Final answer:
The presence of pus in the urine is described as pyuria, an indication of infection or other inflammatory conditions in the urinary system.
Step-by-step explanation:
The term used to describe urine that contains pus is pyuria. Pus is an accumulation of dead pathogens, neutrophils, tissue fluid, and other cells that may have been killed by phagocytes at the site of an infection. Pyuria indicates the presence of pus or white blood cells in the urine, which often suggests a urinary tract infection or other types of infection. It is not to be confused with hematuria which is the presence of red blood cells in urine, proteinuria which is the presence of protein (particularly albumin) in urine, or glycosuria which is the presence of glucose in urine.
