embolization is a minimally invasive treatment for hypertrophy of the prostate.
Through the microcatheter injection of microspheres to block the blood vessels
of the prostate, the tissue ischemia and atrophy. Arterial embolization has a
good therapeutic effect and is less invasive than traditional surgery. It only
needs local anesthesia, the wound is only as big as a pinhole, does not require
catheterization, and recovers quickly. It has fewer side effects and no
Symptoms of an Enlarged Prostate
you or your family members have difficulty urinating, weak urination, or
intermittent urination? Do you have difficulty holding back urine? Do you
urinate frequently but not cleanly? Do you often need to get up at night to
urinate and cannot sleep well? If you have the above symptoms, you may have an
hypertrophy is a problem that most mature men will encounter, and the
probability increases with age. According to statistics, about half of men aged
50–60 and about 70% of men aged 60-70 have prostatic hypertrophy . Clinical
symptoms are mainly related to urinary tract obstruction. Symptoms include:
inability to urinate, intermittent urine flow, need to force the abdomen to
force urine, inability to completely empty the bladder, frequent urination,
urgency or frequent nocturia, which affect the quality of daily life. Severe
cases may even lead to obstruction of the bladder outlet, urine retention
requiring catheterization or obstruction leading to hydronephrosis, urinary
tract infection or even renal failure.
Treatment for an Enlarged Prostate
According to clinical
treatment guidelines, drug treatment is generally given first. For patients who
do not respond well to drugs, cannot tolerate drug side effects, or have severe
initial symptoms, transurethral prostatectomy is a further treatment option.
Now there is a new treatment method that can replace surgery - "prostate
Prostate Artery Embolization
artery embolization is a procedure in which physicians use very thin catheters
to enter from the hand or leg arteries, place microcatheters deeply in the tiny
prostatic arteries, and then inject microspheres for embolization into the
prostatic artery through the microcatheters. By blocking the prostate artery,
the hypertrophic prostate tissue undergoes ischemia and atrophy. Then the
volume of the prostate is reduced, and the obstruction of the urinary tract is
relieved. The treatment time is about two hours.
advantages of arterial embolization include the fact that only local anesthesia
is required and no semi-anesthesia is required. The wound is only as big as a
pinhole, and the blood loss is less. Urethral catheterization is not required.
The pain during and after the operation is mild. Only a short stay in the
hospital is needed. It will not cause surgery-related complications such as
urinary incontinence, urethral and bladder neck stenosis, sexual dysfunction,
retrograde ejaculation, etc. After embolization, the use of prostatic
hypertrophy drugs and related side effects such as postural hypotension or
sexual dysfunction can be avoided or reduced. Arterial embolization is
especially suitable for patients who want to receive minimally invasive
treatment, elderly patients with high surgical or anesthesia risks, patients
with cardiovascular diseases, those who need to take anticoagulants for a long
time and have bleeding risks, and those who have doubts about surgery or
anesthesia and are unwilling to undergo surgery Patients, those with busy work
or life schedules who need to return to their original work or lifestyle as
soon as possible.
artery embolization has been practiced in Europe and the United States for many
years, and the technology is quite mature. Rigorous and sufficient studies have
confirmed its safety and effectiveness. It can effectively improve the clinical
symptoms of prostatic hypertrophy, improve the quality of life, significantly
increase the urine flow rate, reduce the volume of the prostate, and reduce the
prostate specific antigen. Some patients will have temporary difficulty
urinating, hematuria, or bloody stools within one week after the operation, and
they will return to normal about one week after the operation. Eighty-five
percent of the patients' symptoms related to benign prostatic hypertrophy can
be significantly improved within half a month to one month, and seventy percent
of the patients can maintain the effect for more than five years. The effect of
improving symptoms is about the same as that of transurethral prostatectomy.
The disadvantage of arterial embolization is the need to inject
iodine-containing contrast medium, there may be concerns about renal function,
and health insurance does not cover it.
arterial embolization is widely recognized by patients all over the world due
to its low invasiveness, low side effects, and effectiveness as a treatment.
However, the physical condition and severity of each patient with hypertrophy
of the prostate are different. There is no certain standard answer for
treatment, and no treatment method is suitable for everyone. If you have
related troubles, you can consult a professional and experienced doctor to
understand and choose the most suitable treatment method for you. If you or
your family members have any questions or needs, please go to the outpatient
clinic of our hospital for consultation.
