In recent years, with the maturity of percutaneous nephrolithoscopy technology, for single stones in the renal pelvis and upper ureteral stones can be done by tubeless percutaneous nephrolithoscopy, without leaving a nephrostomy tube after the operation, and the patient has less postoperative pain and faster recovery. This is a case of a patient with a single stone in the left kidney Impotence is a very common disease and a disease that can be treated and cured. However, it is not easy to obtain satisfactory treatment results; the ideal treatment results depend both on the correct treatment method adopted by the doctor and on the patient’s proper understanding of the diagnosis and treatment method. 1. What is the goal of impotence treatment? The goal of impotence treatment seems to be a very simple question, but in fact not many people really understand it. The exact cause of most impotence is not clear due to current diagnostic and therapeutic technical conditions, therefore, it is not advisable to blindly pursue etiological treatment, while improving impotence symptoms so that the patient can satisfactorily complete sexual life is still the goal of treatment. 2. My examination is fine, so why do I still suffer from impotence? Due to the current technical conditions, many tests cannot be performed clinically. For example, current research has found that many impotent patients have genetic defects. In patients with genetic defects, the blood vessels in the cavernous body of the penis do not easily expand and fill with blood during sex, so they are not hard during intercourse. There are also patients with neurological dysfunction, such as good erections at night, but not normal erections when awake, which is related to excessive inhibition of erection by the central nervous system. When encountering such patients the doctor can only make a diagnosis by clinical reasoning and cannot provide an objective basis for examination. This is a common reason why such impotent patients are found to have no abnormal test results when they go to the hospital for examination. 3.How long is the course of impotence treatment? The course of impotence treatment varies from person to person. Some people can be cured after a period of treatment, while others need to take drugs for a long time, mainly because of the cause of impotence. Generally speaking, impotence caused by congenital factors, or secondary to age, or due to certain chronic diseases (such as diabetes, hypertension or arteriosclerosis, etc.) often requires long-term medication. 4.Can impotence be removed from the root? Curing impotence is the common goal of both doctors and patients. However, because the causes of impotence are complex, it is sometimes difficult to talk about curing and removing the root cause. Impotence is mostly caused by vascular neurological insufficiency of the penis, which can be caused by congenital genetic defects, metabolic abnormalities (such as elevated or high blood sugar and lipids), or other medical conditions (diabetes, hyperthyroidism, other neurological diseases, etc.). It is difficult or impossible to eliminate these primary causes, so it is sometimes unrealistic to pursue the root cause. 5. How to choose the right drug therapy? There are many types of medications available for the treatment of other diseases such as hypertension, diabetes, and so on. However, there are fewer types of drugs that can effectively treat impotence, so it is really important to choose the right drugs and use them correctly when treating impotence. ①Dosage is individualized. For example, Viagra and so on, not everyone’s dose is one tablet. Young people or people with mild symptoms can take a smaller dose, starting with a small dose (half or a quarter of a tablet) orally, as long as it is effective, but if the effect is not good, the dose should be gradually increased. Some doctors recommend taking the drug every day before sexual intercourse, but my own experience is that most people can take it orally before sexual intercourse, there is no need to eat every day, so as to save money and help to avoid reducing the effect of drug resistance. The specific course of treatment is different for each person and depends on the condition. The causes of impotence are complex, so improving the symptoms is the foundation, and comprehensive treatment is beneficial to the overall recovery. The comprehensive treatment includes the combination of Chinese and Western medicine, psychological and behavioral counseling, etc. 6.Who needs to choose surgical treatment? Patients often ask about surgery for impotence. Since the treatment effect of impotence not only depends on the drug efficacy itself, but also involves complex psycho-psychological problems, therefore, ① for unsatisfactory or ineffective drug treatment, or ② for impotence caused by psycho-psychological factors, if the treatment effect is not good or ineffective, it is recommended to make up your mind as soon as possible to actively take surgery
