Hi Kim; I can feel the fear and stress in your words. I have never had kidney involvement with my Lupus and, as most of your questions requested information from member who have, I will wait to see how many members(with personal experience) respond to you.
Should you fail to get responses or if you want more research, please let me know and I will do a research for you.
In the meantime, please try not to over stress yourself until you get some definitive answers. You know how many problems stress can cause for this disease.
I will check again tomorrow to see where we are and/or what you need.
Peace and Blessings
