Prostate
The prostate is a
gland only men have.
It is a gland producing most of the fluid
which is ejaculated (the semen and some of
the fluid are produced by the testis, the
epididymis and the seminal vesicles). |
The
prostatic fluid contains some sugars and
proteins (such as prostate-specific-antigen)
that are necessary for the fertility of the
ejaculate.
In most men the prostate will have the size (20
cc) and feel of a small plum, it can be reached
in a rectal examination.
The prostate is located near the urethra just
below the urinary bladder and consists of
glandular tissue and some smooth muscles.
The develoment of the prostate is dependent on
the male hormone testosterone (produced in the
testis). It grows during puberty and will not
grow or shrink in castrates.
Due
to its location and function prostate disorders
can result in severe problems.
Prostatitis:
An inflammation of the prostate
is called prostatitis.
The
experts know different types of inflammatory
disorders, whose symptoms and therapy are
different.
Bacterial inflammations (acute or chronic) are
treated with antibiotic medication.
In many cases the prostate inflammation will be
non-bacterial.
Many treatment options are used to cure the
inflammatory reaction and reduce the symptoms.
Prostatitis is a disease common in the daily
urologic practice and a severe problem for the
patients. Although it is a very frequent disease
therapy concepts are still very controversial.
The experienced urologist will combine medical
scientific results and therapy strategies as
well as personal experience and expertise to
select the individual therapy concept for his
patient.
Benign
Prostate Enlargement:
In many men the prostate will enlarge in his 50s
and 60s a very common finding. As the
prostate is locateted at the outlet of the
bladder an enlargement of the prostate will
often result in difficulties while urinating
the bladder does not empty completely any more:
getting up at night for urinating, dripping,
weak flow and eventually urinary infections can
be the result.
Modern oral medications will widen the bladder
outlet (such as alpha-blockers) or reduce the
size of the prostate (e.g. finasteride), but in
many cases the outlet obstruction will remain
and can often only by cured by urosurgical
therapy.
Within the last two decades many scientist have
tried to invent new techniques for the
urosurgical treatment of prostate enlargement
e.g. laser prostate therapy,
green-light-laser, thermo therapy and many
others. Many centers and companies are trying to
promote their instruments and systems to
participate in this multi-million-dollar market,
and especially laser therapy seems to attract
many patients.
However, today the transurethral resection of
the prostate (TUR-P), improved with new energy
applications systems, remains one of the safest
and most effective therapy options for bladder
outlet obstruction.
For patients with a smaller prostate Dr. Petsch
would recommend this well established method. In
the hand of an experienced surgeon the TUR-P is
the method that Dr. Petsch would select for
himself and his father.
For patients with a larger prostate (more than
80-100 gram) an open surgery might be the best
choice. Always try to find an urologist who does
a lot of prostate surgeries and TUR-P.
Prostate
cancer:
Prostate cancer is one of the most frequent
forms of cancer in men. Regular rectal
examinations and a PSA (prostate-specific-antigen)testing
can help to detect a prostate cancer at an early
stage prostate cancer can be cured.
Prostate cancer has the potential to spread
within the body mostly into the bones and
the lymph nodes. Symptoms of a prostate cancer
can be pain, erectile dysfunction, difficulty in
urinating and other symptoms.

The
prevalence of prostate cancer varies around the
world it is a common disease in the US and
Europe and less frequent in Asian countries.
However the differences can also be a result of
different detection rates. Many factors (e.g.
diet, genetics or sexual behaviour) are subjects
of an ongoing debate.
In the US prostate cancer is responsible for
more deaths than any other cancer except lung
cancer.
Most of the prostate cancer patients will be
older than 50 years.
Prostate cancer therapy can be surgery,
radiation therapy, hormonal therapy, (chemotherapy
less effective) or a combination of these.
Detection and diagnosis
The traditional screening procedure for
detecting prostate cancer is by DRE (digital
rectal exam). The doctor inserts a gloved
lubricated finger into the rectum to check the
prostate size and feel the back wall and sides
of the prostate for bumps or other abnormalities.
The exam is quick and generally painless and can
be a good indicator that further tests are
necessary.
An additional screening method that has
revolutionized prostate cancer detection is a
simple blood test to check PSA (Prostate
Specific Antigen) level. PSA is an enzyme
produced by prostate cells, whether normal or
cancerous. An abnormal prostate, including one
with cancer, will secrete more PSA. Since the
normal range of PSA is 0.0 - 4.0 ng/ml, a level
between 4 and 10 may raise suspicion that a
patient has prostate cancer. However, an
elevated level of PSA does not necessarily mean
that you have prostate cancer. Other factors
that can raise the PSA level are: inflammation
or infection of the prostate, non-cancerous
prostate growth (BPH), recent urinary
catheterization or procedure, recent prostate
biopsy or surgery, stones in the prostate or
bladder surgery.
