ways to keep your access going after a transplant?

[sullidog]

I've read about what could happen to your access after transplant, but my question is is there somethings that one could do to keep their access thrilling away for many years after they are transplanted, so if that kidney fails the access would not need to be replaced because it's still buzzing away. I have a graft and running out of spots for accesses, this is why I asked this question.
