I know this was covered in the Atkins world, I read about several people doing Atkins (low carb, high fat) with on kidney who ha no problems at all. Remember this is NOT a high protein lifestyle, about 25% is the maximum. It is high fat, and that should not bother your kidney function at all.
High protein can cause problems, but only if you are already suffering fairly advance kidney disease.
If you are worried, speak to your specialist & ask his advice on the maximum amount of protein safe for you to consume.