If the DRE or PSA level indicates that cancer
may be present, your doctor will perform an
ultrasound and biopsy of the prostate. A
lubricated ultrasound probe is inserted in the
rectum and sound waves emitted by the probe
provide images of the entire prostate. Biopsies
of the prostate are taken with tiny hollow
needles inserted through the thin rectal wall.
Biopsy is the only definitive way to diagnose
the presence of prostate cancer.
The following criteria are used to characterize
prostate cancer: grade of the tumor (Gleason
score, where the higher the number the more
aggressive the cancer), stage of the tumor
(T1-T4, where the higher the number the more the
cancer has spread) and volume of the prostate.
An
important diagnostic step is the Prostate biopsy
in most of the cases done as a transrectal,
ultrasound-guided multifocal needle-biopsy. The
procedure can be done with local anaesthesia as
an outpatient procedure.
Prostate
cancer prevention
Screen for prostate cancer by having an annual
digital rectal exam and PSA blood test from age
50. If you are African American or have a family
history of prostate cancer you should have these
annual tests from age 40.
Brachytherapy
for prostate cancer:
Seed implantation with iodine-125 seeds (brachytherapy)
is a highly effective treatment for men with
prostate cancer. In a 10-year survivability
study, the success rate was demonstrated to be
better than external beam radiation and equal to
that of surgery. Brachytherapy requires no
surgical incision, offers men a shorter recovery
time, and has less chance of troubling side
effects such as impotence and incontinence.
Brachytherapy is an outpatient procedure and
most men go home the same day as their treatment.
Seed implantation takes only 45 minutes to 1
hour. External beam radiation requires 5
hospital visits each week for about 7 to 8 weeks.
With brachytherapy, most men can return to their
normal activities a few days after treatment.
Surgery requires hospitalization and takes many
weeks to heal.
Seed
implantation with iodine-125 seeds gives a lower
dose rate of radiation than palladium-103, and
as the seeds work in your body longer than
palladium-103, it is ideal for treating slow
growing tumors such as most prostate cancers.
When prostate cancer spreads to the tissue that
immediately surrounds the prostate, many doctors
choose RAPID Strand. The unique way the seeds
are linked together in RAPID Strand allows
doctors to securely place seeds directly in and
adjacent to the surrounding tissue, to treat
cancer that has extended outside of the prostate.
Implantation
of the seeds
Before an implantation, an ultrasound volume
study to see the size and location of the
prostate as well as the surrounding organs. 
During the pre-plan a predetermination is made
of how many seeds a patient will need and
exactly where they should be placed based on the
size and shape of the prostate. At the beginning
of the implantation, the patient will be
administered anesthesia.
To guide the precise placement of the seeds, an
ultrasound probe is placed in the rectum so that
an image of the prostate appears. Usually 80 to
100 seeds are placed inside needles that are
inserted in to the prostate. The ultrasound
probe ensures that the needles are guided with
maximum accuracy based on the plan.
The
entire implantation procedure usually takes only
45 minutes to 1 hour. After the seeds are
implanted, the patient will stay in a recovery
room. Since seed implantation is an outpatient
procedure, the patient can usually go home after
the anesthesia wears off.
Are
there any side effects?
There is little discomfort after the
implantation.
As might be expected, there may be some mild
soreness, some blood in the urine, and/or
bruising or swelling
between the legs.
These symptoms usually go away in a few days.
Some men may experience discomfort while
urinating, or the need to urinate more
frequently. These symptoms usually begin 1 to 2
weeks after implantation and gradually decrease
over time as the seeds lose their strength.
Drinking lots of fluids and avoiding caffeine
and alcohol may help relieve these symptoms. A
small percentage of men, particularly those who
have had previous prostate surgery, may
experience incontinence. Impotence may also
occur in some men, particularly those over the
age of 70. However, the rates of impotence and
incontinence are lower with Seed Brachytherapy
than with other treatments.
Does
the patient need to take
special precautions after the implantation?
Although seeds contains
radioactive material, the patient is not
radioactive.
One
of the benefits of seeds is that almost all
radiation stays within the prostate. After
implantation, the patient can continue to enjoy
physical contact with other adults.
As a precaution, the physician may suggest using
a condom during sex for a few days after the
procedure. A physician may also recommend that
patients avoid close contact with small children
and pregnant women for the first 2 months after
treatment.
