Prostatectomy
Prostatectomy is a surgery to remove all or part of the
prostate gland.
General information about Prostatectomy
The prostate gland is a fibrous organ that surrounds the urethra at the base of the
bladder in men. An enlarged prostate gland can compress the urethra, thus causing problems
with urination. Prostate enlargement may be caused by prostate gland overgrowth (benign
prostatic hypertrophy or hyperplasia) or prostate cancer.
Removal of the prostate gland can be performed in a number of different ways, depending on
the size of the prostate and the cause of the prostate enlargement (such as prostate
cancer).
Types of Prostatectomy
The three most common procedures for surgically removing the prostate for benign
disease include: transurethral resection of the prostate (TURP), suprapubic prostatectomy,
and transurethral incision of the prostate (TUIP).
The decision regarding the type of prostatectomy to perform depends on the size of your
prostate gland. Generally, for prostates less than 30 grams, TUIP is recommended.
For glands bigger than 30 grams and less than 80 grams (this number depends on the
experience of the surgeon), TURP is performed. If the prostate is bigger than 80 grams,
open prostatectomy is recommended.
Prostatectomy - TURP
Transurethral resection of the prostate is the gold standard treatment and most common
surgical procedure for benign prostatic hyperplasia (BPH). TURP is performed using spinal
or general anesthesia. A special kind of cystoscope (tubelike instrument) is inserted into
the penis through the urethra to reach the prostate gland.
A special cutting instrument is inserted through the cystoscope to remove the prostate
gland piece by piece. Blood vessels are cauterized (using heat to stop the bleeding) with
electric current during the surgery.
A Foley catheter (artificial tube to remove urine from
the body) is placed to help drain the bladder after surgery. The urine will initially
appear very bloody, but will clear with time.
A bladder irrigation solution may be attached to the catheter to continuously flush the
catheter, thus keeping it from becoming clogged with blood or tissue. The bleeding will
gradually decrease, and the catheter will be removed within 1-3 days. You will remain in
the hospital for 1 to 5 days.
OPEN PROSTATECTOMY
Although the transurethral approach is more commonly used, other surgical approaches to
removal of the prostate gland (such as the transvesical, retropubic, and suprapubic
approach) are sometimes used. The primary advantage of the transurethral approach is that
it does not create an external incision. However, it is difficult to remove a large
prostate using TURP.
To perform an open prostatectomy (sometimes called suprapubic or retropubic
prostatectomy), an incision is made in the lower abdomen between the umbilicus
(belly-button) and the penis through which the prostate gland is removed. This is a much
more involved procedure and usually requires a longer hospitalization and recovery period.
Open prostatectomy is performed using general or spinal anesthesia. You will return
from surgery with a Foley catheter in place. Occasionally, a suprapubic catheter will be
inserted in the abdominal wall to help drain the bladder.
A bladder irrigation solution may be attached to the catheter to continuously flush the
catheter, thus keeping it from becoming clogged with blood. A drainage tube may also be
placed in the abdominal cavity to drain excess blood and fluids from the area.
Your urine may initially appear very bloody, but this should resolve in a few days. The
Foley catheter and suprapubic catheters will remain in place for 5 days to a few weeks
until the bladder has sufficiently healed.
Prostatectomy - TUIP
Transurethral incision of the prostate (TUIP) is similar to TURP, but is usually
performed in people who have a relatively small prostate. This procedure is usually
performed on an outpatient basis and usually does not require a hospital stay.
A small incision is made in the prostatic tissue to enlarge the lumen (opening) of the
urethra and bladder outlet, thus improving the urine flow rate and reducing the symptoms
of BPH.
A Foley catheter may be placed to help drain the bladder after surgery. The catheter
will usually remain in place for a few days after surgery. Another key advantage to the
TUIP is the preservation of normal ejaculation.
Although orgasm is the same in both the TURP and TUIP, the TURP causes the ejaculate
fluid to be projected into the bladder instead of out the penis. The TUIP usually
continues to allow the ejaculate fluid to be expressed out the penis. Unfortunately, many
patients are not candidates for this surgery due to configuration of their prostates.
New techniques for Prostatectomy
Transurethral laser incision of the prostate (TULIP) and visual laser ablation (VLAP)
are two newer procedures that use lasers to cut out or destroy the prostate tissue. These
procedures are similar to the transurethral incision of the prostate (TUIP). Laser is
being evaluated for use in removal of prostatic tissue because of the ability to easily
control bleeding and decrease the amount of time required for healing.
Other treatments being investigated for treating the symptoms of prostate enlargement
include: microwave therapy of the prostate, balloon dilation of the prostatic urethra, and
placement of prostate stents that stretch open the narrowed urethral passage through the
prostate gland.
These procedures have demonstrated short term efficacy in select patients, but have not
had adequate long-term testing.
Symptoms of prostate enlargement and blockage (obstruction) include:
- Frequent urination with small amounts of urine
- Recent need to urinate at night (nocturia)
- Difficulty starting a stream of urine
- Slow stream of urine
- Urine dripping out of urethra after urination (dribbling)
- Feeling that bladder is never empty
- Urinary tract infection
