Urine with blood is hematuria, also known as hematuria. Normally, there are no red blood cells in the urine. In medicine, the patient's urine is centrifuged and precipitated and examined with a microscope. If there are more than 5 red blood cells in each high power field, it is called hematuria. What's the matter with blood in the urine? Let me tell you about it.

What's the matter with blood in the urine

First: hematuria is often caused by diseases of urinary organs. Human urine is produced in the kidney, through the renal pelvis, ureter, bladder, urethra discharge, all these organs have a disease, bleeding, can cause hematuria. Common causes of hematuria are nephritis, urinary tract infection, hemorrhagic cystitis, urinary calculi, renal tuberculosis, renal tumor, kidney and urethral injury and so on.

Second, when hematuria is found, we should first determine whether it is true hematuria, that is, exclude the false hematuria and red hematuria caused by some reasons. The former is caused by menstruation, hemorrhoid bleeding or bleeding near the urethral orifice mixed into the urine; the latter is caused by contact with some pigments or oral administration of rifampicin, some poisons (phenol, carbon monoxide, chloroform, snake venom), drugs (sulfanilamide, quinine), Hemoglobinuria or myoglobinuria caused by crush injury, burn, malaria and wrong blood transfusion.

Third: after the determination of true hematuria, the location diagnosis of hematuria should be carried out to distinguish whether hematuria comes from the renal parenchyma or from the urinary tract: ① if the tubular type is found in the urine sediment, especially the red blood cell tubular type, it means that the bleeding comes from the renal parenchyma; ② hematuria with more serious proteinuria is almost the sign of glomerular hematuria; ② hematuria with more serious proteinuria is the sign of glomerular hematuria; ③ If we can find the tube type containing immunoglobulin in urine, it is mostly renal parenchymal hemorrhage; ④ hematuria caused by glomerular diseases, most of its red blood cells are abnormal, with different shapes and sizes, but not glomerular hematuria, most of its red blood cells are normal in size, only a few are abnormal red blood cells.
