Blood in urine. First make sure that the blood is not from the vagina. If it's not, blood in urine is abnormal and calls for evaluation of both the kidneys and the urinary bladder. Things like stones, growths, inflammation and infection have to be checked for, and a urologist is best to carry out the investigation.
