Benign prostatic hyperplasia (BPH) is an enlargement of the prostate. The prostate is usually a walnut-sized gland located at the neck of the bladder. It surrounds the urethra, a tube that carries urine from the bladder to the outside of the body.
An enlarged prostate puts pressure on the urethra and can make it difficult for urine to pass. Eventually, the urethra may become completely closed off.
