Varicocele is one of the common diseases in young adults, mostly on the left side, with a prevalence of 10% to 23%, with varying degrees of scrotal drop, discomfort or infertility after marriage. Anyone with symptoms or semen abnormalities with infertility, excluding secondary lesions, requires surgical treatment. The traditional treatment of varicocele is open surgery, which has a long incision, requires more separation, takes a long time, and is prone to recurrence or continuation of varicocele if the high ligation is insufficient, which affects the efficacy. The laparoscopic ligation of the spermatic artery and the testicular artery can still survive after the high ligation, which will not cause testicular atrophy, and there is no need to separate the levator muscle, which avoids damage to the vas deferens arteriosus, external spermatic vessels and vas deferens, and is conducive to the establishment of lateral branch circulation after surgery. The laparoscope can ligate the spermatic vessels from 2 to 3 cm above the internal ring or above here, where the spermatic veins are usually confluent into 1 or 2 branches, so it is not easy to miss the ligation and the recurrence rate is greatly reduced. Moreover, the spermatic veins are clearly visible after the laparoscope enters the abdominal cavity, and with the magnifying effect of the laparoscope, the anatomy is clearer, and there is no need to separate the spermatic arteries and veins during the operation, and the blood vessels are not cut, so the operation is easier, with minimal bleeding, and the operation time is greatly shortened. Laparoscopic high level spermatic vein ligation has many advantages such as less trauma, less pain, good cosmetic effect of incision, fast recovery, low recurrence rate, etc. Moreover, it can deal with bilateral lesions without increasing the incision, and its superiority has been accepted by the majority of doctors and patients and widely carried out.
