If the internal diameter after varicocele surgery is only mildly widened and not extensive, and there is no other adverse reaction, it is considered normal. This condition is more common in the short term after surgery, and after a period of recovery, the internal diameter will gradually narrow.
However, if the degree of widening of the internal diameter after varicocele surgery is more serious, and the internal diameter cannot be narrowed down to the normal range by itself after a period of recovery, then it is considered abnormal. It may be due to the failure of the surgery or the weakening of the wall of the spermatic vein after the surgery.
After varicocele surgery, you should go to the hospital for regular checkups. If the internal diameter can not be reduced and accompanied by other symptoms, you need to consult a doctor in time to avoid affecting the quality of your sex life and fertility.
