Urine test showed occult blood

Both urine and feces are excreted through the human intestinal system and urinary system, so both urine and feces can well reflect some disease conditions inside the human body. When you find that there are some problems with your urine, you can actually do a routine urine test. If a person has a routine urine test and the result is occult blood in the urine, what disease is it?

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.
