Blood in the Urine
Blood in the urine, medically known as hematuria, is a condition we frequently evaluate because it can be an early sign of problems in the kidneys, bladder, or urinary tract. Sometimes the blood is clearly visible as pink, red, or brown discoloration, while in many cases it is detected only on routine urine tests. Even when the patient feels completely normal, hematuria should never be ignored, as it may indicate infections, stones, inflammation, or, in rare cases, more serious conditions.
Early assessment helps us determine the exact cause and prevent future complications. With proper testing—including urine analysis, ultrasound, and in some cases, blood tests or CT scans—we can identify the underlying issue and plan the most appropriate treatment. Prompt evaluation ensures that kidney function remains protected and long-term damage is avoided.
Common Causes of Blood in the Urine
- Kidney stones – Sharp crystals can irritate the urinary tract and cause bleeding.
- Urinary tract infections – Inflammation can lead to microscopic or visible blood.
- Bladder or kidney infections – Often associated with burning urination or fever.
- Kidney inflammation (glomerulonephritis) – Affects the filtering units of the kidney.
- Prostate enlargement – Can cause bleeding in men, especially with straining.
- Certain medications – Blood thinners or painkillers may contribute.
- Exercise-induced hematuria – Intense physical activity may cause temporary blood in urine.
- Rare but important causes – Tumors or structural abnormalities of kidneys or bladder.
Symptoms Patients Should Watch For
Besides visible or microscopic blood, some patients may notice:
- Pain in the back, side, or lower abdomen
- Burning sensation while urinating
- Frequent urge to urinate
- Fever or chills if infection is present
- Difficulty or discomfort during urination
- Foamy urine or swelling in some kidney-related conditions
