Etymology: "Urolithiases" is simply the plural of "urolithiasis," the medical term for the formation of stones in the urinary tract. The singular is built from two Greek-derived elements: "uro-," from Greek "ouron," meaning urine, and "lithiasis," a term for the formation of stones, from Greek "lithos," meaning stone. The combined word is therefore a transparent compound, and its parts can be read straight off the medical vocabulary. An alternative analysis treats the first half as "urolith," a word for a urinary stone itself, with "-iasis" added to it. Either way, the pattern is the same: the Greek suffix "-iasis" signals a diseased or abnormal condition, so the word names the disorder rather than the stone alone. The plural form simply follows the Latin-style ending used by many medical terms ending in "-is," which change to "-es" in the plural.
