Recently, when I was in an expert clinic, I met some hematuria patients who were very nervous or suspected that they had kidney disease or tumor. In fact, whether they are really hematuria patients has not been screened. Hematuria is red blood cells excreted in urine, and the signal of urinary system is abnormally increased in some diseases. If hematuria is found, we must first determine whether it is true hematuria, that is, to exclude false hematuria and red urine for some reasons. The former can cause menstrual disorder, hemorrhoid bleeding or bleeding near the urethral orifice, and mixed blood enters the urine, while the latter can cause hemoglobinuria or myoglobinuria due to contact with certain pigments or oral rifampicin drugs and some toxic drugs (phenol, carbon monoxide, chloroform, snake venom) (sulfonamides, quinine), crush injury, burns, malaria, improper blood transfusion, etc. Transient hematuria can cause allergies to pollen, chemicals or drugs. During menstruation and after strenuous exercise, viral infection can also cause transient hematuria, which has general clinical significance. Urology Department of Armed Police General Hospital
Only by excluding all these conditions, polyuria can lead to hematuria, and systematic examination should be carefully screened. In the diagnosis of hematuria, it is further clarified that drug-induced hematuria and hematuria refer to hematuria caused by kidney diseases, including * * * nephropathy (primary kidney diseases: acute glomerulonephritis, acute glomerulonephritis, occult glomerulonephritis, chronic glomerulonephritis, nephrotic syndrome or surgery, IgA nephropathy secondary nephropathy: systemic lupus erythematosus nephritis, allergic purpura nephritis, diabetic nephropathy, etc. The morphological characteristics of red blood cells in urine are often different in size and shape, while the morphology of red blood cells in urine is often the same in size and shape for various urinary system diseases caused by bleeding, as well as common diseases, including stones, tuberculosis, urinary tract infection, various traumas, congenital malformations, tumors, surgical hematuria, etc. It is important to determine the cause of hematuria, and it is also important to determine the location where hematuria occurs.
With the update of examination methods and the improvement of technical level, the causes of many hematuria have been completely identified. Can a simple three-cup urine test help us to think as a whole? The source of hematuria. Use three cups. As time goes by, the first cup of urine takes the urine in the front section, the second cup takes the urine in the back section, and the third cup takes the urine in the back section. For example, the first cup is hematuria, indicating that the blood comes from the urethral orifice, and the last cup of hematuria is mostly in the bladder or urethra. The first cup, the second cup and the third cup are all hematuria, suggesting that the lesion is in the urinary tract above the kidney or bladder. Be alert to urinary system tumors in the elderly, such as painless hematuria. If you have hematuria, you can disagree and there is no need to panic. You should go to a hospital expert for treatment.
