Kidney problems and ibs C and diets?

I have had kidney stones (since a couple of years) and ibs C for ten plus years and i can't figure out what to eat!?? I've been on low fodmap for 7 years which has helped but then i introduced AIP lately which helped me insanely much (some parts of it) but i still struggle with kidney pain and wanna go more kidney friendly in my diet,, but i get so overwhelmed with dietary schemes and restrictions upon restrictions and i don't know what to do... anyone have experienced similar combinations?
