A new method has been added to the treatment of varicocele. Recently, the Department of Urology of our hospital successfully performed microscopic varicocele ligation for a patient with varicocele. The patient was a young man, 25 years old, admitted to the hospital with intermittent left scrotal pain for 4 days. On examination, he could see a tortuous and dilated venous mass in the left scrotum, a thickened spermatic cord, a softer testicle and a smaller volume. The diagnosis of varicocele was clear, and the symptoms affected life with testicular changes. Active surgical treatment was recommended to improve the symptoms and prevent the testicular atrophy from worsening. At present, there are four types of surgical treatments for varicocele: traditional open surgery, laparoscopic surgery, microscopic surgery and spermatic vein interventional embolization treatment. Some studies have shown that the traditional open surgery is very traumatic and has a high recurrence rate, so this procedure has been gradually abandoned. Laparoscopic surgery requires general anesthesia, is more expensive, and cannot separate the spermatic artery and lymphatic vessels, and has more postoperative complications. In contrast, microscopic can easily ligate all the draining veins except for the vas deferens, preserving the arteries, nerves and lymphatic vessels, significantly reducing complications such as recurrence and testicular atrophy, with a low recurrence rate, significantly improving semen quality and increasing the conception rate. Microscopic high level ligation of the spermatic veins has become one of the main procedures for the treatment of varicocele in Europe and America. This patient underwent successful microscopic spermatic vein ligation under intravertebral anesthesia, and the surgical incision was only 50px. He was able to move and eat normally 6 hours after the operation, and was discharged from the hospital the day after the operation, which was well received by the patient.
