  • gross hematuria – blood can be seen with the naked eye;
  • microscopic hematuria is found only in the urine.

Its divided into prerenal, renal and postrenal. Hematuria pyelonephritis refers to renal varieties. This means that there is an increase in permeability of the glomerular capillaries, glomerular basement membrane becomes permeable to red blood cells, affects the special structure of the kidney infectious process (involving venous plexus fornicating departments of the authority).

Also a big role in this process is intravascular coagulation. As a result, the red blood cells can penetrate into the urine. Also, scientists believe that the source of hematuria can serve as the papillae of the kidneys and the nephrons nekrotizirovannye, but it happens more often in chronic pyelonephritis.

Hematuria may be isolated (i.e. not combined with other symptoms) or combined (in parallel with leukocyturia and protein in the urine). Pyelonephritis is usually the second option prevails.

Also, there are minor, moderate and expressed degree of hematuria. But by the time of its occurrence there are beginner (blood only in the first portion of urine), total (blood in all parts) the terminal (blood in the end portion).

Thus, the patient passes urine all the rules of fence of this fluid. Further laboratory under a microscope it explores. Upon detection of red blood cells the conclusion of hematuria. It should be noted that this pathology can be detected not only by urinalysis, but also when taking a urine analysis according to Nechyporenko (this method is based on counting the number of red blood cells in the urine and to determine the microhematuria), when the sample Kakhovskogo-Addisa.
