different between kidney vs hydronephrosis

English

Etymology

From Middle English kednei, kidenei, from earlier kidn?re, kiden?re (“kidney”), of obscure origin and formation. Probably a compound consisting of Middle English *kid, *quid (“belly, womb”), from Old English cwiþ, cwiþa (“belly, womb, stomach”) + Middle English n?re (“kidney”), from Old English *n?ora (“kidney”), from Proto-Germanic *neurô (“kidney”), from Proto-Indo-European *neg??r- (“kidney”). If so, then related to Scots nere, neir (“kidney”), Saterland Frisian Njuure (“kidney”), Dutch nier (“kidney”), German Niere (“kidney”), Danish nyre (“kidney”), Norwegian nyre (“kidney”), Swedish njure (“kidney”), Ancient Greek ?????? (nephrós).

Alternate etymology traces the first element to Old English c?od, codd (“sack, scrotum”), from Proto-Germanic *keud? (“sack”) as the terms for testicle and kidney were often interchangeable in Germanic (compare Old High German nioro (“kidney", also "testicle”), Old Swedish vig-niauri (“testicle”). More at codpiece.
