Blood in the urine; can be microscopic and not seen
Blood in the urine, also known as hematuria, refers to the presence of red blood cells in the urine
Blood in the urine, also known as hematuria, refers to the presence of red blood cells in the urine. It can be categorized into two types: microscopic hematuria, where blood is not visible to the naked eye and requires laboratory testing to detect, and gross hematuria, where blood can be observed visually.
Microscopic hematuria is usually detected during a routine urine analysis, where urine samples are examined under a microscope. It is important to note that even though the blood is not visible, it can still indicate an underlying health condition or problem. The causes of microscopic hematuria can be divided into two main categories: renal causes and non-renal causes.
Renal causes of microscopic hematuria are related to the kidneys or structures within the urinary tract. Some possible renal causes include kidney infections, kidney stones, glomerulonephritis (inflammation of the kidney’s filtering units), and polycystic kidney disease (a genetic disorder causing the growth of cysts in the kidneys).
Non-renal causes are associated with issues outside of the kidneys, such as the bladder, urethra, or prostate gland. These can include urinary tract infections, bladder infections or inflammation, bladder or kidney tumors, injury or trauma to the urinary tract, and certain medications or treatments that can irritate the urinary system.
It is important to investigate the underlying cause of microscopic hematuria to determine appropriate treatment. A medical professional, such as a urologist or nephrologist, may perform further tests, such as imaging studies (like ultrasound, CT scan, or MRI) and cystoscopy (inserting a thin tube with a camera into the urethra and bladder) to identify potential sources of bleeding.
Treatment for microscopic hematuria will depend on the underlying cause. In some cases, no specific treatment may be necessary, especially if the cause is benign and resolves on its own. However, if a more serious condition is identified, appropriate interventions may be needed to address the underlying issue.
It is essential to consult with a healthcare provider if blood is detected in the urine, even when it is not visible. They can thoroughly evaluate the situation, determine the cause, and recommend appropriate management or treatment to ensure the best possible outcome.
