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

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.
