Hi, I am a 29 yoa female that has had many urinary problems. I was diagnosed 3 years ago with a UPJ Obstruction in my left ureter, and have had 4 surgeries to correct it. The last surgery I had was in 2006. I also have had/have kidney stones in my left kidney, I passed a 13mm one in June 2006. In the past year I have not had any reoccuring problems with my obstuction and stones, although I still have 6mm stone in my left kidney. This past week, I did however urinate large amount of blood, my urine was cola colored. With my history I decided to go to the emergency room cause I was very concerned. I have not had any pains, or burning sensations, only large amounts of blood in my urine. The ER performed blood tests, urine tests and a CT scan all came back negative for any kind of infection or stones, with the exception on the 6mm ston in my kidney. I got no real answer why this may have happened. When I got home my urine seemed to clear up and go back to normal. I have done no exercising or activities that may have contributed to this, I also had no pain, so I don't believ I passed a stone. Should I be concerned? Or just let it go cause it cleared up on its own?
Thank you
