Urine additives erythrocyte

 A very common is erythrocytes are found in urine that called hematuria. This means that red blood cells (RBCs) can be found in the urine. It is distinguished from a macro-microscopic haematuria. A microscopic hematuria is when so few red blood cells in urine, they can only be detected under a microscope. With a gross hematuria is a detectable with the naked eye, reddening of the urine.


Deformations of red blood cells in urine indicate the location of the damage
The evaluation of the urine contained red blood cells under the microscope is a very valuable type of examination for the doctor. Based on the amount of erythrocytes can be about the extent of bleeding is suspected. Depending on which of the erythrocyte shape, some of the localization of the bleeding can be predicted within the urinary tract. For example, the erythrocytes are deformed, so that speaks more for an injury within the kidney tissue, eg as part of glomerulonephritis (inflammation of the glomeruli), because it is the blood is pressed through the damaged structures. If the RBCs are deformed, but normally, that speaks more for a violation of the urinary tract (renal pelvis, ureter, bladder, urethra), for example through the ureter calculi.


Not always the kidneys are damaged.
Bleeding may also occur in people whose kidneys are fine. Thus, a hematuria also occurs with febrile illness or after heavy physical exertion. But typically go 75 per cent of all tumors on hematuria, infection, stones or blockages return within the urinary tract.


A haematuria diagnostic measures must be continued.
If the hematuria is an important diagnostic sign, it alone is not meaningful enough. Such a finding must always supplemented, on the one hand by imaging methods such as X-rays or ultrasound examinations, on the other hand, by further investigations of the urine sediment.
