Three grades of varicocele need to be differentiated according to palpation, visualization and the results of Vakalva test, i.e. Grade I, Grade II and Grade III. 1. Grade I: The varicose vein is not obvious on palpation, but can be detected on palpation after the Valsalva test, which involves holding the breath and increasing the intra-abdominal pressure. 2. Degree II: The manifestation is normal in appearance, and the varicose vein can be palpated when standing normally, but the varicose vein cannot be detected by visual examination alone. 3.Ⅲ degree: the patient can clearly see the dilated veins in the skin of the scrotum when standing up, and palpation can also clearly feel the earthworm-like veins in the shape of a mass. Varicocele is a vascular disease, related to venous valve insufficiency, venous return obstruction and other reasons. It is usually asymptomatic, and in severe cases, symptoms such as enlargement of the scrotum, sensation of swelling and hidden pain may occur. When patients are checked for the presence of varicocele, they should cooperate with the doctor for active treatment so as not to delay the condition.
