The story of the word

κύστις was the bladder itself, the pouch that holds liquid. Anatomists kept it for any closed sac, and pathologists narrowed it to the sacs that should not be there. Cystitis still points at the original organ, which is why one root covers both a urinary infection and a lump on the back of a wrist.
