In microscopic hematuria, the urine appears normal to the naked eye, but examination under a microscope shows a high number of RBCs. In gross hematuria, the urine is red or the color of cola, which can be seen with the naked eye. Most of the causes are not serious, but, because hematuria may be the result of a tumor or other serious problem, a doctor should be consulted.
Several conditions can cause hematuria.
For example, exercise may cause hematuria that goes away in 24 hours. Many people have hematuria without having any other related problems. To determine the cause of hematuria, or to rule out certain causes, a series of tests may be ordered. Treatment for hematuria also depends on the condition's underlying cause. Consult your doctor for more information.
