I. Symptoms: Benign prostatic hyperplasia is a common disease in middle-aged and older men, with about half of men over the age of 50 experiencing clinical symptoms. The enlarged prostate squeezes the urethra, leading to a series of symptoms of urinary disturbance, such as frequent urination, thinning of the urine line, incomplete urination and other urinary disturbances. These symptoms seriously affect the patient’s quality of life, and untimely treatment can lead to many serious complications (such as acute urinary retention, stones, renal insufficiency, etc.) and can even endanger the patient’s life. Second, complications: 1, easy to induce patients with hypertension, coronary heart disease, heart failure, cerebrovascular disease and a series of other diseases. 2, cause bladder forced urinary muscle hypofunction and renal function endangerment, and a series of systemic uremic manifestations, and ultimately the formation of renal failure. 3, the formation of urinary incontinence, urinary retention and bladder stones. 4, prostate hypertrophy can cause infertility. 5, prostate enlargement affects sexual function, causing impotence and premature ejaculation. The mechanism of action is to selectively block the alpha1A receptors on the urethra, bladder neck and prostate smooth muscle and inhibit their contraction to improve symptoms such as difficulty in urination caused by prostate enlargement. 2, Chinese medicine and pollen preparations: the main ones are prostate health, prostate pass. The 5α-receptor reductase inhibitor research has proven that 5α-receptor reductase in the prostate, prompting the conversion of testosterone to dihydrotestosterone, thus causing hypertrophy of the prostate, its inhibitors can make the prostate hypertrophy of tissue degeneration, apoptosis, hypertrophy of the gland shrinkage, to improve urinary difficulties and so on. The representative drugs are Epradex and Finasteride (Paulownia). (2) Surgery Although there are many drugs for prostate hyperplasia, the underlying causes and pathogenesis of prostate hyperplasia are not yet fully understood, so the main focus of drug therapy is to improve and relieve symptoms, and surgery should be considered promptly for those who have severe symptoms and whose treatment by drugs and other conservative means is ineffective. 1, open prostate removal 2, transurethral resection of the prostate (TURP): including transurethral monopolar prostate resection, the latest transurethral bipolar plasma vaporization electrosurgery
