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.
