Which condition is characterized by having blood in the urine?

The condition characterized by having blood in the urine is hematuria. When a person experiences hematuria, it indicates that there are visible traces of blood in their urine, which can be caused by various underlying issues, such as infections, kidney stones, or other medical conditions affecting the urinary tract.

Involuntary incontinence refers to the inability to control urination, resulting in accidental leakage, but does not specifically pertain to the presence of blood. Dysuria describes painful or difficult urination but does not indicate blood is present in the urine. Oliguria refers to a reduced output of urine, which can be a sign of kidney issues or dehydration, but again does not relate to the presence of blood. Understanding each of these terms helps clarify the specific nature of hematuria and its distinction from other urinary conditions.
