Green Light Laser Prostate Treatment

Green light laser therapy is a procedure that uses a special high-energy laser for vaporizing extra prostate tissue. It is less invasive than traditional methods of prostate surgery, which involve cutting out the prostate tissue. Because the tissue is vaporized rather than cut out there is generally less blood loss.


  • Any allergies you have.

  • Any medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medication.

  • Previous problems you or members of your family have had with the use of anesthetics.

  • Any blood disorders you have.

  • Previous surgeries you have had.

  • Medical conditions you have.


Generally, green light laser prostate treatment is a safe procedure. However, as with any procedure, complications can occur. Possible complications include:

  • Urinary tract infection.

  • Erectile dysfunction (rare).

  • Dry ejaculation—Semen is not released when you reach sexual climax.

  • Scar tissue in the urinary passage.


  • Your health care provider may discuss medicines you are taking and may advise you to stop taking specific ones.

  • You may be given antibiotics to take as a precaution against bacterial infection.

  • Do not eat or drink anything for 8 hours before your procedure or as directed by your health care provider. You may have a sip of water to take any necessary medicines.


Depending on the size and shape of your prostate, the procedure may take 30–60 minutes. You will be given one of the following:

  • A medicine that makes you go to sleep (general anesthetic).

  • A medicine injected into your spine that numbs your body below the waist (spinal anesthetic). Sedation is usually given with spinal anesthetic so you will be relaxed.

A tube containing viewing scopes and instruments will be inserted through your penis so that no cuts (incisions) are needed. A thin fiber is put through the tube and positioned next to the excess prostate tissue. Pulses of laser light come from the end of the fiber and are projected onto the excess tissue. The laser beam is absorbed by your blood, which becomes hot enough to vaporize the excess prostate tissue. This laser beam will seal off the blood vessels, decreasing bleeding. The tube with the viewing scopes, instruments, and thin fiber will be removed and replaced with a temporary catheter.


After the surgery, you will be sent to the recovery room for a short time. Depending on factors such as the amount of prostate tissue vaporized, the strength of your bladder, and the amount of bleeding expected, the catheter may be removed. Generally, overnight stay is not needed and you will be sent home on the same day as the procedure. You may be sent home with elastic support stockings to help prevent blood clots in your legs.
