Benign Prostatic Hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland. It is a common urological disorder in men over 50 years of age. This enlargement of the prostate causes the urethra, the tube that passes the urine out of the penis, to be squeezed and narrowed. This block the passage of urine out of the bladder and more pressure is needed to pass urine.
The bladder starts to contract even when it is not completely full, and eventually loses its ability to empty itself. The symptoms of Benign Prostatic Hyperplasia are associated with the narrowing of the urethra and the incomplete emptying of the bladder.
