Being on dialysis and needing a transplant is a huge distress to anyone.
Being in UK or Canada doesn't help much at all.

In the UK the waiting time for a deceased donor kidney transplant is minimum 2 to 5 years simply because the demand in the UK is far higher than the available supply of donors.
Waiting times depend on many factors including age.

Needing just one kidney isn't too bad as family members can donate.

As far as I know living on dialysis isn't a long term otion with average life expectancy of just 5-10 years. If you're lucky just enough time to find a transplant. With some good luck some folks might make it on dialysis for 20 or even 30 years. Max
