What happened to the blood in the urine

summary

If the number of red blood cells in the urine increases, the patient will have the phenomenon of hematuria. Many patients will be particularly worried about what serious disease they have when they see that their urine is different from that of normal people. In fact, there is no need to worry too much. Now let's talk about the blood in urine.

What happened to the blood in the urine

First: hematuria refers to the abnormal increase of excretion of red blood cells in urine, which is a signal of possible serious diseases in the urinary system. Hematuria is defined as the abnormal increase of red blood cells in urine when there are more than 3 red blood cells per high-power microscopic field in centrifuged precipitation urine, or the red blood cell count exceeds 100000 in non centrifuged urine more than 1 hour or 1 hour, or the urine sediment count exceeds 500000 in 12 hours.

Second: light only microscopic red blood cell increase, known as microscopic hematuria; heavy appearance of meat washing water or containing blood clots, known as gross hematuria. It is usually visible to the naked eye when there is 1ml blood in every liter of urine, and the urine is red or meat washing water sample. Hematuria refers to the abnormal increase of excretion of red blood cells in urine, which is a signal of serious diseases in urinary system. There were more than 3 red blood cells per high power microscopic field in centrifuged precipitation urine, or more than 1 hour in non centrifuged urine or more than 100000 red blood cells per hour in urine.

Third: more than 95% of hematuria is caused by the diseases of urinary system, among which glomerular diseases, renal cysts, calculi (kidney, ureter, bladder, urethral calculi), prostatic hyperplasia, urinary tract infections (tuberculosis, pyelonephritis, bladder urethritis, prostatitis) and tumors (kidney, ureter, bladder, prostate tumor) are the most common. Other diseases such as coagulation disorders (idiopathic or drug-induced thrombocytopenia, hemophilia, scurvy, etc.), systemic diseases (aplastic anemia, leukemia, systemic lupus erythematosus, dermatomyositis, leptospirosis, epidemic hemorrhagic fever, etc.) can also cause hematuria.

matters needing attention

In general, the number of red blood cells in human urine is increased, so the color will become red, mild patients should pay special attention to their living habits. General blood color if it is particularly deep, then we have to go to the hospital to see, because it is likely that the urinary system appeared serious infection.
