Final answer:
Benign prostatic hyperplasia (BPH) causes an abnormal enlargement of the prostate gland, leading to constriction of the urethra and difficulty in urinating in elderly men.
Step-by-step explanation:
Hyperplasia of the prostate, a troublesome condition commonly seen in elderly men, constricts the urethra so that urination is difficult. Benign prostatic hyperplasia (BPH) is an abnormal growth of the prostate gland that affects many men as they age. The prostate surrounds the urethra and, when enlarged, it can impede urine flow. Symptoms may include a frequent need to urinate, weak urine stream, and feeling of incomplete bladder emptying. By 60 years, around 40% of men experience some level of BPH. Treatments range from medication for mild cases to surgery for severe instances.
Benign prostatic hyperplasia, or BPH, is an enlargement of the prostate gland occurring as men age. The prostate is integral to the male reproductive system and doubles in size during puberty. A secondary growth phase begins around age 25. When the prostate becomes enlarged, it can squeeze the urethra causing lower urinary tract symptoms. These include a constant and intense urge to urinate, weak urine stream, and a feeling that the bladder is not fully emptied.
