Arteriovenous fistula (AVF) is the recommended vascular access for chronic hemodialysis, as it is associated with less mortality and better patency than arteriovenous graft (AVG) or central venous catheter (CVC). Unfortunately, AVF suffers from a high failure rate, due, in part, to poor venous diameter. The aim of this study is to investigate whether a perioperative handgrip training can improve the diameter of AVF in patients with chronic kidney disease (CKD) (stage IV-V).
