    Although people's health concepts in modern society have been widely improved, and more and more people have paid attention to physical examinations, many friends do not know much about the technical vocabulary used in physical examinations and do not understand the results of physical examinations. For example, if a male's urine routine examination is abnormal, many men do not know the cause. In fact, many men are in a relatively confused state after discovering some test results. They don't know why their urine is red. Let's take a look at the detailed introduction below.

    Men's urine may be reddish for the following reasons:

    1. Infectious diseases, pyelonephritis, acute cystitis, urethritis.

    2. Stones in the genitourinary system, such as stones in the urethra, acute obstruction, and endoscopic urinary tract stones after gravel treatment.

    3. Tumors of the urinary system, such as transitional cell carcinoma of the renal pelvis, urethra, and bladder.

    4. Trauma to the genitourinary system, injury to kidney function, renal contusion, and damage to the bladder and urethral opening.

    5. Patients with some medical diseases, such as coagulation function problems, long-term use of anticoagulants, and blood diseases.

    6. Part of it is caused by dietary factors. For example, a lot of dragon fruit and kiwi fruit with red heart pictures have been taken in a short period of time.

    Reasons for abnormal urine routine in male physical examination

    Abnormal white blood cell count: If the white blood cell count appears too high during routine urine examination, it may indicate urinary system infection, stones, tuberculosis, etc. If the patient has typical symptoms of frequent urination, urgency, inability to hold back urine, and painful urination, it can basically be diagnosed as a urinary tract infection. For recurrent chronic urinary tract infections, it is best to do a urine bacterial culture before taking medicine. Based on the established pathogenic bacteria and drug susceptibility test results, select appropriate antibiotic treatment.

    Abnormal blood cells: Normally there are no blood cells (or a few) in human urine. If blood cells are found in routine urine examination and exceed 3, it indicates inflammation of the urinary system, stones, tumors, nephritis, etc. It should be noted that when a woman detects blood cells in her urine, she needs to see if she is in her menstrual period to avoid positive results.

    Abnormal proteinuria: Proteinuria is a sign of nephritis and nephrotic syndrome. But don’t be afraid. Serious urinary tract infections and excessive exercise can also cause proteinuria. The amount in the test report is related to the amount of protein in the urine. To confirm the diagnosis, it is also necessary to check the 24-hour urinary protein quantification to confirm which kind of kidney disease it belongs to, and to distinguish the severity of the disease.
