I had slight blood in urine for about 6 hrs which went away. I went to a very reputable urologist and had a c scan with contrast.... all good. Yesterday had a cystoscopy, all good also. As we were watching it on the TV he saw a spot, put a light on it and told me it was nothing. I know it was not the blue light as there was no one hr dye prior. Any comments? I am female and at the time of the blood had a significant klebsilla uti which is now clear....no pain. Any comments would be much appreciated. I know this urologist personally and his rep is excellent.. thanks!
