Question: What are the treatments for Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: Treatment options for benign prostatic hyperplasia may include
- lifestyle changes - medications - minimally invasive procedures - surgery
A health care provider treats benign prostatic hyperplasia based on the severity of symptoms, how much the symptoms affect a mans daily life, and a mans preferences.
Men may not need treatment for a mildly enlarged prostate unless their symptoms are bothersome and affecting their quality of life. In these cases, instead of treatment, a urologist may recommend regular checkups. If benign prostatic hyperplasia symptoms become bothersome or present a health risk, a urologist most often recommends treatment.
Lifestyle Changes
A health care provider may recommend lifestyle changes for men whose symptoms are mild or slightly bothersome. Lifestyle changes can include
- reducing intake of liquids, particularly before going out in public or before periods of sleep - avoiding or reducing intake of caffeinated beverages and alcohol - avoiding or monitoring the use of medications such as decongestants, antihistamines, antidepressants, and diuretics - training the bladder to hold more urine for longer periods - exercising pelvic floor muscles - preventing or treating constipation
Medications
A health care provider or urologist may prescribe medications that stop the growth of or shrink the prostate or reduce symptoms associated with benign prostatic hyperplasia:
- alpha blockers - phosphodiesterase-5 inhibitors - 5-alpha reductase inhibitors - combination medications
Alpha blockers. These medications relax the smooth muscles of the prostate and bladder neck to improve urine flow and reduce bladder blockage:
- terazosin (Hytrin) - doxazosin (Cardura) - tamsulosin (Flomax) - alfuzosin (Uroxatral) - silodosin (Rapaflo)
Phosphodiesterase-5 inhibitors. Urologists prescribe these medications mainly for erectile dysfunction. Tadalafil (Cialis) belongs to this class of medications and can reduce lower urinary tract symptoms by relaxing smooth muscles in the lower urinary tract. Researchers are working to determine the role of erectile dysfunction drugs in the long-term treatment of benign prostatic hyperplasia.
5-alpha reductase inhibitors. These medications block the production of DHT, which accumulates in the prostate and may cause prostate growth:
- finasteride (Proscar) - dutasteride (Avodart)
These medications can prevent progression of prostate growth or actually shrink the prostate in some men. Finasteride and dutasteride act more slowly than alpha blockers and are useful for only moderately enlarged prostates.
Combination medications. Several studies, such as the Medical Therapy of Prostatic Symptoms (MTOPS) study, have shown that combining two classes of medications, instead of using just one, can more effectively improve symptoms, urinary flow, and quality of life. The combinations include
- finasteride and doxazosin - dutasteride and tamsulosin (Jalyn), a combination of both medications that is available in a single tablet - alpha blockers and antimuscarinics
A urologist may prescribe a combination of alpha blockers and antimuscarinics for patients with overactive bladder symptoms. Overactive bladder is a condition in which the bladder muscles contract uncontrollably and cause urinary frequency, urinary urgency, and urinary incontinence. Antimuscarinics are a class of medications that relax the bladder muscles.
Minimally Invasive Procedures
Researchers have developed a number of minimally invasive procedures that relieve benign prostatic hyperplasia symptoms when medications prove ineffective. These procedures include
- transurethral needle ablation - transurethral microwave thermotherapy - high-intensity focused ultrasound - transurethral electrovaporization - water-induced thermotherapy - prostatic stent insertion
Minimally invasive procedures can destroy enlarged prostate tissue or widen the urethra, which can help relieve blockage and urinary retention caused by benign prostatic hyperplasia.
Urologists perform minimally invasive procedures using the transurethral method, which involves inserting a cathetera thin, flexible tubeor cystoscope through the urethra to reach the prostate. These procedures may require local, regional, or general anesthesia. Although destroying troublesome prostate tissue relieves many benign prostatic hyperplasia symptoms, tissue destruction does not cure benign prostatic hyperplasia. A urologist will decide which procedure to perform based on the mans symptoms and overall health.
Transurethral needle ablation. This procedure uses heat generated by radiofrequency energy to destroy prostate tissue. A urologist inserts a cystoscope through the urethra to the prostate. A urologist then inserts small needles through the end of the cystoscope into the prostate. The needles send radiofrequency energy that heats and destroys selected portions of prostate tissue. Shields protect the urethra from heat damage.
Transurethral microwave thermotherapy. This procedure uses microwaves to destroy prostate tissue. A urologist inserts a catheter through the urethra to the prostate, and a device called an antenna sends microwaves through the catheter to heat selected portions of the prostate. The temperature becomes high enough inside the prostate to destroy enlarged tissue. A cooling system protects the urinary tract from heat damage during the procedure.
High-intensity focused ultrasound. For this procedure, a urologist inserts a special ultrasound probe into the rectum, near the prostate. Ultrasound waves from the probe heat and destroy enlarged prostate tissue.
