Severity of varicoceles can be divided into three degrees Mild: not obvious on palpation, but can be detected by Valsalva method, i.e., hidden varicose veins can be seen when the child is standing with the mouth and nose closed, deep inhalation and abdominal pressure increased by the doctor’s hand pressing on the abdomen. Moderate: There is no obvious abnormality in appearance, but dilated veins can be felt on palpation. Severe: The varicose veins look like a mass of earthworms and are obvious on palpation and visualization. Mild: stagnant veins in the spermatic cord without spontaneous reflux. Moderate: intermittent reflux in the spermatic veins. Severe: there is persistent reflux. What are the risks of varicocele? Varicocele usually has no obvious symptoms, and only if it is more serious, it will be uncomfortable. However, varicocele can lead to long-term sustained damage to testicular tissue, which is one of the important causes of male infertility, and some studies show that infertility caused by varicocele accounts for 21% to 41% of male infertility, which shows the strong killing power. And most of the infertility caused by varicocele cannot be restored to normal fertility after surgery, no matter which method is used to treat varicocele. So varicocele should be taken seriously enough. How to treat varicose spermatocele? When should it be treated? At what level of varicocele should surgery be performed? How to choose the surgical procedure? The most effective treatment for varicocele in children is surgery, which is a high level ligation of the internal spermatic vein. The long-term presence of varicocele can lead to impaired testicular function, so surgery should be performed as soon as possible when varicocele is found to be moderate or above. The vast majority of children with varicocele are already at a moderate or severe level at the time of detection. In recent years, we have adopted laparoscopic minimally invasive treatment for varicocele, which is less invasive, faster recovery, and has very small postoperative scars, and traditional surgery has been largely abandoned.
