I had kub ultrasound and the finding is "renal parenchymal disease, bilateral". how long will i live?

Renal Disease: You need to be evaluated by a nephrologist (n). A n will order a 24 hour urine for creatinine clearance and protein and take blood when you return the collection. This will tell the amount of kidney function you have left and will tell the n if you have a lot of protein in your urine. Once a diagnosis of the cause of you renal disease is made, a prognosis can be made as treatment starts.

Don't worry yet: Please see a nephrologist. Usually this can happen with hypertension or diabetes but there are a host of causes. It depends on how much disease there is and if it would be reversible. You probably need some lab tests, or even kidney biopsy to determine treatment, diet changes, ect. Even if you need dialysis or transplant there are people living for a long time on those. So don't worry yet.
