The reasons why men urinate with blood can be understood from seven aspects

1. Urinary stones.

2. Urinary and reproductive system infection.

Such as pyelonephritis, renal tuberculosis, cystourethritis, prostatitis, etc.

3. Nephritis.

These include acute and chronic nephritis, focal nephritis, benign acute hemorrhagic nephritis, etc.

4. Urogenital system tumors.

There are kidney tumors, ureteral tumors, bladder tumors, prostate tumors, etc.

5. Other urinary system diseases.

Such as kidney ptosis, wandering kidney, congenital polycystic kidney, etc.

6. Urinary tract injury.

Damage to the kidneys caused by various chemicals or drugs, hematuria caused by sulfonamides, etc.

7. There are some other reasons that can cause temporary hematuria.

For example, hematuria after exercise. Some people have hematuria after morning jogging or sports, but they do not feel any obvious discomfort or other associated symptoms. This is hematuria after exercise, and the cause is kidney damage after intense exercise. There is no special treatment for exercise-induced hematuria. You can take some hemostatic drugs and then rest until the hematuria disappears. In the future, you should start with a small amount of exercise and gradually increase it to improve the body's and kidneys' tolerance to exercise.
