Two surgical techniques for creating kidney dialysis access

This trial is testing two different surgical techniques for creating an arteriovenous fistula, which is a connection between an artery and vein that allows blood to be filtered during dialysis. Researchers want to compare the end-to-side technique (the traditional approach) with a newer method called the Piggyback technique to see which one works better and has fewer complications. You would be randomly assigned to receive one of these two surgical approaches.

Many people with advanced kidney disease need hemodialysis to survive, but the surgical access points often fail or develop problems in the first few months. This trial exists because early studies suggest the newer Piggyback technique may be safer and more durable than the traditional method, but we need a larger, rigorous study to know for sure.
