Microscopic spermatic cord surgery can take 2-3 hours or longer. This is because microscopic varicocele surgery is a more delicate surgical procedure that requires careful manipulation under a microscope. Because the microscope is usually magnified five to ten times, and the surgical instruments used are very precise and small, this operation is still difficult for the urologist. During the microscopic spermatic surgery, the arteries and veins of the spermatic cord need to be separated out separately, and then the veins of the spermatic cord need to be ligated separately, and the arteries and veins of the spermatic cord need to be skeletally separated, so the operation needs to be done carefully and without distraction to avoid hurting the arteries or veins. Therefore, it takes longer time to perform the surgery, but the microscopic spermatic cord surgery is very beneficial to the patient.
