Radical Prostatectomy:

Surgery
Overview
A
radical prostatectomy is an operation to
remove the prostate gland and some of the
tissue around it. It is done to remove prostate
cancer. This operation may be done by open
or laparoscopic surgery.
Open surgery
In
open surgery, the surgeon uses a large incision
to reach the prostate gland. Depending on
the case, the incision is made either in
the lower belly or in the groin between
the anus and the penis. When
the incision is made in the lower belly,
it is called the retropubic approach. A
radical prostatectomy using the retropubic
approach is the most common treatment for
prostate cancer. In this procedure, the
surgeon may also remove lymph nodes in the
area so that they can be tested for cancer.1
When the incision
is made in the groin, it is called the perineal
approach. The recovery time after this surgery
may be shorter than with the retropubic
approach. If the surgeon wants to remove
lymph nodes for testing, he or she must
make a separate incision. If the lymph nodes
are believed to be free of cancer based
on the grade of the cancer and results of
the PSA test, the surgeon may skip the lymph
node removal.
Laparoscopic
surgery
In
laparoscopic surgery, the surgeon makes
several small incisions in the belly. A
lighted viewing instrument called a laparoscope
is inserted into one of the incisions. The
surgeon uses special instruments to reach
and remove the prostate through the other
incisions. Men
who have laparoscopic surgery tend to lose
less blood during the operation and to recover
faster than men who have open surgery.2
Laparoscopic prostatectomy is not yet widely
available, and because it is a relatively
new technique, no results from long-term
follow-up after treatment are available.
The main goal
of either type of surgery is to remove all
the cancer. Sometimes that means removing
the prostate as well as the tissues around
it, including a set of nerves to the penis
that affect the man's ability to have an
erection. Some tumors can be removed using
a nerve-sparing technique, which means carefully
cutting around those nerves to leave them
intact. Nerve-sparing surgery sometimes
preserves the man's ability to have an erection.
What
To Expect After Surgery
Prostatectomy
usually requires general anesthesia and
a hospital stay of 2 to 4 days. A thin flexible
tube called a catheter usually is left in
your bladder to drain your urine for 1 to
3 weeks. Your doctor will give you instructions
about how to care for your catheter at home.
Bladder control can be poor for a few months
after the catheter is removed. While
prostatectomy often removes all cancer cells,
it is important to receive follow-up care,
which may lead to early identification and
treatment if your cancer comes back. Your
regular follow-up program may include:
- Physical
exams.
-
Prostate-specific antigen (PSA) tests,
to monitor PSA levels and to measure the
speed of any changes in those levels.
-
Digital rectal exams.
-
Biopsies as needed, to examine suspicious
tissue.
Why It Is Done
Radical
prostatectomy is most often used if testing
shows that the cancer has not spread outside
the prostate (stages I and II). Before
you have a radical prostatectomy, the lymph
nodes in your pelvis may be biopsied to
find out whether cancer is present. The
prostate usually is not removed if cancer
has spread to the lymph nodes. Although
radical prostatectomy is occasionally used
to relieve urinary obstruction in men with
more advanced (stage III) cancer, a different
operation, called a TURP, is most often
used for that purpose. Surgery usually is
not considered a cure for advanced cancer,
but it can help relieve symptoms.
How
Well It Works
Radical
prostatectomy is generally effective in
treating prostate cancer that has not spread.
Following surgery,
the stage of the cancer can be determined
based on how far it has spread. Survival
rates depend on the stage of the cancer
and are highest with early-stage cancer.
PSA levels
will drop almost to zero if the surgery
successfully removes the cancer and the
cancer has not spread.If
cancer has spread, advanced cancer may develop
even after the prostate has been removed.
Risks
Erection
problems
Up to 80% of men experience erection problems
after a prostatectomy.3 The nerves that
control a man's ability to have an erection
lie next to the prostate gland. They often
are damaged or removed during surgery. In
the months and years after surgery, most
men who had erection problems after prostatectomy
are able to regain their ability to have
erections:4
- 76%
of men younger than 60
-
56% of men age 60 to 65
- 47%
of men older than 65
Recovery depends on:4
- Whether
the man was able to have an erection before
surgery.
-
How the surgery affected the nerves that
control erections.
-
How old the man was at the time of surgery.
Urinary incontinence
Up to half of all men who have a radical
prostatectomy develop urinary incontinence,
ranging from a need to wear urinary incontinence
pads to occasional dribbling. Studies show
that one year later, between 15% and 50%
of men report urinary problems.3 The
urethra—the tube that carries urine from
your bladder—runs through the middle of
the doughnut-shaped prostate gland. In order
to remove the prostate, the surgeon must
cut the urethra and later reconnect it to
the bladder. Evidence shows that the greater
the surgeon's experience and skill in making
this reconnection, the lower the rate of
incontinence.5 Some
men may require treatment for incontinence
after prostatectomy, if urinary leakage
continues longer than 1 year.
Complications
Radical prostatectomy is major surgery,
so it carries the same general risks as
other major operations, including heart
problems, blood clots, allergic reaction
to anesthesia, blood loss, and infection
of the wound. These
additional complications can be caused by
radical prostatectomy:
- Erection
problems
-
Urinary incontinence
-
Damage to the urethra
-
Damage to the rectum
-
What To Think About
When
considering prostatectomy, take into account
your personal wishes, age, other medical
conditions you may have, the stage and grade
of your cancer, and your PSA level. Radiation
treatment or watching and waiting may be
reasonable alternatives. Surgery may completely
remove your prostate cancer. However, it
is not possible to know ahead of time whether
the cancer has spread beyond the prostate
and is not curable with surgery alone. Prostate
cancer often spreads to the nerves that
surround the prostate. These nerves control
a man's ability to have an erection. When
the nerves are removed along with the cancer,
the man will most likely have erection problems.
A nerve graft sometimes may be done to reduce
this chance. For this, the surgeon removes
part of a nerve that goes down the back
of the leg and attaches it to the nerves
where the prostate gland was. This surgery
seems to be helpful for some men, but not
for all. More research is needed to see
how well this surgery works to preserve
the man's ability to have an erection.
