Benign Prostatic Hyperplasia (BPH)
The
prostate is an organ found in males that has an essential
function in human reproduction. It is a gland of the male
reproductive system that produces some of the fluid for semen,
which is used to transport sperm during the male orgasm. The
prostate is made up of various cell types that have complex
interactions which science still does not fully understand.
The prostate is located just below the bladder, in front
of the rectum. It wraps around the urethra which is the tube
that carries urine from the bladder out through the tip of
the penis. The prostate is normally very small, about the
size of a walnut and is made up of muscular and glandular
tissue.
As men age, it is possible for their prostate to increase
in size. By age 70, over 40% of men will have an enlargement
of the prostate. If the prostate becomes large enough it will
press against the urethra, decreasing the flow of urine, making
it weaker and slower. This is the condition known as Benign
Prostatic Hyperplasia (BPH).
When Does This Happen?
The prostate gland goes through two different growth periods.
When a male hits puberty the prostate will double in size.
It will then remain the same throughout puberty, until the
male reaches about age 25. The prostate will then go through
a second growth period which will make it larger, but will
not cause any significant problems until later in life. Men
rarely have prostate problems until they reach their 40’s.
However, by the time men reach their 60’s, more than
50% are affected, and over 90% are affected by the time they
are in their 70’s and 80’s.
Causes?
Throughout their lives, men produce testosterone, which
is an important male hormone that aids in reproduction, as
well as small amounts of estrogen, which is a female hormone.
As men age, their production of testosterone decreases which
results in a higher proportion of estrogen in the blood. Studies
have shown that higher levels of estrogen within the gland
may increase the activity of substances that promote cell
growth. This suggests that elevated levels of estrogen could
promote the onset of Benign Prostatic Hyperplasia.
Another supposition focuses on dihydrotestosterone (DHT),
or a substance that originates from testosterone within the
prostate. This substance is believed to help control its growth.
Studies have shown that as most animal’s age, they lose
their ability to produce DHT, but in humans, even one drop
will cause men to continue to produce high levels of DHT in
the prostate. This production could encourage the growth of
cells and promote BPH.
Symptoms:
There is a layer of tissue that surrounds the prostate,
and as it enlarges, this layer prevents it from expanding.
This causes the gland to press against the urethra which causes
the bladder wall to become thick and irritable. When this
happens, the bladder will begin to contract even when it only
contains small amounts of urine, ultimately leading to more
frequent urination. Over time, the bladder will weaken and
eventually lose the ability to empty itself. The urethra narrowing
and the bladder only empting partially, are two of the causes
for many of the problems associated with BPH.
There are three common symptoms, mostly dealing with problems
or changes in urination that most men endure when they have
BPH. These are more frequent urination (particularly at night),
an interrupted, weak stream and leaking or dribbling. The
size of the prostate will not always run in conjunction with
the severity of the symptoms. Often, men with greatly enlarged
prostates will have very minor symptoms.
Treatments:
When BPH is caught early, many doctors will wait to treat
the problem. If symptoms are not severe, many times they clear
themselves up. Routine checkups can help keep tract of the
progression of the prostate. If the problem persists, there
are several ways to treat BPH. It can be treated with medications,
non-surgical procedures or surgery.
Doctors have the option of using several different medications
to try and relax the muscle tissue in the prostate and the
bladder neck. This will relieve the pressure against the urethra
which will hopefully restore normal urine flow and reduce
bladder obstruction. Medications can also be used to inhibit
the production of dihydrotestosterone (DHT) which can lead
to prostate enlargement. This will hopefully hinder any excess
growth that could be damaging.
Non-surgical procedures use heat to destroy excess tissue
of the prostate. This procedure is known as transurethral
microwave thermotherapy (TUMT). TUMT sends microwaves of heat
through a catheter to selected parts of the prostate. A cooling
device is used to protect the bladder while this procedure
is being performed. The heat effectively destroys excessive
tissue in the prostate. This procedure is not a cure for BPH.
It does reduce symptoms associated with the prostate, but
Benign Prostatic Hyperplasia can return.
Most doctors recommend surgery as the best long-term solution
for patients with BPH. With surgery, the excessive, enlarged
tissue that is pressing against the urethra is removed and
the rest of the prostate tissue as well as the outside capsule
are left unharmed. Removal of the enlarged part of the prostate
is the most effective way to rid the body of BPH. Transurethral
surgery, Open surgery and Laser surgery are the three procedures
used to treat BPH. Discussing each with your doctor will enable
you to decide which surgery will be the most effective for
you.
Recovery:
After the surgery, some bleeding may show in the urine.
The blood is from blood clots that have formed to heal the
wound. Drinking lots of water will help to flush the clots
out of the bladder. Once home it is good to take it easy for
a few weeks. Strenuous activity could cause damage to the
wound. It will probably be a few months before you are completely
back to normal.
The most common problems that occur once patients return
home are bleeding and excessive urination. Both problems should
remedy themselves as you recover, but if they persist, your
doctor should be notified. BPH is a real problem that older
men face, but, like any problem, it has a solution. Getting
checked early for prostate problems is the best way to discover
abnormalities. Also, after treatment, yearly checkups will
ensure that the BPH is no longer affecting your prostate.
