The length of hospitalization required for hemodialysis fistula surgery varies from individual to individual, usually ranging from a few days to several months. Hemodialysis fistula surgery is a relatively common surgery, some patients can usually be discharged in a few days if the fistula function is assessed to be good after surgery and there are no other complications after observation. If there is discomfort, bleeding, or infection in the fistula after the surgery, it is necessary to follow the doctor’s instructions, take active measures to protect the wound, and avoid aggravation of infection and bleeding, which may lead to longer hospitalization. If the condition is more serious, prolonged hospitalization may be required, which can last up to several months. Before being discharged from the hospital, patients are usually required to undergo blood flow observation. If the blood flow is normal and the fistula stoma remains open without causing the emergence of blood clots, the criteria for discharge can be met. Once discharged, the patient is also required to take active care under the guidance of a specialist and is advised to seek prompt medical attention if he/she feels unwell.
