Blood in the urine, known as hematuria, commonly results from the following causes:
1. Urinary tract infections: Such as cystitis and pyelonephritis, bacterial infections can cause inflammation of the urinary mucosa, leading to bleeding.
2. Urinary system stones: Kidney stones, ureteral stones, or bladder stones can rub against the urinary mucosa during movement, causing injury and bleeding.
3. Urinary system tumors: Such as bladder tumors and kidney tumors; during tumor growth, surrounding blood vessels may be damaged, resulting in hematuria.
4. Kidney diseases: Such as glomerulonephritis and renal vascular diseases; these conditions can cause abnormal kidney filtration function, leading to hematuria.
5. Infectious diseases: Such as sepsis and epidemic hemorrhagic fever; pathogen infection can cause systemic inflammatory responses that may affect the urinary system.
6. Blood disorders: Such as leukemia and aplastic anemia; abnormalities in the blood system can lead to excessive red blood cell destruction or insufficient production, which may be accompanied by hematuria.
If you have any concerns, it is recommended to seek medical attention promptly.
