See below: How do you know you don't have a stone? Did you have a ct scan? Was a urine culture done to rule out infection? Blood in the urine needs a standardized work-up to determine the cause - including a ct scan with and without IV contrast and a cystoscopy (where the urologist looks inside your bladder with a telescope).
