Among all men over the age of 40 years, in an age-dependent manner approximately 50% will develop histological hyperplasia or benign prostatic hyperplasia (BPH); of those, 50% will have bothersome lower urinary tract symptoms (LUTS), which may also be caused by other conditions; some will develop a significant enlargement of the prostate (EP), which can only exist in men with histological BPH; some will develop bladder outlet obstruction (BOO), which may also exist owing to causes other than BPH and EP. Treatment should take into consideration whether the patient has LUTS with or without EP and with or without BOO.
