What is BPH?
To begin with, "benign" means not malignant. Prostatic simply means prostate. And hyperplasia means "excessive formation of cells." So when your doctor tells you "you suffer from benign prostatic hyperplasia or BPH," what he's really telling you is you have a nonmalignant enlarged prostate.
BPH: A Common Part of Aging
It is common for the prostate gland to become enlarged as a man ages. Doctors call the condition benign prostatic hyperplasia (BPH), or benign prostatic hypertrophy.
As a man matures, the prostate goes through two main periods of growth. The first occurs early in puberty, when the prostate doubles in size. At around age 25, the gland begins to grow again. This second growth phase often results,
years later, in BPH.
Though the prostate continues to grow during most of a man's life, the enlargement doesn't usually cause problems until late in life. BPH rarely causes symptoms before age 40, but more than half of men in their sixties and as many as 90 percent in their seventies and eighties have some symptoms of BPH.
As the prostate enlarges, the layer of tissue surrounding it stops it from expanding, causing the gland to press against the urethra like a clamp on a garden hose. The bladder wall becomes thicker and irritable. The bladder begins to contract even when it contains small amounts of urine, causing more frequent urination. Eventually, the bladder weakens and loses the ability to empty itself. Urine remains in the bladder. The narrowing of the urethra and partial emptying of the bladder cause many of the problems associated with BPH.
Many people feel uncomfortable talking about the prostate, since the gland plays a role in both sex and urination. Still, prostate enlargement is as common a part of aging as gray hair. As life expectancy rises, so does the occurrence of BPH. In the United States alone, 375,000 hospital stays each year involve a diagnosis of BPH.
It is not clear whether certain groups face a greater risk of getting BPH. Studies done over the years suggest that BPH occurs more often among married men than single men and is more common in the United States and Europe than in other parts of the world. However, these findings have been debated, and no definite information on risk factors exists.
The Benign Enlargement of the Prostate (BPH) is a kinds of fall off pathological changes. The men will begin different degree prostate hyperplasia from 30 years old. They will appear symptom after 50 years old. It is cause by the sex hormone excrete descend, nerve excrete maladjustment, and the diet factor. The Benign Enlargement of the Prostate can cause the temporary sex excited. This is because the prostate hyperplasia make the prostate function foul-up, feed back to cause the testicle function stronger. The sex living will make an Enlarged Prostate more bad, because the sex make the prostate congest for long time, aggravate the illness.Why BPH Occurs
The cause of BPH is not well understood. For centuries, it has been known that BPH occurs mainly in older men and that it doesn't develop in men whose testes were removed before puberty. For this reason, some researchers believe that factors related to aging and the testes may spur the development of BPH.
Throughout their lives, men produce both testosterone, an important male hormone, and small amounts of estrogen, a female hormone. As men age, the amount of active testosterone in the blood decreases, leaving a higher proportion of estrogen. Studies done with animals have suggested that BPH may occur because the higher amount of estrogen within the gland increases the activity of substances that promote cell growth.
Another theory focuses on dihydrotestosterone (DHT), a substance derived from testosterone in the prostate, which may help control its growth. Most animals lose their ability to produce DHT as they age. However, some research has indicated that even with a drop in the blood's testosterone level, older men continue to produce and accumulate high levels of DHT in the prostate. This accumulation of DHT may encourage the growth of cells. Scientists have also noted that men who do not produce DHT do not develop BPH.
Some researchers suggest that BPH may develop as a result of "instructions" given to cells early in life. According to this theory, BPH occurs because cells in one section of the gland follow these instructions and "reawaken" later in life. These "reawakened" cells then deliver signals to other cells in the gland, instructing them to grow or making them more sensitive to hormones that influence growth. Prostate enlargement can be associated with:-infections in the urine. The bacteria erode the prostate texture every day, so it can cause the prostate hyperplasia too.
Many symptoms of BPH stem from obstruction of the urethra and gradual loss of bladder function, which results in incomplete emptying of the bladder. The symptoms of BPH vary, but the most common ones involve changes or problems with urination, such as:
The size of the prostate does not always determine how severe the obstruction or the symptoms will be. Some men with greatly enlarged glands have little obstruction and few symptoms while others, whose glands are less enlarged, have more blockage and greater problems.
