A wide variety of treatments are available for enlarged prostate, including medication, minimally invasive therapies and surgery. The best treatment choice for you depends on several factors, including:
- The size of your prostate
- Your age
- Your overall health
- The amount of discomfort or bother you are experiencing
If your symptoms are tolerable, you might decide to postpone treatment and simply monitor your symptoms. For some men, symptoms can ease without treatment.
Medication is the most common treatment for mild to moderate symptoms of prostate enlargement. The options include:
- Alpha blockers. These medications relax bladder neck muscles and muscle fibers in the prostate, making urination easier. Alpha blockers — which include alfuzosin (Uroxatral), doxazosin (Cardura), tamsulosin (Flomax) and silodosin (Rapaflo) — usually work quickly in men with relatively small prostates. Side effects might include dizziness and a harmless condition in which semen goes back into the bladder instead of out the tip of the penis (retrograde ejaculation).
- 5-alpha reductase inhibitors. These medications shrink your prostate by preventing hormonal changes that cause prostate growth. These medications — which include finasteride (Proscar) and dutasteride (Avodart) — might take up to six months to be effective. Side effects include retrograde ejaculation.
- Combination drug therapy. Your doctor might recommend taking an alpha blocker and a 5-alpha reductase inhibitor at the same time if either medication alone isn't effective.
- Tadalafil (Cialis). Studies suggest this medication, which is often used to treat erectile dysfunction, can also treat prostate enlargement.
Minimally invasive or surgical therapy
Minimally invasive or surgical therapy might be recommended if:
- Your symptoms are moderate to severe
- Medication hasn't relieved your symptoms
- You have a urinary tract obstruction, bladder stones, blood in your urine or kidney problems
- You prefer definitive treatment
Minimally invasive or surgical therapy might not be an option if you have:
- An untreated urinary tract infection
- Urethral stricture disease
- A history of prostate radiation therapy or urinary tract surgery
- A neurological disorder, such as Parkinson's disease or multiple sclerosis
Any type of prostate procedure can cause side effects. Depending on the procedure you choose, complications might include:
- Semen flowing backward into the bladder instead of out through the penis during ejaculation (retrograde ejaculation)
- Temporary difficulty with urination
- Urinary tract infection
- Erectile dysfunction
- Very rarely, loss of bladder control (incontinence)
There are several types of minimally invasive or surgical therapies.
Transurethral resection of the prostate (TURP)
A lighted scope is inserted into your urethra, and the surgeon removes all but the outer part of the prostate. TURP generally relieves symptoms quickly, and most men have a stronger urine flow soon after the procedure. After TURP you might temporarily need a catheter to drain your bladder.
Transurethral incision of the prostate (TUIP)
A lighted scope is inserted into your urethra, and the surgeon makes one or two small cuts in the prostate gland — making it easier for urine to pass through the urethra. This surgery might be an option if you have a small or moderately enlarged prostate gland, especially if you have health problems that make other surgeries too risky.
Transurethral microwave thermotherapy (TUMT)
Your doctor inserts a special electrode through your urethra into your prostate area. Microwave energy from the electrode destroys the inner portion of the enlarged prostate gland, shrinking it and easing urine flow. TUMT might only partially relieve your symptoms, and it might take some time before you notice results. This surgery is generally used only on small prostates in special circumstances because re-treatment might be necessary.
Transurethral needle ablation (TUNA)
In this procedure, a scope is passed into your urethra, allowing your doctor to place needles into your prostate gland. Radio waves pass through the needles, heating and destroying excess prostate tissue that's blocking urine flow. TUNA may be an option in select cases, but the procedure is rarely used any longer.
A high-energy laser destroys or removes overgrown prostate tissue. Laser therapy generally relieves symptoms right away and has a lower risk of side effects than does nonlaser surgery. Laser therapy might be used in men who shouldn't have other prostate procedures because they take blood-thinning medications.
The options for laser therapy include:
- Ablative procedures. These procedures vaporize obstructive prostate tissue to increase urine flow. Examples include photoselective vaporization of the prostate (PVP) and holmium laser ablation of the prostate (HoLAP). Ablative procedures can cause irritating urinary symptoms after surgery, so in rare situations another resection procedure might be needed at some point.
- Enucleative procedures. Enucleative procedures, such as holmium laser enucleation of the prostate (HoLEP), generally remove all the prostate tissue blocking urine flow and prevent regrowth of tissue. The removed tissue can be examined for prostate cancer and other conditions. These procedures are similar to open prostatectomy.
Prostatic urethral lift (PUL)
Special tags are used to compress the sides of the prostate to increase the flow of urine. The procedure might be recommended if you have lower urinary tract symptoms. PUL also might be offered to some men concerned about treatment impact on erectile dysfunction and ejaculatory problems, since the effect on ejaculation and sexual function is much lower with PUL that it is with TURP.
In this experimental procedure, the blood supply to or from the prostate is selectively blocked, causing the prostate to decrease in size. Long-term data on the effectiveness of this procedure aren't available.
Open or robot-assisted prostatectomy
The surgeon makes an incision in your lower abdomen to reach the prostate and remove tissue. Open prostatectomy is generally done if you have a very large prostate, bladder damage or other complicating factors. The surgery usually requires a short hospital stay and is associated with a higher risk of needing a blood transfusion.
Your follow-up care will depend on the specific technique used to treat your enlarged prostate.
Your doctor might recommend limiting heavy lifting and excessive exercise for seven days if you have laser ablation, transurethral needle ablation or transurethral microwave therapy. If you have open or robot-assisted prostatectomy, you might need to restrict activity for six weeks.
