What condition is indicated by hematuria?

Hematuria refers specifically to the presence of blood in the urine. This condition can indicate various underlying issues, such as urinary tract infections, kidney stones, or more serious conditions like kidney disease or cancer. The term itself is derived from the Greek words "haima," meaning blood, and "ouron," meaning urine. Understanding hematuria is essential for EMTs and healthcare providers, as it guides them in assessing a patient's condition and determining appropriate interventions. The other options relate to blood in different parts of the body, such as the lungs or eyes, but do not pertain to urine.
