Blood in the Urine (Hematuria) (cont.)
Blood in Urine Causes
- Infection: Blood in the urine can be a sign of urinary tract infection (UTI). An infection can be present in the lower urinary tract (bladder and urethra) or higher in the urinary tract (kidneys or ureters).
- Nephrolithiasis: Kidney or bladder stones may form inside the urinary tract and can cause bleeding into the urine.
- Kidney disease: Diseases of the kidney can be associated with blood in the urine.
- Prostate gland enlargement: Enlargement of the prostate can compress the urethra and partially block the flow of urine. Hematuria may be a symptom of an enlarged prostate caused by benign prostate hyperplasia (BPH or benign prostate enlargement) or prostate cancer.
- Cancers: Kidney and bladder cancers may be associated with blood in the urine.
- Injury: Trauma to the urinary tract can cause bleeding into the urine.
- Drugs: Medications including aspirin, heparin, and penicillin can cause hematuria.
- Strenuous exercise: Although the reasons are poorly understood, strenuous exercise has been associated with blood in the urine.
- Hematologic disorders: Disorders that affect the blood or the ability of the blood to clot can sometimes lead to hematuria. Sickle cell disease is one example of a blood disease that can cause bleeding in the urine.
