Etymology: Nephrotomy is a plain technical compound, built from two Greek elements. The first, "nephro-", comes from Ancient Greek "nephrós", meaning "kidney", a word that traces back to a very old Indo-European root. The second, "-tomy", comes from "témnō", meaning "to cut", so the whole word literally means "kidney cutting". The pattern is a familiar one in medicine. Surgical names built on "-tomy" follow the same logic as "appendectomy" or "tracheotomy", where the suffix names the act of incision and the prefix names the organ. Nephrotomy describes a surgical incision into the kidney itself, and the term is a deliberate modern coinage from classical parts rather than a word that existed in antiquity.
