Question: 1 / 400

What condition is identified by the presence of pus in urine?

Hematoma

Pyuria

The presence of pus in urine is specifically referred to as pyuria. This condition indicates an infection or inflammation within the urinary tract, which can be caused by bacteria, viruses, or other pathogens. Pyuria is characterized by a high white blood cell count in the urine, which reflects the body's immune response to the infection.

Hematoma refers to a localized collection of blood outside of blood vessels, which does not describe pus in urine. Hematuria, on the other hand, refers to blood in the urine, indicating bleeding rather than infection. Proteinuria signifies the presence of abnormal amounts of protein in the urine, commonly associated with kidney disease, but it does not involve pus. Therefore, the definition and clinical significance of pyuria make it the correct answer for identifying the condition characterized by pus in urine.
