What is benign prostatic hyperplasia?
When the prostate gland becomes very large it may cause problems passing urine. BPH is not cancer and is a common part of aging.
The prostate gland is found only in males. It’s located in front of the rectum and below the bladder. It wraps around the urethra, the tube that carries urine out of the body. The prostate’s job is to make some of the fluid that protects and nourishes sperm cells in semen. This makes the semen more liquid.
BPH can raise levels of PSA (prostate-specific antigen). PSA is made by the prostate and can be measured with a blood test. An increased PSA level does not mean you have cancer. But the higher the PSA level, the higher the chance of having cancer.
Some symptoms of BPH and prostate cancer are the same. But BPH is not cancer and does not develop into prostate cancer.
What causes BPH?
The cause of BPH is not known. The prostate goes through 2 main periods of growth. In early puberty, it doubles in size. Then around age 25, the prostate starts to grow again. It continues to grow for most of a man’s life.
The continuing growth of the prostate may not cause problems until much later in life, when the second period of growth may result in BPH. It is a common problem for men starting in their 60s. And it is more likely for men in their 70s and 80s to have some symptoms of BPH.
What are the symptoms of BPH?
As the prostate grows, it presses against the urethra, the tube that carries urine out of the body. This interferes with urination. At the same time, the bladder wall becomes thicker and irritated, and begins to contract, even when it contains only small amounts of urine. This can cause more frequent urination. These changes cause the bladder muscle to weaken. It may not empty fully and can leave some urine behind. This leads to symptoms.
The following are the most common symptoms of BPH:
- Leaking or dribbling of urine
- Trouble starting urine stream
- More frequent urination, especially at night
- Urgency to urinate
- Holding urine (can’t pass urine)
- An interrupted, weak stream of urine
These problems may lead to one or more of the following if BPH is not treated:
- Loss of urine control
- Kidney damage
- Blood in the urine
- Bladder damage
- Urinary tract infections
- Bladder stones
- Inability to pass urine at all
The symptoms of BPH may look like other conditions or health problems. Always talk with a healthcare provider for a diagnosis.
How is BPH diagnosed?
Diagnosing benign prostatic hyperplasia (BPH) in its earlier stages can lower the risk of complications. Your healthcare provider will review your health history and do a physical exam. Other tests may include:
- Urine tests. To check for infection.
- Digital rectal exam. A procedure where the healthcare provider puts a gloved finger into the rectum to feel the part of the prostate next to the rectum.
- Ultrasound (sonography). An imaging test that uses high-frequency sound waves to create images of the prostate and nearby organs on a computer screen.
- Cystoscopy. A thin flexible tube and viewing device (cytoscope) is put into the penis and through the urethra. It lets the healthcare provider look at the bladder and urinary tract for structure changes or blockages.
- Urine flow study. A test where the man urinates into a device that measures how quickly the urine is flowing. Reduced flow may suggest BPH.
- Post void residual. A test like an ultrasound that measures that amount of urine in the bladder after urination.
How is BPH treated?
With time, BPH symptoms often need some kind of treatment. When the prostate is just mildly enlarged, treatment may not be needed. In fact, research has shown that, in some mild cases, some of the symptoms of BPH get better without treatment. The need to start treatment will be decided by you and your healthcare provider after careful evaluation of your symptoms. Regular check-ups are important, and they’re needed to watch for developing problems.
Treatment for BPH may include:
To remove only the enlarged tissue that is pressing against the urethra (the tube that carries urine out of the body), with the rest of the inside prostate left intact. Types of surgery often include:
- Transurethral surgery. No outside cut (incision) is needed. The surgeon reaches the prostate by putting a tool through the urethra.
- Transurethral resection of the prostate (TURP). A thin, narrow tube (resectoscope) is put into the urethra through the penis. The surgeon uses tools through the resectoscope to remove the prostate tissue blocking the urethra one piece at a time. The pieces of tissue are carried into the bladder. They are flushed out at the end of the surgery.
- Transurethral incision of the prostate. A procedure that widens the urethra by making small cuts where the urethra joins the bladder (the bladder neck), and in the prostate gland itself.
- Laser surgery. Using laser tools to cut away the prostate tissue blocking the urethra. The laser fiber is passed through the urethra to the prostate.
- Open surgery. Surgery that requires an incision (cut) in the skin. This is often done when the gland is very big, when there are complicating factors, or when the bladder has been damaged and needs to be fixed.
These may include:
- Transurethral microwave thermotherapy (TUMT). Microwaves are used to heat and destroy prostate tissue to reduce urinary frequency and urgency. A thin flexible tube is put into the urethra to get the microwaves to the right parts of the prostate.
- Medicines. These are used to shrink or at least stop the growth of the prostate without using surgery. Or to make the muscles around the urethra looser so urine flows more easily.
- Water-induced thermotherapy. Heated water is sent through a soft flexible tube into the urethra to heat and destroy prostate tissue.
- Urolift. Small stitches are placed into the sides of the prostate through a camera to pull the blocking prostate tissue open.
What are possible complications of BPH?
Delay in treatment can cause lasting (permanent) bladder damage that can’t be treated.
Living with BPH
Management of BPH may include:
- Lifestyle factors. Limit fluids in the evening, empty your bladder before going to bed, and don’t take water pills (diuretics) that are active at night. Not smoking can also help ease BPH symptoms.
- Dietary factors. Stay away from or reduce the amount of alcohol, coffee, and other fluids. This is especially important after dinner. A higher risk for BPH has been linked to a diet high in zinc, butter, and margarine. Men who eat lots of fruits are thought to have a lower risk for BPH.
- Don’t use medicines that worsen symptoms. Decongestants and antihistamines can slow urine flow in some men with BPH. Some antidepressants and diuretics can also make symptoms worse. Talk with your healthcare provider if you are taking any of these medicines.
- Kegel exercises. Repeated tightening and releasing the pelvic muscles is called Kegel exercises. These can help prevent leaking urine. Practice these exercises while urinating to train the specific muscle. To do Kegels, contract the muscle until the flow of urine decreases or stops. Then release the muscle.
Key points about BPH
- BPH is when the prostate gland becomes very large and may cause problems passing urine.
- The cause of BPH is not known. Growth of the prostate may not cause problems until much later in life.
- As the prostate enlarges, it presses on the urethra. This causes symptoms such as changes in urination.
- BPH may not need treatment. If needed, treatment includes medicines. It also includes various procedures and surgeries to remove the part of the prostate that’s pressing on the urethra.
- Management of BPH may include lifestyle changes.
