This word belongs to doctors and science. It means “about the kidneys” — the two parts in your lower back that clean the blood and make urine. You will see it in phrases like renal failure (when the kidneys stop working well) or renal disease. Everyday English usually just says kidney: kidney problems, kidney transplant. Renal sounds more formal and medical; you would not tell a friend “my renal hurts.” Though actually, hospital notes and health news very often choose renal for the describing word, while kidney is the word people use for the body part itself.
