2gingerw, I still have no idea when or why my left kidney just dried up! Nobody knew this had happened until my eGFR dropped and I was referred to a Neph who ordered and MRI that showed a dried-up little bean on my left!

@gingerw, another update. As you already know (but others may not know,) am now in Stage 3b CKD. Am keeping fingers crossed, complying with neph and primary suggestions to try to have kidney remain stable and to better manage diabetes plus following a renal vegetarian (almost but not quite vegan because I do eat eggs for the protein) diet modified to help with the diabetes and with gastroparesis. It's a balancing act and I'm much more tired these days than I used to be. I actually weigh my food portions in grams and usually am able to maintain CKD recommendations for phosphorus, potassium, sodium, and protein, etc., plus watch fiber content for GP and try not to exceed carb limits to continue to need less insulin. It's practically a full time job to plan menus within the parameters but it can be done. I say, don't be afraid to read labels, look up nutritional values of various foods on the USDA website and other reliable websites and actually calculate daily totals before consuming meals for that day. It's a lot of trouble but this past Monday I made another trip around the sun and at 78 I'm still here! Hugs to all.
