I am a 76 year old woman. In February I was bleeding when I urinated. I went to specialist who did a cystoscope on me. She determined that the blood was coming from my left kidney which she checked and found nothing. She sad it was a hematuria. She also said there was no cancer. The bleeding stopped. I am going for my follow up visit on Monday. Today and yesterday I noticed tiny floating pieces of blood which worries me. Does anyone out there have this happen to them?
