We have 2 kidneys, but only need one. Unfortunately some diseases attack both. Lupus is one of those. About 50% of people with lupus get inflammation of the kidneys. But it can range from mild to severe. I guess I’m one of those. My most recent urine test showed I am spilling some protein into my urine so now I’m doing a 24 hour urine to see how much protein I am actually losing (any single urine test is only a spot in time so you need a longer collection to see what is really happening). Depending on the results, I may need a kidney biopsy. I do know that I have had protein in my urine occasionally over the last year (and I think I remember having some protein in my urine back in residency)- so I’m hoping that is good news- that my inflammation is mild, and hasn’t progressed too much over the past several years. Most serious kidney problems occur in the first 10 years of having lupus.
So keep your fingers crossed that my urine test comes back OK. I’m honestly a little afraid to cross my own.
