Nephrosis

Nephrosis is any of various forms of kidney disease (nephropathy).

In an old and broad sense of the term, it is any nephropathy,[1] but in current usage the term is usually restricted to a narrower sense of nephropathy without inflammation or neoplasia,[2] in which sense it is distinguished from nephritis, which involves inflammation.

It is also defined as any purely degenerative disease of the renal tubules.

[1] Nephrosis is characterized by a set of signs called the nephrotic syndrome.

In other words, nephrosis and nephritis can be pathophysiologically contradistinguished, but that does not mean that they cannot occur simultaneously.