Sometimes a man may not know he has any obstruction until he suddenly finds himself unable to urinate at all. This condition, called acute urinary retention, may be triggered by taking over-the-counter cold or allergy medicines. Such medicines contain a decongestant drug, known as a sympathomimetic. A potential side effect of this drug may be to prevent the bladder opening from relaxing and allowing urine to empty. When partial obstruction is present, urinary retention also can be brought on by alcohol, cold temperatures, or a long period of immobility. Acute urinary retention causes severe pain and discomfort. Catheterization may be necessary to drain urine from the bladder and obtain relief.
It is important to tell your doctor about urinary problems such as those described above. In 8 out of 10 cases, these symptoms suggest BPH, but they also can signal other, more serious conditions that require prompt treatment. These conditions, including prostate cancer, can be ruled out only by a doctor's exam.
Severe BPH can cause serious problems over time. Urine retention and strain on the bladder can lead to urinary tract infections, bladder or kidney damage, bladder stones, and incontinence. If the bladder is permanently damaged, treatment for BPH may be ineffective. When BPH is found in its earlier stages, there is a lower risk of developing such complications.
You may first notice symptoms of BPH yourself, or your doctor may find that your prostate is enlarged during a routine checkup. When BPH is suspected, you may be referred to a urologist, a doctor who specializes in problems of the urinary tract and the male reproductive system. Several tests help the doctor identify the problem and decide whether surgery is needed. The tests vary from patient to patient, but the following are the most common.
Digital Rectal Exam (DRE)
This exam is usually the first test done. The doctor inserts a gloved finger into the rectum and feels the part of the prostate next to the rectum. This exam gives the doctor a general idea of the size and condition of the gland.
Prostate Specific Antigen (PSA) Blood Test
In order to rule out cancer as a cause of urinary symptoms, your doctor may recommend a PSA blood test. PSA, a protein produced by prostate cells, is frequently present at elevated levels in the blood of men who have prostate cancer. The U.S. Food and Drug Administration has approved a PSA test for use in conjunction with a digital rectal exam to help detect prostate cancer in men age 50 or older and for monitoring prostate cancer patients after treatment. However, much remains unknown about the interpretation of PSA levels, the test's ability to discriminate cancer from benign prostate conditions, and the best course of action following a finding of elevated PSA.
Because many unanswered questions surround the issue of PSA screening, the relative magnitude of its potential risks and benefits is unknown. Both PSA and ultrasound tests enhance detection when added to DRE screening. But they are known to have relatively high false-positive rates, and they may identify a greater number of medically insignificant tumors. Thus, PSA screening might lead to treatment of unproven benefit that could result in morbidity (including impotence and incontinence) and mortality. It cannot be determined from earlier studies whether PSA screening will reduce prostate cancer mortality. Ongoing studies are addressing this issue.
If there is a suspicion of prostate cancer, your doctor may recommend a test with rectal ultrasound. In this procedure, a probe inserted in the rectum directs sound waves at the prostate. The echo patterns of the sound waves form an image of the prostate gland on a display screen.
Urine Flow Study
Sometimes the doctor will ask a patient to urinate into a special device that measures how quickly the urine is flowing. A reduced flow often suggests BPH.
Intravenous Pyelogram (IVP)
IVP is an x ray of the urinary tract. In this test, a dye is injected into a vein, and the x ray is taken. The dye makes the urine visible on the x ray and shows any obstruction or blockage in the urinary tract.
In this exam, the doctor inserts a small tube through the opening of the urethra in the penis. This procedure is done after a solution numbs the inside of the penis so all sensation is lost. The tube, called a cystoscope, contains a lens and a light system, which help the doctor see the inside of the urethra and the bladder. This test allows the doctor to determine the size of the gland and identify the location and degree of the obstruction.
BPH and Prostate Cancer: No Apparent Relation
Although some of the signs of BPH and prostate cancer are the same, having BPH does not seem to increase the chances of getting prostate cancer. Nevertheless, a man who has BPH may have undetected prostate cancer at the same time or may develop prostate cancer in the future.
calcification is because your prostate was eroded by the bacteria every day, and the texture was damage. And the old men's sex hormone excrete maladjustment and reduce, so the prostate texture will enlarge, change rigidity, some body will cause calcification, it means that the texture is very hard in the calcification zone, and the blood circulation will change into putrescence in this zone, the toxin can't drain , the toxin will cause the prostate condition change and the cell aberrance , so some body will cause prostate cancer .
