What does it mean to have a renal dialysis fistula

Renal dialysis fistula is a procedure to establish a vascular access, such as arteriovenous endovascular fistula, for patients with end-stage renal disease before they undergo long-term hemodialysis.
The glomerular filtration and reabsorption functions of patients with end-stage renal disease are severely decreased, toxins, metabolic wastes and water can not be eliminated from the body, and edema, acidosis, hypertension, heart failure, nausea and vomiting, loss of appetite, pericardial effusion, shortness of breath, and renal anemia occur.
Patients with end-stage renal disease should have timely renal replacement therapy, including hemodialysis, peritoneal dialysis and kidney transplantation. Patients on long-term hemodialysis should have vascular access established in advance, and fistulas are needed to perform normal dialysis and maintain blood circulation in the body. Currently, anastomosis of the radial artery and cephalic vein for autologous arteriovenous fistula is the preferred method of establishing dialysis access.
Hemodialysis patients should go to regular hospitals for fistulas, under the guidance of professional physicians.
