Renal Failure (ERF)
means the kidneys are now functioning below 15%. This is
sometimes called established kidney failure or end stage kidney
failure or end stage renal disease (ESRD).
When the percentage of kidney function is 15% or less (more often about 8%) a lot of people will not be able to live much longer without Renal Replacement Therapy (RRT).
RRT means the treatments of renal transplantation and the different forms of dialysis.
If somebody is very frail (and usually elderly) when their kidneys fail, RRT might not help them. It might be better if these people did not have RRT because RRT would probably not keep them alive significantly longer but it would probably lower their quality of life for the remainder of their days. People who choose not to have RRT when they reach ERF still get treated and this option is called Conservative Management of Kidney Failure.
