Hematuria, or blood in the urine, can result from various conditions affecting the urinary tract, kidneys, or bladder. Causes range from urinary tract infections, kidney stones, or trauma to more serious conditions like kidney disease or cancer. Hematuria may be visible to the naked eye or detected through urine tests. Symptoms can vary from pink, red, or cola-colored urine to pain, burning sensation during urination, or no symptoms at all. Diagnosis involves medical history, physical examination, and further tests such as urine analysis, imaging studies, or cystoscopy. Treatment depends on the underlying cause and may include antibiotics, medications, or procedures to manage or resolve the condition.
