Prostatic hyperplasia is a common and frequent disease in elderly men. According to literature statistics, the incidence rate of prostate hyperplasia in men over 41 years old is 30.5%, and its incidence rate increases gradually with age, which has become one of the major diseases jeopardizing the health of elderly men, bringing great pain to many patients and seriously affecting the quality of life of elderly friends. Prostatic hyperplasia is characterized by frequent urination at the beginning of the disease, especially at night, not much urine each time, with the feeling of incomplete urination, and at the same time or subsequently appeared to be waiting for urine, prolonged urination time, thin urine line, short range, end of urination urine dribbling, at this time, if not treated in a timely manner, the disease will be gradually aggravated, urinary retention, urinary incontinence, easy to lead to infections, bladder stones, hydrocephalus, and finally evolved into uremia. It is worth emphasizing that prostate hyperplasia is a relatively slow process, often several years or more than ten years. Many elderly people have a kind of wrong understanding that weak urination and prolonged urination time is nothing more than a normal phenomenon of the elderly. The alertness is not high, and they suffer in silence. It is not until urinary retention occurs and they are unable to urinate that they come to seek medical attention. By this time, it is already in the later stages of the disease, and the loss of kidney function can no longer be restored. There are two ways to treat prostate hyperplasia: medication and surgery. Since the cause of prostate hyperplasia is not very certain, there is a lack of therapeutic drugs that target the cause. For early stage and patients who cannot tolerate surgery, medication is usually used. The treatment can relieve symptoms to a certain extent at the initial stage, but the long-term effect is not satisfactory. Surgical treatment is best for patients with prostate enlargement above moderate hyperplasia, especially those with increased residual urine, bladder stones, bleeding, urinary retention, and urinary incontinence; surgical treatment for prostate enlargement has a satisfactory and long-lasting effect. With the advancement of medicine, the surgical methods of prostate enlargement have changed significantly, from the initial traditional open surgery to the various transurethral resection of the prostate today, such as: transurethral resection of the prostate with electrosurgery, transurethral resection of the prostate with laser, vaporization electrosurgery of the prostate, and transurethral resection of the prostate with plasma. Transurethral resection of the prostate has long been the gold standard of surgical treatment of prostatic hyperplasia, and in recent years the emergence of transurethral resection of the prostate vaporization electrocision, plasma resection due to the traditional transurethral resection of the prostate electrocision and laser resection of the advantages of bleeding less than the transurethral resection of the prostate electrocision, the efficiency of laser resection to be higher, has a safe, less traumatic, the surface of the body without incisions, postoperative recovery, hospitalization time is fast, fewer complications and so on. It has the advantages of safety, small trauma, no incision on the body surface, fast postoperative recovery, short hospitalization time, and fewer complications.
