Laser Prostate Treatment for BPH
What is GreenLight™ Laser Therapy?
GreenLight™ Laser Therapy is a procedure performed with a small fiber that is inserted into the urethra through a cystoscope. The fiber delivers high powered laser energy which quickly heats up the prostate tissue, causing the tissue to vaporize. This process is continued until all of the enlarged prostate tissue has been removed. Natural urine flow is rapidly restored and urinary symptoms are quickly relieved in most patients.

GreenLight™ Laser Therapy combines the effectiveness of the “gold standard” transurethral resection of the prostate (TURP) surgical procedure with fewer side effects. The result is a wide open channel for urine flow to pass through, but with fewer risks of side effects, including erectile dysfunction and bleeding, common with TURP.
GreenLight™ Laser Therapy is generally performed on an outpatient basis so no overnight stay is needed.
What to Expect During A GreenLight™ Laser Therapy Treatment
Each patient is different, therefore treatment procedures may vary. Below is a general description of the procedure and what to expect:
- Before treatment your physician may give you medication to help you relax during the procedure.
- Other medications that your physician may give you are to avoid infections.
- You may be asked to empty your bladder.
- You will be brought into the procedure room and moved to the treatment bed where you will lie on your back. You will be provided anesthesia that will allow you to sleep through the entire procedure.
- Depending on the treatment center, other types of anesthesia may be used, including spinal block or pudendal block.
- Once you are asleep or the anesthesia block takes effect, your physician will insert a cystoscope through the urethra.
- The laser fiber is introduced through the cystoscope and advanced into the urethra at the location of the prostate.
Since this is an outpatient procedure, you will typically go home within a few hours after treatment. You should have someone drive you home after the procedure. A catheter is placed in your bladder at the end of the procedure which typically stays in several days.
Most patients experience very rapid relief of symptoms and a dramatic improvement in urine flow. This typically occurs within 24 hours of the procedure. However, medical history, health condition and other factors can influence treatment recovery.
