Pus Cells and Epithelial Cells



What are pus cells and eipthelial cells? Why are pus cells and epithelial cells seen in urine occasionally?


"Pus" cells generally refer to white blood cells and can be an indicator of infection. Epithelial cells make up the inner lining of the urinary tract from the kidneys down through the bladder. They are occasionsally shed as new cells form. Persistant white cells in the urine should be evaluated to rule out infection.
