What is the reason for occult blood in urine routine test 10

A routine urine test shows an occult blood result of +1. Many people do not understand what this is all about. In fact, there are many reasons that may lead to this result. For example, some common inflammatory infections, or the presence of stones, as well as pyelonephritis and cystitis may all result in an occult blood result of +1 during the examination. Of course, it may also be caused by other physiological factors. Sometimes constipation can also cause occult blood.

1. Generally speaking, it can be 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.

2. What is really worrying is the occult blood caused by tumors, 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 gland, which becomes enlarged due to proliferation. Therefore, tumors of the urinary tract should not be taken lightly.

3. Basically, occult blood has different considerations at different ages and genders. For example, when occult blood is found in young women during urine tests, in addition to clinical symptoms, they should ask whether it is the normal menstrual period. Cystitis is a common cause. However, if it is a 30-40 year old male, 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. In addition to hematuria or occult blood in elderly men, prostatic hypertrophy is listed as the main consideration, and further intravenous pyelography or ultrasound examination should be performed to see if there is a tumor in the urinary system.

4. In addition, urine cytology can be used to check whether there are malignant cells in the urinary epithelium shed in the urine. It is also one of the methods to detect malignant tumors. If the X-ray, ultrasound and urine cytology are normal and there is still occult blood, it is best to undergo a cystourethroscopy. Because X-rays and ultrasounds are limited, not all tumors can be visualized. At this time, you can only use the naked eye to directly observe smaller lesions (cystourethroscopy). If these tests show no abnormal findings, we call this occult blood or hematuria "benign unexplained hematuria", which may be related to the body's immune mechanism and only requires regular follow-up in the future.
