Hematuria Blood Urine

Hematuria, often alarming yet usually benign, is a medical condition characterized by the presence of blood in the urine. Although generally not life-threatening, hematuria serves as a critical sign for various underlying health conditions, ranging from urinary tract infections to kidney diseases and cancer.

Types of Hematuria

Hematuria primarily divides into two categories: gross and microscopic.

Gross Hematuria

Gross hematuria refers to visible blood in the urine, giving it a pink, red, or cola-colored appearance. It’s often associated with a larger quantity of blood in the urine and may be indicative of severe underlying conditions.

Microscopic Hematuria

Microscopic hematuria, on the other hand, is detectable only under a microscope. Routine lab tests during regular check-ups or for other health concerns often reveal microscopic hematuria.

Causes of Hematuria

Hematuria can be traced back to a multitude of causes, including urinary tract or kidney infections, kidney disease, kidney stones, or certain cancers.

Urinary Tract and Kidney Infections

Infections in the urinary tract or kidneys often present hematuria as a symptom. These infections occur when bacteria enter the body through the urethra and proliferate in the bladder.

Kidney Diseases

Glomerulonephritis, a group of diseases that cause inflammation and damage to the kidney’s filtering units, is a common cause of hematuria.

Kidney Stones and Bladder Stones

Minerals in concentrated urine occasionally crystallize to form stones. These stones, though often painless, can cause hematuria.


Advanced stages of kidney or bladder cancer often cause visible blood in the urine.

Diagnosis of Hematuria

Diagnosis of hematuria involves an exhaustive process to determine the root cause. It may include a medical history review, physical examination, urine tests, imaging tests, and sometimes a cystoscopy.

Medical History and Physical Examination

The diagnosis process begins with a comprehensive review of medical history and a thorough physical examination to look for any signs or symptoms that may indicate the cause of hematuria.

Urine Tests

Urine tests, also known as urinalysis, are performed to find red blood cells in the urine. They also identify any other abnormal substances in the urine, such as proteins or glucose.

Imaging Tests

Imaging tests like ultrasounds or CT scans provide a detailed view of the urinary tract and help identify abnormalities that might cause bleeding.


In some cases, a cystoscopy may be required. This test allows your doctor to view the inside of your urethra and bladder with a thin, flexible instrument called a cystoscope.

Hematuria Treatment and Management

Treatment for hematuria is contingent upon the underlying condition causing the symptom. It may range from medications for infections to surgical procedures for cancers.


For urinary tract infections, antibiotics are typically prescribed. For kidney diseases, your doctor might recommend medications to prevent the kidneys’ filtering units from further damage.

Surgical Procedures

Surgical procedures might be necessary for cases of kidney stones, bladder stones, or cancers. The goal of these surgeries is to remove the source of bleeding.

Lifestyle Changes

Drinking plenty of fluids helps flush bacteria out of your system, reducing the risk of urinary tract infections. Maintaining a healthy diet and exercising regularly can prevent the formation of kidney stones.

In conclusion, hematuria is a symptom that should not be ignored. While it’s often not dangerous, it can be indicative of severe underlying conditions. If you notice any signs of hematuria, seek immediate medical attention. Always remember, prevention is better than cure. Stay healthy and keep regular appointments with your healthcare provider for early detection and better management of potential health issues.
