Since the 1840s, scientists and clinicians have been researching and exploring the treatment of varicocele. Overall, it has gone through the process from the initial conservative treatment, medication, and sclerotherapy to the current embolization and surgery. So far, scientists and clinicians around the world generally agree that surgery is the best treatment method with the best results. In fact, surgery also goes through a long development process. Initially, it was high ligation, which is a very classic surgical method and has cured a large number of patients, however, this procedure is operated under direct vision with the naked eye because it is an open surgery, and the arteries and lymphatic vessels of the spermatic cord are very small, and in most cases it is difficult to identify them with the naked eye, so it is easy to ligate the arteries and lymphatic vessels by mistake, and testicular atrophy and scrotal edema easily occur after surgery. The rate of recurrence after surgery is also high due to the high location. In the late 20th century, due to the development of laparoscopy, the use of laparoscopy greatly improved the quality of surgery and reduced the incidence of postoperative complications, but because this type of surgery requires access to the retroperitoneum and general anesthesia, it inevitably increases the risk of anesthesia and surgery, and the cost is also more expensive, generally more than 10,000 yuan. Also in the 1990s, the development of microscopic technology has greatly improved the quality of varicocele ligation surgery, because this type of surgery is performed in a lower position with superficial skin opening, only 2-3 cm long and 3-4 cm deep, without entering the abdominal cavity, which generally does not hurt the intestine, which greatly reduces the risk of surgery, and because it is operated under a microscope (magnification 5-10 times), so that the lymphatic vessels and the lymphatic tracts are not damaged. Because the operation is performed under a microscope (magnification 5-10 times), the lymphatic vessels and arteries can be seen very clearly, so that misligation can be avoided, which greatly reduces the complications of the operation, and the surgical results are better than all previous surgical procedures, and the cost is much lower than that of laparoscopic surgery. From my own experience, I have been doing microscopic varicocele ligation since June last year, and so far, there are more than 100 such patients who have recovered well from the surgery, and so far, there is no recurrence in the patients who usually come back for review after 3 months.
