The postoperative recurrence rate is high after transinguinal spermatic vein high ligation. Prevention of postoperative recurrence has become the key to improve the surgical outcome of this disease. Varicocele recurrence is defined as:varicocele that recurs 6 months after surgery. The current clinical data shows that the recurrence rate of transinguinal internal spermatic vein ligation is as high as 25%, and the recurrence due to the missed testicular vein branches accounts for 68% of the total recurrence, while other methods also have different degrees of recurrence. The main reasons for recurrence are: 1) incomplete ligation and omission of the branches of the internal spermatic vein; 2) failure to cut off the internal spermatic vein after ligation; 3) existence of venous obstructive lesions: there are extensive anastomotic branches between the internal spermatic vein and the vas deferens vein and the external spermatic vein, and they gradually converge with the superficial inferior abdominal wall vein, the deep inferior abdominal wall vein, the internal pubic vein, the superficial external pubic vein and the superficial iliac vein in the soft tissue near the root of the scrotum and the superficial ring of the inguinal canal. There are extensive anastomotic branches between the superficial iliac veins and the inferior vena cava, the common iliac vein and the internal and external iliac veins after the ligation of the internal spermatic vein, which may cause the recurrence of varicocele; 5. The vascular spasm becomes thin and causes the omission; 6. At present, there is no unified consensus on the treatment of recurrent varicocele in China, but there are mainly the following: 1.Ligation of the lumbar trunk of the testicular vein below the renal vein through a straight incision in the lumbar back, the initial clinical application does have the advantages of good recent efficacy, light scrotal reaction and fast recovery of the patient, but the long-term effect of this procedure is under further observation. 2.Ligation of testicular vein through transverse incision on the umbilicus, which is currently used in foreign countries with good results. 3.Interventional embolization method: The use of sclerosing agent to embolize the lateral branch vein causing thrombosis is relatively simple and can reduce the recurrence rate, while the improvement of sperm count, sexual function and conception rate is the same compared with the ligation method. However, embolization is not possible or is not effective in patients in whom the returning venous vessels are not easily found or who have multiple small complex returning veins. Such cases 1 and 2 above are also powerless. Some studies have reported better results with the combination of ligation and embolization methods.
