Enlarged Prostate

One of the possible reasons that older men have a higher rate of Hematuria is that prostate enlargement is also common in older men. While usually harmless, an enlarged prostate can leak blood into the urinary tract. This is very common and is actually the number one cause of visible blood in the urine for men over 50.

Kidney Disease

As the filter for our blood, the kidney has blood and urine in extremely close proximity to one another. In kidney disease, damage to the filters of the kidney can allow blood to directly entire the urine. There are numerous causes of kidney disease and many of them result in damage to the filtering ability of the kidney.


One last cause of Hematuria to mention here, is due to cancer. Cancer anywhere along the urinary tract from the kidneys to the urethra can result in blood in our urine. In men, this list also includes prostate cancer. In most cases, when people observe blood in their urine, cancer is the first thing that comes to mind. As we age, the risks of Hematuria being due to cancer do increase making the need for a physician’s visit an important activity.

Unknown Causes

Often the cause for the presence of blood in our urine cannot be readily determined. In a study published in 2000 in the Journal of Urology, the researchers, studying almost 2000 patients, found no cause for Hematuria in 61% of the patients who showed the symptom. That same research found a UTI in 13% of patients, kidney stones in 2% and bladder cancer in 12% of patients. Consequently, as patients, we should not be surprised when our doctors are unable to explain the cause of blood in our urine.


Discovering blood in our urine can cause some of us excessive concern and can be dismissed by others. However, the best and safest response to such a personal discovery is a prompt visit with our physician. In many cases, the symptom has no long-term effect on our health. In other cases, it can point to infection that requires treatment but is not a significant concern. Sometimes however, it signals cancer and for this reason, caution and a physicians visit is most appropriate response to the discovery of blood in our urine.
