IPA: //ˌpaɪ.ə.ləˈnɛf.rɪ.tɪk//
KK: /pɪˌɛləˈnɛfɹɪtɪk/
A term used to describe a condition related to inflammation of the kidney due to infection.
The patient was diagnosed with a pyelonephritic condition after showing symptoms of kidney infection.
Pyelonephritic is formed from "pyelo-" (from Greek "pyelos", meaning basin or pelvis) and "nephros" (meaning kidney) and the suffix "-itic" (meaning pertaining to). The term refers to a condition pertaining to the pelvis of the kidney.
Think of 'pyelo-' as referring to the 'basin' of the kidney and 'nephritic' as relating to the kidney itself, so pyelonephritic describes something that pertains to the kidney basin.
