Benign Prostatic Hyperplasia (BPH), formerly known as “prostate enlargement” and now referred to as “prostate hyperplasia”, is a common disease in older men. It mainly leads to lower urinary tract symptoms such as difficulty in urination (difficulty in urination, thinning of the urinary line, prolonged urination, waiting for urination, dribbling of urination, etc.), frequency and urgency of urination, hematuria, etc., and in severe cases, complete inability to urinate (urinary retention) as well as the formation of bladder stones, which seriously affects the quality of life of men. Prostatic hyperplasia is easily mistaken for prostatitis. Prostatitis is mainly seen in young men, causing urinary frequency and urgency, discomfort in the lower abdomen and perineum and other clinical manifestations, usually no obvious urinary difficulties; and prostate enlargement mainly occurs in men over 50 years of age; there are also a few patients with prostate enlargement combined with prostatitis.
