@whenley1968 and @sunnyflower, This is Chronic Kidney Disease (CKD): How do I stop progression? discussion I mentioned that would be a good place to share your story and ask any questions you may have. You mentioned you had an egfr in september a year ago. In March your egfr was 46 and creatinine was 1.68. You changed everything about how you ate and Renal Stenosis was the verdict. Since then you have had an egfr taken a couple more times. The next one was 55 and one last week said it was 66. So you are wondering if your kidney and renal stenosis are reversing itself?

These are the articles I listed in my first post that you may find helpful.
