Hematuria is not necessarily hematuria, there are two clinical classifications: one is gross hematuria, which can be observed with the naked eye. The urine is red; the other is microscopic hematuria, that is, there are red blood cells in the urine, but the concentration is not enough to make the urine red, so it is not much different from ordinary light yellow urine to the naked eye. If gross hematuria is found, it is often more serious and requires immediate medical attention.
painless
Because the rupture of tumor cells is painless, the hematuria caused by it will not feel pain, which can be distinguished from the hematuria caused by stones and infections. Generally, hematuria caused by stones and infection will irritate the urinary tract, which is often accompanied by discomfort.
