Blood in urine indicates that you are having bleeding form either the kidneys, ureter, urinary bladder or the urethra. It could be infection, ulcerations, polyps, stones, and sometimes due to any kind of growth. It is best you consult a Nephrologist. Doctor would get your urine testing done, including bacterial culture, renal function tests, Abdominal X Ray, for Kidneys, ureter and Bladder, and if required and MRI scan and cysto- uretero scopy. The diagnosis would be made by these tests and Doctor can then advise you on the management.
