Blood in urine is hematuria, also known as hematuria.Under normal circumstances, there is no red blood cells in urine.Normal urine contains a small amount of red blood cells without centrifugal urine in each high -power field of each high mirror. If this number exceeds this, it is hematuria.If the eyes can see that the urine is "laundering water" or blood color, and even blood wire or blood clots in the urine, called the naked eye hematuria.It is worth pointing out that hematuria can not be discovered by the eyes.
Cause of hematuria
More than 95%of hematuria is caused by urinary system infection. Among them, diseases such as glomerular diseases, renal cysts, prostate hyperplasia, and urinary tract infections are most common.Hemorrhagic cystitis, urinary stones, renal tuberculosis, renal tumors, kidney and urethral damage, etc. may also cause hematuria.Hematheism is one of the main symptoms of these diseases.
1. Urban stones: including kidney, ureter, bladder or urethral stones.
2. Infection of urogenital system: such as pyelonephritis, renal tuberculosis, bladder urethritis, etc.
3. Nephritis: Including acute and chronic nephritis, dynamic nephritis, benign acute hemorrhagic nephritis, etc.
4. Urban tumors: kidney tumors, ureter tumors, bladder tumors, prostate tumors, etc.
5. Other urinary diseases: such as kidney sagging, swimming kidney, congenital polycystic kidney, etc.
6. Urinary damage: various chemicals or drugs to damage to the kidneys, blooduria caused by sulfa drugs, etc.
The difficulty in the treatment of urinary infection diseases is related to many factors. It mainly includes: the treatment of the early stages of the onset is irregular, blindly taking medicine and destroying the internal environment, causing bacterial resistance; repeated condition, long -term inflammatory damage, causing immunity to decrease, bringing treatment to treatment.difficulty.In recent years, some special bacteria (such as non -gonococcal, chlamydia, and mycoplasma) have more complicated the treatment of this disease.
Two more urine routine examinations
Urine routine examination is one of the most widely used clinical tests, which is related to a variety of diseases, especially kidney disease, but the urine label is far less stable than the blood specimen. In terms of testing, it is also vulnerable to some factors. ThereforeTime to do two more routine urine examinations to confirm whether hematuria is true.
Reminder: Many times the causes of hematuria are complicated and diverse, and the causes need to be checked repeatedly to find out the cause.Therefore, when hematuria occurs, we need to do a standardized examination again.
