Varicocele is a common urological condition that can be found in 15-29% of the male population. The stagnant blood in the varicocele and the long-term increase in testicular temperature can cause changes in the pathology and physiological structure of the testes and epididymis, which can lead to male infertility. In mild cases, there may be no symptoms, but in more severe cases, there may be discomfort and even pain in the scrotum, and there may be back pain when standing for a long time, which can be relieved by lying down and resting. If the varicocele is severe, the patient can see a worm-like varicose vein mass in the scrotum when standing. In mild or occult varicocele, holding the patient’s breath to increase abdominal pressure may make the varicocele visible or palpable. There are no medications available to treat varicocele, and several surgical procedures are commonly used to treat varicocele, including conventional open surgery, laparoscopic surgery, and microscopic surgery, each of which is effective when performed skillfully. However, with the rapid development of minimally invasive technology in recent years, the application of laparoscopic high ligation of spermatic veins has been widely appreciated and has become an important surgical method for the treatment of varicocele, and with the application of single-hole laparoscopy, it leaves almost no scars, but it needs to be performed in a regular hospital with good technical conditions.
