My father in law is 76, recently had an MRI and they have detected dark shadows at the bottom of both his kidneys.  His kidney function is only 50%, now they are suggesting some laproscopic procedure to remove parts of both kidneys.  I am not sure what the procedure entails, I am more worried that he will end up having renal failure and have to go only dyalisis.  He is currently not in any pain - shouldnt he just live with it instead of undergoing surgery?
Dear friend, It needs confirmed diagnosis before any surgical procedure. You not provide it. You can give detail about MRI report. If it is malignancy, mostly Renal cell carcinoma then surgical treatment is the only option. As you told, they planned for bilateral some part removing, then it may be partial neurectomy. It doesn't end up with renal failure. If malignancy is diagnosis then u can go for surgery without much thinking about dialysis.
