Renal failure makes a dog really, really nauseated. Normally I'm not into "tempting" a dog to eat, but you'll need to build some good eating habits back into him. It's like he got hit by a car and now he's afraid of car rides - you'll have to overcome his memory of food making him feel so horrible.
Try changing where you feed him. Offer him food that is nothing like the old stuff - use canned or a mix of canned and kibble for a while. Switch up mixers - different flavors of canned, very lightly scrambled egg, canned wild caught fish, ground meats, steamed veggies.
Keep the quality of food that you offer very high, so that if he eases up on his consumption, you can dig in your heels and use tough love, without worrying that just because he didn't feel like eating six cups of Dog Chow, his nutrition is going to suffer. Use very concentrated rations such as some of the grain frees that are coming out every day it seems, now.
Realize that it is ok to switch feeds fairly regularly, and in fact it's healthiest to do so, most people think now. So you can jump the gun on him and change before he gets bored, and it will sort of take the power away from him.
Good luck!
