Final answer:
Prostatism is the term for the obstructive and irritative symptom complex caused by benign prostatic hypertrophy, which can lead to various urinary tract symptoms and is treated through medication or surgery.
Step-by-step explanation:
The obstructive and irritative symptom complex caused by benign prostatic hypertrophy is termed prostatism. This condition is a result of benign prostatic hyperplasia (BPH), an abnormal enlargement of the prostate gland that can lead to the constriction of the urethra. As a consequence, patients may experience symptoms like a frequent and intense urge to urinate, a weak urinary stream, and sensations of incomplete bladder emptying. Treatments for BPH are designed to alleviate these obstructive symptoms, helping urine to flow more normally. Treatment options range from medication for mild to moderate symptoms to surgical removal of prostate tissue for more severe cases.
