My 89 year old father’s kidneys are functioning at 20%. He also has multiple other health issues including heart disease and COPD. With only a 20% kidney function, how soon is he likely to need dialysis? Any idea of what sort of life expectancy we are looking at?

I am unable to provide a prognosis without performing a complete history and physical examination.  It is best to ask the nephrologist who is providing care for your father.  In some cases, his heart disease or his lung disease may be more important to his life expectancy than his kidney disease.  I suggest that you consult with his primary care physician (PCP) and also seek consultation with his nephrologist for the most accurate prognosis.
