Quizplus · Accepted Answer

Epithelial cell casts are most closely associated with tubular damage. They are formed when renal tubular epithelial cells detach from the tubular wall and are carried into the urine, indicating damage to the tubular wall. WBC casts are associated with inflammation or infection, RBC casts with glomerular damage, and fatty casts with lipiduria.
