Generally, blood which comes from kidneys makes the urine look like cola (brownish) and is well mixed with urine, there are no symptoms of irritation like frequency. There may be clots also if the bleeding is occurring from the kidneys. Common causes of such an occurrence are Nephritis, calculi (stones) or malignancies and these can be differentiated by certain tests. Patients who have nephritis are further treated by Nephrologists while others by Pediatric Urologists.
