Egfr 72 (mdrd), age 45, controlled bp (ace), no protein in urine - how many years at this egfr can i expect to stay clear of end stage kidney failure?

Whoa: Estimated gfr's are subscientific. I see that you're hypertensive, but you can't possibly be in 'kidney failure', which you list, with an egfr of 72. They're based on creatinine which is a function of muscle, and (get this!) there's an adjustment of 25% for black people 'because african-americans are more muscular.' every gym dude is suddenly a kidney failure case, and most folks like you are ok.
