Occult blood**.
Generally speaking, it can be attributed to the following three causes, one is inflammation, one is stones, and the other is tumor.
In terms of inflammation, such as glomerulonephritis, pyelonephritis, cystitis, etc., in addition to hematuria, urine examination will also cause occult blood, whether it is kidney, ureteral or bladder stones, and other conditions such as menstrual period, constipation may also cause occult blood.
What is really worrying is the occult blood caused by tumors, such as benign or malignant tumors of kidneys, bladder and ureters, of course, older men because of prostate hypertrophy and because of excess urine, bladder inflammation, blood vessel congestion on the surface of the prostate, plus difficulty urinating, after straining to deurinate, hematuria or occult blood may occur, in fact, prostate hypertrophy is also a kind of tumor, it is a tumor of the prostate gland, hypertrophy due to hyperplasia, so the tumor of the urinary tract can not be taken lightly.
Basically, occult blood has different considerations for different ages and genders, for example, if a young woman finds occult blood during a urine test, in addition to clinical symptoms, you should ask whether it is a proper menstrual period, cystitis is a common cause; However, if a man is 30-40 years old, if there are no obvious symptoms of inflammation, sometimes an abdominal x-ray should be taken to see if there is a possibility of stones, and in older men, hematuria or occult blood, prostatic hypertrophy should be listed as the main considerations, and further intravenous pyelogram or ultrasound examination should be performed to see if there is a tumor in the urinary system.
In addition, urine cytology to see if there are malignant cells in the urinary epithelium, which is shed in the urine, is also one of the ways to detect whether there is a malignant tumor, if X-ray, ultrasound and urine cytology are normal, there is still occult blood, it is best to undergo cystourethroscopy, because X-ray, ultrasound are restrictive, not all tumors can be seen, at this time, only with the help of the naked eye to directly observe the smaller lesion (cystourethroscopy), If there are no abnormal findings in these tests, we call this occult blood or hematuria "benign unexplained hematuria", which may be related to the body's immune system, and only need to be followed up regularly in the future.
Occult blood bothers some people, and a very small percentage is caused by tumors, which should not be taken lightly, and if the series of tests are correct, you can also calmly face the worry without excessive worry. In addition, occult blood is a hematuria reaction that cannot be seen by the naked eye, and it is not easy for ordinary people to self-detect, so it is recommended that people develop the habit of regular health check-ups, and urine tests once a year can ensure the health and happiness of the urinary tract.

If the number of red blood cells under high magnification is more than 3, or even a large amount, it is necessary to check the hematuriary system, including phase microscopy of red blood cell malformation rate, urinary color ultrasound, IVP, magnetic resonance water imaging, complement C3, anti-O, and related examinations.
