Causes of Blood In Urine (Hematuria)

Blood in the urine can be caused by a number of different issues, ranging from strenuous exercise to kidney disease or bladder stones.

There are a number of reasons for blood being present in the urine (hematuria). Many of these are benign and should not be a cause for distress. However, everyone should be evaluated as it can be an indicator for a more serious issue.

Causes for blood in the urine include the following:

Urinary Tract Infections (UTI)

A urinary tract infection (UTI) is an infection of the urinary system, caused by bacteria that has entered the urinary tract.

Kidney Infection (Pyelonephritis)

A kidney infection is technically a urinary tract infection and can occur when bacteria enters the urinary tract via the urethra and makes its way to the kidneys where it multiplies.


Urinary bleeding may be a symptom of advanced prostate cancer, bladder cancer or kidney cancer.

Bladder Stones or Kidney Stones

Kidney stones and bladder stones are hard, solid crystals of various sizes formed from the salts in urine. Larger stones can be very painful when passed and can cause bleeding in the urinary tract.

Benign Prostatic Hyperplasia – Enlarged Prostate

As men get older the prostate can enlarge, which can restrict the flow of urine to the urethra. It can also cause blood to pass into the urine.

Kidney Disease or Kidney Trauma

Urinary bleeding is commonly a symptom of kidney disease, or can be the result of kidney trauma, such as a heavy blow to the organ from sports or an accident.

Strenuous Exercises

Very strenuous exercise may result in traces of blood being found in the urine, though it is unsure why.
