Prognosis for total kidney and liver failure dyalisis not an option, what type of life expectancy?

Depends: There are several foactors to consider. Discuss this with your physician.

Very poor: Unfortunately very poor however depends on what is meant my "total" failure. If complete kidney failure means not making any urine, then prognosis is typically days, up to 1-2 weeks w/o dialysis. If complete liver failure (your doctor would use prognostic tools such as meld and childs-pugh) and would consider lab values and signs/symptoms of liver failure and typically could be weeks to months.
