What condition is characterized by blood in the urine?

Hematuria is the correct term for the presence of blood in the urine. This condition can be caused by a variety of issues, including urinary tract infections, kidney stones, or trauma to the urinary system. Hematuria can be visible to the naked eye, resulting in urine that appears pink or red, or it may be detected only through medical testing.

In contrast, hematochezia refers to the passage of fresh blood through the anus, typically indicating bleeding from the lower gastrointestinal tract. Hematemesis describes the act of vomiting blood, often associated with bleeding from the upper gastrointestinal tract. Melena pertains to the passage of black, tarry stools due to the presence of digested blood, typically originating from the upper digestive system. Understanding these distinctions is crucial for proper assessment and diagnosis in nursing practice.
