GreenLightTM Laser Therapy

What is GreenLightTM Laser Therapy?

GreenLightTM Laser Therapy combines the effectiveness of the “gold standard” transurethral resection of the prostate (TURP) surgical procedure with fewer side effects. Several studies have shown comparable outcomes between the two procedures.1 During the GreenLightTM procedure, the physician uses a laser to remove the excess prostate tissue. The result is a larger channel for urine flow to pass through. Removing the excess tissue eliminates most lower urinary tract symptoms.

The criteria for selection of patients for GreenLightTM Laser Therapy are the same as those for TURP, so any patient who would benefit from TURP may also be a candidate for GreenLightTM.

GreenLightTM Laser Therapy can be performed in a hospital outpatient center, surgical center, or specially equipped physician’s office. The patient is usually put under general or spinal anesthesia for the duration of the treatment. 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.

How does GreenLightTM work?

GreenLightTM Laser Therapy is a procedure performed with a small fiber that is inserted into the urethra through a cytoscope. The fiber delivers high-powered laser light. Blood inside the enlarged prostate tissue instantly absorbs the laser light, heating the tissue and causing it to vaporize. This process is continued until all of the enlarged prostate tissue has been removed.2

GreenLightTM has been acclaimed for its ability to precisely vaporize tissue without causing damage to underlying structures.3 Natural urine flow is rapidly restored and urinary symptoms are quickly relieved in most patients—all with minimal blood loss, minimal postoperative discomfort, and a short hospital stay.3
