Heart disease, high blood pressure and cerebrovascular disease history of threat to human health of major diseases, many older men are very important to the prevention of these kinds of disease and check. But they ignore the unique male organ – prostate disease, in fact almost all men over 50 have some degree of prostate enlargement. Benign prostatic hyperplasia is a long-term progressive disease process, which can be categorized into 3 stages according to the development of the disease and clinical symptoms. Stage 1: slow development of the disease The main symptom at the beginning is frequent urination, especially at night, the frequency of urination can be increased from 1 to 3 times to 4 to 5 times, which affects the sleep and rest of the elderly. Later on, it gradually appears that urination is not smooth, weak, the urine line is divided and the projectile is not far. Stage 2: Gradual aggravation The resistance of the posterior urethra increases, urinary frequency worsens, urination becomes more difficult, the urine line is thin and incomplete, and increased abdominal pressure is needed to help urinate. It takes longer time to urinate, and the bladder muscle is unable to expel the urine completely, so some of the urine remains in the bladder after each urination, which is called “residual urine”. Since the bladder can never be completely emptied, the accumulated urine can become infected, resulting in urinary pain, urgency, hematuria and interruption of urine flow. In addition, due to the impact of rest, physical exertion, resulting in excessive mental stress, can cause increased blood pressure, and in severe cases, can induce heart failure or cerebrovascular accidents. The third stage: the posterior urethral obstruction is more serious When urinating, it can not become a line, and it is dripping, and the residual volume of urine in the bladder is more than 500 ml, and there can be the phenomenon of “bedwetting” at night. The urethra dribbles urine involuntarily. When the outflow of urine is blocked and the pressure in the bladder increases, the kidneys and ureters will be affected, leading to kidney infection and acute pyelonephritis. If left untreated, it eventually affects renal function, and patients present with symptoms of chronic renal failure, and can eventually die of uremia. China has now gradually entered the elderly society, benign prostatic hyperplasia as a threat to men’s health of a common disease, must be correctly recognized, timely and effective treatment.
