Does occult blood in urine mean nephritis? Does occult blood in urine mean nephritis?

In medicine, occult blood in urine mainly refers to the presence of a certain amount of hemoglobin in the patient's urine. Depending on the different hemoglobin content, the severity of occult blood in urine is also different. When patients suffer from nephritis, the chance of occult blood in urine will greatly increase. Nephritis mainly refers to inflammation caused by a virus infecting a person's kidneys, but if there is occult blood in the urine, does it mean it is definitely nephritis?

There are many reasons for occult blood in urine, common reasons include nephritis, arteriosclerosis, vascular malformations, stones, infection, renal ptosis, etc.

A weak positive protein result may be due to nephritis. It is recommended that you go to the hospital to check the location of hematuria.

Urine occult blood is detected through a routine urine test, which includes a red blood cell test. If the number of red blood cells increases (normal is negative), a small number can be called urine occult blood in terms of quantity, and urine occult blood itself can also be used as an indicator, whether it is negative or positive. If it is positive, how many pluses are there. Generally, occult blood in urine should be considered as it is caused by kidney problems or urinary tract infection.

Causes

The presence of red blood cells in urine cannot be observed with the naked eye or under a microscope, but there is a reaction when tested with a test strip. Why is this so? Because when red blood cells are destroyed, the hemoglobin contained in them will be released, so the urine test stick can detect the hemoglobin reaction. But why do red blood cells burst before leaving the body? This is because the lifespan of the red blood cells has come to an end and they dissolve on their own like foam. It may also be because after drinking a lot of water, the urine becomes thinner and the tension decreases, causing the red blood cells to burst. In any case, the presence of occult blood, like hematuria, is a warning sign and should not be taken lightly.

Generally speaking, occult blood in urine is attributed to the following three reasons: inflammation, stones, and tumors. Regarding inflammation, such as glomerulonephritis, pyelonephritis, cystitis, etc., in addition to hematuria, occult blood may also occur in urine tests. The stones themselves, whether they are kidney, ureter or bladder stones, may cause occult blood. Other situations such as constipation during menstruation may also cause occult blood.

In addition, tumors can also cause occult blood, such as benign or malignant tumors of the kidney, bladder, and ureter. Of course, older men have prostate hypertrophy and excessive residual urine, which makes the bladder prone to inflammation. The blood vessels on the surface of the prostate are congested, and they have difficulty urinating. After straining to urinate, they may have hematuria or occult blood. In fact, prostate hypertrophy is also a type of tumor. It is a tumor of the prostate, which becomes enlarged due to proliferation. Therefore, tumors of the urinary tract should not be taken lightly. At this time, intravenous pyelography should be performed. If there is no problem with the angiography, transitional cell tumor can be ruled out. Urinalysis should also be checked regularly. If there is still occult blood, you should go to the nephrology department for treatment and perform a renal puncture biopsy if necessary.

The most worrying thing is hematuria caused by nephritis. Many patients, including many children, suffer from repeated attacks of the disease due to kidney disease or incomplete treatment of the disease. They have hematuria and cannot find the cause. At this time, proteinuria and edema may also occur. At this time, they should not simply receive symptomatic treatment, but go to a specialist hospital for reexamination and systematic treatment based on the kidney disease and previous medical history.