Transurethral electrovaporization. For this procedure, a urologist inserts a tubelike instrument called a resectoscope through the urethra to reach the prostate. An electrode attached to the resectoscope moves across the surface of the prostate and transmits an electric current that vaporizes prostate tissue. The vaporizing effect penetrates below the surface area being treated and seals blood vessels, which reduces the risk of bleeding.
Water-induced thermotherapy. This procedure uses heated water to destroy prostate tissue. A urologist inserts a catheter into the urethra so that a treatment balloon rests in the middle of the prostate. Heated water flows through the catheter into the treatment balloon, which heats and destroys the surrounding prostate tissue. The treatment balloon can target a specific region of the prostate, while surrounding tissues in the urethra and bladder remain protected.
Prostatic stent insertion. This procedure involves a urologist inserting a small device called a prostatic stent through the urethra to the area narrowed by the enlarged prostate. Once in place, the stent expands like a spring, and it pushes back the prostate tissue, widening the urethra. Prostatic stents may be temporary or permanent. Urologists generally use prostatic stents in men who may not tolerate or be suitable for other procedures.
Surgery
For long-term treatment of benign prostatic hyperplasia, a urologist may recommend removing enlarged prostate tissue or making cuts in the prostate to widen the urethra. Urologists recommend surgery when
- medications and minimally invasive procedures are ineffective - symptoms are particularly bothersome or severe - complications arise
Although removing troublesome prostate tissue relieves many benign prostatic hyperplasia symptoms, tissue removal does not cure benign prostatic hyperplasia.
Surgery to remove enlarged prostate tissue includes
- transurethral resection of the prostate (TURP) - laser surgery - open prostatectomy - transurethral incision of the prostate (TUIP)
A urologist performs these surgeries, except for open prostatectomy, using the transurethral method. Men who have these surgical procedures require local, regional, or general anesthesia and may need to stay in the hospital.
The urologist may prescribe antibiotics before or soon after surgery to prevent infection. Some urologists prescribe antibiotics only when an infection occurs.
Immediately after benign prostatic hyperplasia surgery, a urologist may insert a special catheter, called a Foley catheter, through the opening of the penis to drain urine from the bladder into a drainage pouch.
TURP. With TURP, a urologist inserts a resectoscope through the urethra to reach the prostate and cuts pieces of enlarged prostate tissue with a wire loop. Special fluid carries the tissue pieces into the bladder, and the urologist flushes them out at the end of the procedure. TURP is the most common surgery for benign prostatic hyperplasia and considered the gold standard for treating blockage of the urethra due to benign prostatic hyperplasia.
Laser surgery. With this surgery, a urologist uses a high-energy laser to destroy prostate tissue. The urologist uses a cystoscope to pass a laser fiber through the urethra into the prostate. The laser destroys the enlarged tissue. The risk of bleeding is lower than in TURP and TUIP because the laser seals blood vessels as it cuts through the prostate tissue. However, laser surgery may not effectively treat greatly enlarged prostates.
Open prostatectomy. In an open prostatectomy, a urologist makes an incision, or cut, through the skin to reach the prostate. The urologist can remove all or part of the prostate through the incision. This surgery is used most often when the prostate is greatly enlarged, complications occur, or the bladder is damaged and needs repair. Open prostatectomy requires general anesthesia, a longer hospital stay than other surgical procedures for benign prostatic hyperplasia, and a longer rehabilitation period. The three open prostatectomy procedures are retropubic prostatectomy, suprapubic prostatectomy, and perineal prostatectomy. The recovery period for open prostatectomy is different for each man who undergoes the procedure. However, it typically takes anywhere from 3 to 6 weeks.4
TUIP. A TUIP is a surgical procedure to widen the urethra. During a TUIP, the urologist inserts a cystoscope and an instrument that uses an electric current or a laser beam through the urethra to reach the prostate. The urologist widens the urethra by making a few small cuts in the prostate and in the bladder neck. Some urologists believe that TUIP gives the same relief as TURP except with less risk of side effects.
After surgery, the prostate, urethra, and surrounding tissues may be irritated and swollen, causing urinary retention. To prevent urinary retention, a urologist inserts a Foley catheter so urine can drain freely out of the bladder. A Foley catheter has a balloon on the end that the urologist inserts into the bladder. Once the balloon is inside the bladder, the urologist fills it with sterile water to keep the catheter in place. Men who undergo minimally invasive procedures may not need a Foley catheter.
The Foley catheter most often remains in place for several days. Sometimes, the Foley catheter causes recurring, painful, difficult-to-control bladder spasms the day after surgery. However, these spasms will eventually stop. A urologist may prescribe medications to relax bladder muscles and prevent bladder spasms. These medications include
- oxybutynin chloride (Ditropan) - solifenacin (VESIcare) - darifenacin (Enablex) - tolterodine (Detrol) - hyoscyamine (Levsin) - propantheline bromide (Pro-Banthine)
