In men over 50 enlargement of the prostate (benign prostatic hypertrophy) is common. Sometimes the result is pressure on the urethra and bladder, which interferes with urination, precipitating urinary retention and kidney disease. Balloon dilatation of the urethra and medication with alpha blockers, finasteride (Proscar), and saw palmetto extract (an herbal supplement) have joined traditional surgical removal of the prostate (prostatectomy) as therapies. See also prostate cancer , prostatitis .
