GreenLight™

Overview

GreenLight™ Laser Therapy is a minimally invasive treatment option that combines the effectiveness of the traditional surgical procedure known as transurethral resection of the prostate (TURP) with fewer side effects. 1 The GreenLight laser system delivers the ultimate BPH solution – free from urinary symptoms, free from compromise, free to go!

GreenLight is suitable for most patients with an enlarged prostate. With nearly 500,000 procedures performed worldwide, the GreenLight procedure is creating a new standard of care — a standard that offers freedom from enlarged prostate symptoms .

Most patients return home a few short hours after the GreenLight procedure and can return to normal, non-strenuous activities within days.

Advantages of the GreenLight Laser Therapy treatment may include:

  • Rapid urine flow improvement 1
  • Quick return to normal activities 2
  • Virtually bloodless procedure 3, 4
  • Less than 1% reported cases of erectile dysfunction 5
  • Less than 24 hours of catheterization in most cases 3, 4
  • Outpatient procedure in otherwise healthy patients 2
  • Long-lasting symptom relief 3

How it Works

GreenLight™ Laser Therapy uses laser energy to remove enlarged prostate tissue. This results in an open channel for urine to flow through, but with less risk of the sexual and other side effects that are common with TURP. 1, 2

A small fiber is inserted into the urethra through a cystoscope. The fiber carries laser energy which removes enlarged prostate tissue. Natural urine flow is rapidly restored and urinary symptoms are quickly relieved in most patients.

The Procedure

GreenLight™ Laser Therapy can be performed in a hospital outpatient center or an office-based surgical facility. Typically no overnight stay is needed. However, in some cases when a patient travels a long distance, has other medical conditions to consider or is in frail condition, an overnight stay may be recommended.

Most patients return home a few short hours after the procedure, and can return to normal non-strenuous activities within days. 1, 2, 3

When symptoms begin to interfere with your lifestyle, it’s time to consider treatment choices. Understanding your options will help you make the right choice for your desired outcome and lifestyle needs. Therapy selection is a decision between you and your physician. Each option has advantages and disadvantages that should be explored in detail. Discuss this information with your urologist.

Your doctor may recommend prescription drugs to reduce the symptoms of your enlarged prostate. Drug therapies are safe and effective, but they can be expensive and do not work for all men. They also may have unpleasant side effects like dizziness, nasal congestion and sexual side effects. 1 Surgery is an option for some men whose symptoms have progressed or have other related urinary tract complications. But surgery requires a hospital stay as well as a lengthy recovery time. 1, 2

Laser therapy provides another alternative. GreenLight™ Laser Therapy gives physicians the ability to treat mild to severe enlarged prostate (BPH) symptoms. The procedure is suitable for most patients with enlarged prostate, including men who are not candidates for surgery and those who are on anti-coagulation therapy.
