What condition is characterized by blood in the urine?

Hematuria is the medical term used to describe the presence of blood in the urine. This condition can be indicative of various underlying health issues, such as infections in the urinary tract, kidney stones, or other kidney-related conditions. The detection of blood in urine can also signal injuries to the urinary system, or other serious conditions that may require prompt medical investigation.

Oliguria refers to the production of a significantly reduced amount of urine, which is not connected to the presence of blood. Dysuria means painful or difficult urination and does not specifically relate to blood. Nocturia is characterized by the need to wake at night to urinate, which again does not involve blood in the urine. These terms represent different urinary symptoms or conditions that do not overlap with the definition of hematuria.
