Prostate Enlargement 

PROSTATE ENLARGEMENT: Most prostatic enlargement is due to benign prostatic hyperplasia (BPH), a problem that bothers men increasingly with advancing age. The process of BPH generally begins in a man’s 30s, evolves very slowly and usually causes symptoms only after he has passed the half-century mark.
In BPH the normal elements of the prostate gland grow in size and number. Their sheer bulk may compress the urethra which courses through the center of the prostate and impedes the flow of urine through the urethra from the bladder to the outside. The urethral compression leads to urine retention and the need for frequent urination. If severe enough, complete blockage can occur.
BPH is very common. Half of all men over 50 develop symptoms of PBH, but only 10% need medical or surgical intervention.
