1, the concept, incidence and age characteristics of geriatric prostatic hyperplasia The prostate is a male reproductive organ that increases in size with age under the action of sex hormones and a variety of genes and factors, causing clinical symptoms called prostatic hyperplasia. In foreign countries, about 1.7 million prostate enlargement patients go to outpatient clinics every year, and the cost of treatment for just a few of these inpatient surgery patients is as much as $30 billion per year, a heavy burden on society, families and patients. The incidence of prostatic hyperplasia histology gradually increases with age. the incidence is <10% for those under 40 years old, 20% for those 41-50 years old, 40% for those 51-60 years old, 70% for those 61-70 years old, 80% for those 71-80 years old, and more than 90% for those over 80 years old. Domestic studies show that the incidence of prostate enlargement is 20% for people aged 51 to 60 and 50% for those aged 61 to 70. The actual risk of acute urinary retention increases significantly with age in older men aged 70-79 years with a 10% incidence of acute urinary retention in 5 years, the larger the prostate volume, the higher the incidence of urinary retention. (2) Urinary incontinence After prostate enlargement, urine discharge is difficult, when the amount of urine retained in the bladder is large, so that the pressure of the bladder is higher than the resistance of the prostate gland involuntary outflow of urine, this situation is called filling incontinence. It mostly occurs at night after sleep and is a serious manifestation of prostatic hyperplasia. (3) Urinary tract infection Due to the obstruction of urine discharge, bacteria can easily remain and infection can occur. (4) Hematuria There are thick veins on the surface of the prostate gland after enlargement, and when the veins rupture during forceful urination, hematuria occurs. It can also be caused by prostate infection and bladder stones. (5) Internal and external hemorrhoids and inguinal hernia In order to discharge urine, many people force their abdomen to assist in urination, which increases abdominal pressure and causes internal and external hemorrhoids and inguinal hernia. (6) Bladder diverticulum When a large amount of urine remains in the bladder, the weak part of the bladder wall will bulge outward and form a bladder diverticulum when urination is exerted. A large amount of urine can remain in the bladder diverticulum, causing stones and tumors. (7) Bladder stones are caused by a large amount of residual urine and urine salt deposits after prostate enlargement. It can aggravate the difficulty of urination, cause hematuria and tumor. (8) Hydronephrosis A large amount of residual urine cannot be excreted and urine refluxes to the kidneys, causing hydronephrosis in both kidneys, which is the main cause of renal failure and infection. (9) Renal failure is the most serious complication of prostatic hyperplasia. 3. The impact of prostatic hyperplasia on patients' lives Patients suffering from prostatic hyperplasia have poor rest at night, reduced group activities, dare not go out, have to reduce water consumption and embarrassment in public bathrooms in their daily lives due to symptoms such as frequent urination, difficulty in urination and incontinence. Based on the fact that prostate hyperplasia is a benign and curable disease. It can affect the health of the patient.
