The purpose of the preoperative talk is to let the patient and his family understand through this important talk: 1, the collective team spirit and role of surgical treatment. 2. to win the trust of the patient and his family in our medical services and medical standards; 3. to make the patient feel that he has enjoyed the most scientific and rational diagnosis and treatment of the disease; 4. the necessity of surgical treatment, and the risks; 5. to eliminate the fear of surgical risks, and to learn about our measures and ability to resist risks, and the limitations of our ability to resist risks. 6. the possibility of comprehensive and continuous treatment. 7. the late expressive and unpredictable nature of the effects of surgical treatment. From a medical point of view, surgical treatment is necessary. Why is it even emphasized here? Because there are some diseases that must be treated surgically from the disease itself, because we are treating the patient, so we have to consider the person’s age, general condition, family and socio-economic status when we consider the treatment program. For example, a patient in his 90s with prostatic hyperplasia, urinary retention, azotemia, and diabetes and coronary artery disease. The disease itself requires prostate surgery, but the patient’s age and general condition do not allow for surgical treatment, and only simple catheterization or cystostomy can be performed. This means that the risk of surgery is higher than its necessity. There are times when the necessity of surgery outweighs the risk. For example, a young middle-aged man was found to have a small kidney cancer during physical examination, and the patient did not have any symptoms. Many patients and their families do not always understand the relationship between the necessity and the risk of surgery, or even misunderstand it.
