strange urine particles

Last Jan. I was diagnosed w/a mass on R. kidney. No insurance since. But, I've noticed along w/alot of back pain, both sides and flank pain, both sides, that there's these white foamy clusters of small bubble like particles. Also some clear, larger circles, that stand separately and are single like with a dark rim around the edges. So, that's 2 kinds of things I've seen here lately. Do you know if that's related to the kidney mass? I will have health ins. for Aug. only and am schedualed for some CT scans, w/and w/out contrast, but, NEED to know asap about this urine floating things>thank you for your help !! I also have little appetite, very tired and don't pee as often as ever before, some swelling of feet/hands. and very tired.
