormally firm or hard, it
may sometimes be an indication of an abnormal growth in the prostate
gland.
Preparation for the test
You will have been provided with a prescription for a course of antibiotics.
The first tablet
should be taken on the morning of the test. The remaining tablets
should be taken as
directed until completion of the course. Although not critical,
but more your own comfort,
you should try to open your bowels prior to the procedure. There
is no need to fast for the
test (that is, you may eat and drink as desired right up until the
time of the test).
What actually happens?
A probe like instrument about 2.5 cm in diameter is gently inserted
into the back passage.
This is in fact an ultrasound probe that allows visualisation of the
prostate beyond what can
be felt by the finger alone. More importantly, it allows for
the placement of a special biopsy needle that collects samples of
your prostate. At the time of biopsy you will hear a loud
clicking noise that may startle you momentarily. You will feel
a slight sting as the needle
passes but it literally happens in a split second. A total of
6 biopsy specimens are usually collected.
The procedure takes about 20 minutes and you are able to drive home
if you desire but it is
often a good idea to have somebody with you due to the natural anxiety
you may have over
the anticipation of the results.
What risks are associated with the procedure?
Following a prostate biopsy you can expect to see some blood in the
urine, bowel motions
and in the semen. Any blood in the urine or bowel motions usually
settles by a week
although brownish discoloration of the semen can last for up to a
month. Uncommonly,
you may develop an infection but this risk is minimised by the antibiotics
administered.
If you develop fevers and begin to shake, which is rare, you should
go to the nearest
Emergency Department to be assessed.
Obtaining results
It generally takes up to a week to obtain the results of your biopsy.A
copy of the result
goes automatically to both your urologist and your referring family
doctor.It is critically
important that you have a follow up appointment within 7 days of the
procedure to follow
up on the results of the pathology.
