About 2-3 weeks ago I had a CT Urogram and it showed that I have a 16mm kidney stone in my left kidney and the test was negative for any other problems.. The reason for the CT was because I had gross hematuria and also white blood cells in my urine. Since that time, I have noticed many bubbles in my urine. Is that caused by the kidney stone? I have done some research on line and I am really concerned now that the bubbles are from protein in my urine that would indicated another kidney issue. Can you please give me some answers? Thanks...
