You will have to take 2-3 follow-ups after undergoing AVF surgery for dialysis. The first follow-up will be recommended within 7-10 days to see if the body is healing properly. The second follow-up will be done after 3-4 weeks to ensure that the fistula is working and there are no complications. When the recovery is complete, the final follow-up will take place after 6 weeks to check whether the fistula has matured or not.
