Does hematuria mean that the urine is red?

Tumors of the urinary system have a common feature, that is, they often have hematuria, but hematuria and "urine is red" are not exactly the same.

If you do not eat any special drugs or foods, but find that the color of the urine is red, basically can determine that hematuria has occurred, at this time we call it gross hematuria, the color of the urine can be red, can also be coffee or soy sauce color.

However, in addition to "gross hematuria", hematuria can also be microscopic hematuria, that is, under the microscope, more red blood cells can be observed in the urine.

Because the human body produces about 1000-2000ml of urine every day, if the amount of bleeding is small, in fact, it is invisible to the naked eye, and it is necessary to go to the hospital to check the number of red blood cells in the urine to determine whether hematuria has occurred.

When the bleeding situation is more serious and the amount of bleeding is more, the color of the urine can change, which can be seen by the naked eye.

Therefore, when we can see hematuria with the naked eye, it means that the situation is more serious, especially if there is painless gross hematuria, we must be more vigilant and must go to the hospital to rule out the possibility of urinary system tumors.

Clinically, we often see such patients, today pee once hematuria, the next day there is no, because the urination process is not painful, think well, there is no attention.

By the time hematuria is found again for many months, the tumor may already be very large. So don't wait until severe hematuria occurs repeatedly before going to the doctor, as long as you find hematuria, you should see a doctor in time.
