nephrolithiasis

From international scientific vocabulary, using New Latin combining forms, from nephro- +‎ lithiasis = nephrolith +‎ -iasis = nephro- +‎ lith +‎ -iasis.

nephrolithiasis (uncountable)

1. (biology, medicine) Formation of, and thus also presence of, calculi in the kidneys (kidney stones).

• urolithiasis (sensu stricto, coordinate, but in practice any stone passed in the urine may be called a kidney stone, as the locus of its formation may not yet be known; and thus many mentions of urolithiasis and nephrolithiasis are loosely synonymous, which is to say, not precisely differentiated)
