Green Light Laser Prostate Treatment

The prostate is a gland of the male reproductive system. Most men older than 50 years have some enlargement of the prostate (benign prostatic hyperplasia). As the prostate enlarges, men find it increasingly difficult to pass urine. Medicines to shrink the size of the prostate can be used. If these medicines are not effective, surgery may be needed. Traditional surgery performed for benign prostatic hyperplasia is known as transurethral resection of the prostate. This surgery requires a hospital stay and may be associated with certain complications.

Green light laser therapy is a new procedure that uses a special high-energy laser for vaporizing extra prostate tissue. It is a minor procedure compared with traditional surgery. It limits the chance of destroying the surrounding tissue. Also, it can be done under spinal or general anesthesia. Green light laser therapy may provide longstanding and almost immediate relief of a patient's symptoms.

A laser is inserted into your prostate through your urinary passage (urethra) using a tube with an optical device at the end (endoscope). This helps your surgeon to clearly see the affected area. The green light laser applies high-power laser energy to the affected tissue until it is vaporized. This procedure is continued until all the affected tissue is removed. The loss of blood is minimal. There is little damage to the surrounding tissues. The entire procedure may take about 60 minutes. It is rare to require a catheter for longer than 2 hours after the procedure. You may be allowed to go home on the same day. Overnight stay is rarely needed.
