Anemia and occult blood in urine are written on the physical examination report! What is the meaning of urine occult blood? Is it serious? Well, what's the matter?

Urinary occult blood is a name, that is, there is "potential bleeding" in urine, which is found by routine urine examination. There is a red blood cell in urine routine. If red blood cells increase (normally negative, indicated by "-"), count them according to their number.

In quantity, a few can become occult urine blood (positive, indicated by "+"). Positive urine occult blood can only show that urine contains red blood cells, but this is not the complete red blood cells that are really seen under the microscope, but the red blood cell components detected by the computer. Normal people's red blood cells are constantly destroyed and their components are excreted from urine, so some normal people's urine will also be positive for occult blood. In general, the number of red blood cells is 0- 1/, which belongs to the normal range. Hematuria can only be diagnosed when the red blood cells in urine are more than 3 /HP under microscope. Urine occult blood is an index for routine examination of human urine. One of the routine urine tests is to check the number of red blood cells in urine. If red blood cells increase (normally negative), a few of them can be called occult blood in terms of their number. As an index, urine occult blood can be divided into negative and positive. If it is positive, how much? Generally, occult blood in urine should be considered to be caused by kidney problems or urinary tract infections. Positive urine occult blood and hematuria indicate that there are red blood cells in urine, but they are not hematuria with naked eyes, but red blood cells are found by examination. Hematuria is divided into gross hematuria, total hematuria and urine occult blood positive; Three cups test is also used to analyze the source of hematuria in clinic. Three-cup test means that the patient leaves urine in three test tubes once, and hematuria is found in the first test tube, indicating that the bleeding site is in the urethra; If hematuria only appears in the last cup, it means that the bleeding site comes from the bladder; If all three cups are hematuria, it means that hematuria comes from the kidney. If there is a blood clot in the urine, it usually means

Bleeding of bladder or urethra.

The production of urine occult blood can't be observed with naked eyes or microscope, but if it is detected with test paper, it will react. Why? Because the hemoglobin contained in the red blood cells will be released when they are destroyed, the urine test stick can detect the hemoglobin reaction. But why do red blood cells break before they leave the body? This is because the life span of red blood cells has reached, and they dissolve themselves like foam. It may also be that drinking a lot of water makes the urine weak, the tension decreases, and the red blood cells rupture. No matter how occult blood exists,

Like hematuria, it is a warning signal and should not be taken lightly. The diagnosis of occult blood in urine basically has different considerations at different ages and genders. For example, young women's urine test found occult blood. In addition to clinical symptoms, we should also ask whether it is in the physiological period. Cystitis is a common cause. But if the male is 30-40 years old, if there are no obvious inflammatory symptoms, sometimes an abdominal X-ray should be taken to see if there is any possibility of stones. In addition to hematuria or occult blood and prostatic hypertrophy, elderly men should also receive further intravenous pyelography or ultrasound examination to check the urinary system.

Whether there is a tumor. In addition, urine cytology examination to see if there is malignant fine urine epithelial shedding.

The existence of cells is also one of the methods to detect whether there is malignant tumor, such as X-ray examination and ultrasonic examination.

And urine cytology is normal, and there is occult blood. It is best to accept cystourethroscopy because

Because X-rays and ultrasound are limited, not all tumors can be displayed. At this time, only the naked eye can help.

Then observe the smaller lesions (cystourethroscope). If there is nothing unusual in these tests, we will

This kind of occult blood or hematuria is called "benign unexplained hematuria", which may be related to the immune mechanism of the body. In the future,

Just follow it regularly. The causes of occult blood in urine generally come down to the following three reasons: inflammation, stones and tumors.

About inflammation, such as glomerulonephritis, pyelonephritis, cystitis, etc. In addition to hematuria,

There will also be occult blood in urine test, and stones themselves, whether kidney, ureter or bladder stones, may be made.

Becoming occult blood, physiological period, constipation and other conditions may also cause occult blood.

In addition, tumors can also cause occult blood, such as benign or malignant tumors of kidney, bladder and ureter.

Because of prostate hypertrophy, excessive urine, bladder inflammation, blood vessels congestion on the prostate surface, dysuria. After forced urination, hematuria or occult blood may occur. In fact, prostatic hypertrophy is also a kind of tumor. It is a tumor of prostate, which is enlarged by hyperplasia, so the tumor of urinary tract cannot be taken lightly. Intravenous pyelography should be done at this time. If there is no problem with angiography, transitional cell tumor can be ruled out. Check the urine routine regularly at ordinary times. If there is still occult blood, you should go to the Department of Nephrology and have a renal biopsy if necessary. I am most worried about hematuria caused by nephritis. Many patients, including many children, have kidney disease or

Incomplete treatment of the disease leads to recurrent attacks, and hematuria cannot be found, which may be accompanied at this time.

There is proteinuria and edema. At this time, we should not simply treat symptoms, but should focus on renal lesions and

Go to a specialized hospital for review of past medical history and systematic treatment. Treatment of occult blood in urine

After the test results came out, occult blood troubled some people. In addition to objective factors such as exercise hematuria and drug hematuria, relevant examinations should be carried out to make a clear diagnosis. When excluding urinary tract infection, stones, tumors and other factors, we should consider the possibility of kidney disease. At this time, you should go to the hospital as soon as possible. Many patients with occult blood in urine neglect treatment at the initial stage, thus delaying their illness. Renal diseases, such as acute and chronic nephritis, pyelonephritis, etc., will cause hematuria when various pathological injuries occur.

It leads to local microcirculation disturbance of damaged kidney, leading to ischemia and hypoxia of kidney tissue, thus releasing inflammatory mediators.

The process of renal fibrosis. At this time, glomerular local lesions will occur: mesangial cell proliferation, mesangial base.

With the increase of quality, the glomerular basement membrane changes, which leads to the damage of charge barrier and the increase of renal permeability.

Occult blood and proteinuria appear. With the leakage of hematuria and proteinuria, the renal damage is further aggravated, and the glomerulus gradually progresses to fibrosis.

Hardening stage. Clinically, systematic and targeted treatment should be taken to block the process of renal fibrosis in time and avoid its occurrence.

Avoid renal failure caused by the gradual decrease of functional nephron.
