About 2-3 weeks ago I had a CT Urogram because I had gross hematuria and white blood cells in my urine. The CT showed a 16 mm kidney stone in my left kidney but no other abnormal results. I have noticed recently an increase in the bubbles in my urine. Could this be because of the large kidney stone that I have in my one kidney? . I am very concerned because with all the research I have done on the internet, I am seeing that the bubbles could indicate protein in the urine caused by a kidney problem. I am hoping that the bubbles are from the kidney stone irritating the kidney. Could this be? I am scared that my kidneys are not functioning as they should. I am a diet controlled diabetic and have been for 13-14 years, but my A1C averages has been excellent... around a 5.5.
