What causes hematuria after sex?

If hematuria occurs after sexual intercourse, we need to consider whether it is caused by urinary system diseases. Also, if you suffer from some systemic diseases, such as sepsis, leukemia, and heart failure, these symptoms may also be caused.

There are many causes of hematuria, which generally include the following:

1. Urinary system diseases

Such as various nephritis (acute glomerulonephritis, viral nephritis, hereditary nephritis, purpuric nephritis), stones (kidney, bladder, urethra), heart and kidney tuberculosis, various congenital malformations, trauma, tumors, etc. ?

2. Systemic diseases such as hemorrhagic diseases, leukemia, heart failure, sepsis, vitamin C and K deficiency, hypercalciuria, neonatal bleeding, etc. ?

3. Physical and chemical factors such as food allergies, radiation exposure, drugs, poisons, and after exercise. In order to clarify the cause of the disease, it is very important to determine the location of hematuria. The three-cup urine test can understand the source of hematuria, and the method is very simple. ?

Take 3 cups. During one urination, the first cup is for the front urine, the second cup is for the middle urine, and the third cup is for the back urine. If the first cup of urine is hematuria, it means the blood comes from the urethra; if the third ... is coming from the urethra; if the first cup of urine is bloody, it means the blood is coming from the urethra; if the third cup of urine is bloody, it means the blood is coming from the urethra; if the first cup of urine is blood ?

To clarify which disease causes hematuria, it is still necessary to conduct various tests, X-ray and CT examinations, or even kidney biopsy based on symptoms and physical signs to confirm the diagnosis.
