Hematuria is a condition of red blood cells in the urine. This causes a change in the color of the urine to red, pink or cola. But, sometimes the color of urine remains same. Red blood cells in the urine can come from a variety of reasons indicative of different diseases.
Microscopic means that something is so tiny that it cannot be seen with a naked eye. You can see it only with a microscope. If you have microscopic hematuria, it means that you have red blood cells in your urine, but you can’t see the blood when you urinate with your eyes.
Blood in urine without pain can be a sign of a serious illness such as prostate cancer or bladder cancer. Kidney problems may also cause painless hematuria. Most common symptom of bladder cancer is blood in urine without pain.
Hematuria is a condition characterized by the presence of red blood cells in the urine. Generally, red blood cells are not present in urine because filters in the kidney prevent blood from entering the urine. In hematuria, the filters or other parts of the urinary tract may be responsible for leaking blood into the urine.
