Benign prostatic hyperplasia
- Anatomy of prostate
- Histology of prostate
- Development of prostate
- prostate arises from
a budding collection
of tissue in the
urogenital sinus.
- The prostate develops from
epithelial outgrowths form
the prostatic segment of the
urethra that grows into the
surrounding mesenchyme.
- This outgrowth and
branching start at week 10
during embryo growth; by
week 12, there are 5
groups of tubules that
form the lobes of the
prostate.

- PSA
- produced by the prostate gland.
- is a 33-kd protein consisting of a
single-chain glycoprotein of 237 amino
acid residues, 4 carbohydrate side chains,
and multiple disulfide bonds.
- produced by the prostate gland.

- BPH Pathophysiology
- Proliferation of both epithelial and stromal elements
- Both androgens and estrogens may play a role
- Relative increase in estrogens in older men
may increase DHT receptors in prostate

- screening beins at the agae of 50 with DRE and PSA
- Decreased % free PSA suggest cancer
- Biopsy is required to confirm
