Scott PY - 2019 T2 - McGraw-Hill's NAPLEX® Review Guide, 3e AB - Benign prostatic hyperplasia (BPH) is an enlarged prostate gland. The prostate gland surrounds the urethra, the tube that carries urine from the bladder out of the body. As the prostate gets bigger, it may squeeze or partly block the urethra causing problems with urinating. The prostate begins to grow as men age, increasing the risk for BPH. Patients with BPH have increased smooth muscle tissue in the prostate containing α1-adrenergic receptors resulting in vasoconstriction and narrowing of the urethral lumen. Additionally, patients have physical obstruction symptoms resulting from an enlarged prostate.
