What is GreenLight Laser Therapy?

GreenLight Laser Therapy has helped over 900,000 men worldwide.

Lasers are now used in many areas of medicine, including eye and cosmetic surgery. They are also used to treat an enlarged prostate.

During the GreenLight procedure, the tissue blocking your prostate is rapidly heated and vaporized. Natural urine flow is rapidly restored in most patients.

Typically, the procedure is performed as a same-day surgery. Many patients can go home without a urinary catheter. An overnight stay may be recommended for some patients.

Alternative Treatment Options

Typically, medicines are first used to treat an enlarged prostate. However, sometimes drugs don’t provide enough symptom relief. Or the side effects can be bothersome. Drugs can be expensive. Or there may be other reasons medical therapy for BPH isn’t right for you.

Transurethral Resection of the Prostate (TURP)

This procedure involves use of a heated wire to cut tissue from the prostate and has been used to treat an enlarged prostate for years.

Open Surgery

This procedure involves removal of the inner part of the prostate through an incision made in the abdomen.

Other Types of Lasers

In addition to GreenLight Laser Therapy, other systems remove enlarged prostate tissue through the use of high-energy lasers. Clinically documented laser therapies have become a viable treatment option.

Transurethral Microwave Therapy (TUMT)

In this therapy, a microwave antennae mounted on a catheter is used to heat the prostate and open up the blockage.

Advantages of GreenLight Therapy

Compared with traditional surgical options, GreenLight Laser Therapy is associated with:

  • Significantly less chance of severe blood loss6
  • Same-day surgery in most cases7
  • Significantly faster recovery in typical cases for the following:
    • Shorter hospital stay
    • Shorter catheterization time
    • Less bleeding
  • Comparable risks and outcomes

Hospital length of stay and time with a urinary catheter are typically shorter with the GreenLight procedure than TURP.

During the Procedure

The following is intended as a general overview. Your experience may differ. Please talk to your doctor about potential risks and questions you may have about the procedure.

Greenlight During Procedure

Before Treatment

Before treatment begins, you may be asked to empty your bladder.


  • You will then be brought into the procedure room and moved to the treatment bed where you will lie on your back. Your doctor may give you medication to help you relax.
  • The procedure is typically performed under general anesthesia. This means that you will be asleep during the procedure. A different type of anesthesia may be used, depending on the treatment center.


  • Once the anesthesia takes effect, your doctor will insert a small scope into your urethra. The scope allows your doctor to see the inner surfaces of the urethra, prostate and bladder.
  • After the scope is in place, your doctor will advance the laser device through the scope to the location of the enlarged prostate tissue.
  • Your doctor will then vaporize the prostate tissue that is obstructing urine flow. Dead tissue that is not immediately vaporized will be passed naturally in your urine during the first few days after your surgery.
  • A temporary urinary catheter may be placed at the end of the procedure to let urine drain from your bladder.
Greenlight After Procedure

After the Procedure

People typically go home within a few hours after the procedure. You should arrange for a ride home.

If a urinary catheter was placed in your bladder at the end of the procedure, it will typically be removed within 24 hours. However, some patients may require a catheter for a longer time.

Most patients experience very rapid relief of symptoms and a dramatic improvement in urine flow. This usually occurs within 24 hours of the procedure. Your experience may differ. Your doctor will provide you with specific discharge instructions and information on signs and symptoms that may require further medical attention.

You may experience mild discomfort such as slight burning during urination and see small amounts of blood in your urine for a week or so. Also, depending on the condition of your bladder, you may experience greater frequency and urge to urinate. This will likely resolve over time.

Usually, you can return to your everyday activities within a short time after the GreenLight procedure. If you have any questions, ask your doctor.

Every surgical procedure may have risks. The same is true for GreenLight™ Laser Therapy.

The most common risks include:

  • Hematuria – Blood in the urine
  • Irritation of the bladder – Results in frequent and/or urgent need to urinate
  • Irritation of the urethra – Frequent urination, burning sensation
  • Retrograde ejaculation – Semen during sexual climax travels backward to the bladder rather than exiting through the penis

At doctor’s instruction, some patients taking blood-thinners can be treated with GreenLight Laser Therapy without stopping their medicines.
