"Nephrolith" Natural Recordings by Native Speakers
Nephrolith is a medical term that refers to kidney stones or calculi.
A nephrocele is a type of hernia that occurs in the area of the kidney. It is a protrusion of an organ or tissue through a weakened spot in the tissue that surrounds it. In this case, it is the tissue surrounding the kidney that is weak, allowing a part of the kidney or other nearby organs to bulge out through the weakened area.
