Prostate laser surgery
Prostate laser surgery is used to relieve moderate to severe urinary symptoms caused by an enlarged prostate — a condition known as benign prostatic hyperplasia (BPH).
During prostate laser surgery, your doctor inserts a scope through the tip of your penis into the tube that carries urine from your bladder (urethra). The prostate surrounds the urethra, and if the prostate is enlarged, it restricts urine flow from the bladder. A laser passed through the scope delivers energy that shrinks or removes excess tissue from the prostate that is preventing urine flow.
Lasers use concentrated light to generate precise and intense heat. There are several different types of prostate laser surgery, including:
- Photoselective vaporization of the prostate (PVP).A laser is used to melt away (vaporize) excess prostate tissue and enlarge the urinary channel. This procedure is generally used to treat prostates that are mild to moderately enlarged.
- Holmium laser ablation of the prostate (HoLAP).This procedure is similar to PVP but uses a different type of laser.
- Holmium laser enucleation of the prostate (HoLEP).A laser is used to cut and remove the excess prostate tissue that is blocking the urethra. Another instrument is then used to cut the prostate tissue into small pieces that are easily removed. HoLEP can be an option for men who have a severely enlarged prostate.
