What does hematuria refer to?

Hematuria specifically refers to the presence of blood in the urine. This condition can be a sign of various underlying health issues, such as infections, kidney stones, or more serious conditions like tumors or kidney injury. Identifying hematuria is crucial in clinical settings, as it often prompts further diagnostic evaluation to determine its cause and ensure appropriate treatment is provided.

The other options describe different urinary conditions that do not involve blood. For example, excessive urination at night is known as nocturia, scanty urinary output is referred to as oliguria, and excessive urination is generally referred to as polyuria. Each of these terms has a distinct definition and clinical significance that sets them apart from hematuria. Understanding these distinctions is essential for accurate medical documentation and patient care.
