Nodular glomerulosclerosis in diabetes, a common cause of chronic renal failure. H&E stain. (WC/KGH)

Renal failure, also kidney failure, is dysfunction of the kidneys.

It can be subdivided in a number of different ways.

Acutity

Acute kidney injury (abbreviated AKI) - previously acute renal failure (abbreviated ARF).
Chronic renal failure (CRF).

Acute kidney injury

Acute tubular necrosis.
Acute cardiac failure, e.g. myocardial infarction.
Cholesterol embolism.^[1]
Hepatorenal syndrome.

Chronic renal failure

Diabetic nephropathy (diabetes mellitus).
IgA nephropathy.
Autosomal dominant polycystic kidney disease.
Lupus nephritis (systemic lupus erythematosus).
Wegener's granulomatosis.
Chronic cardiac insufficiency (congestive heart failure).

Note:

The cause of end-stage renal disease (like end-stage liver disease) may be difficult to determine.

Anatomical cause

Renal failure 101:

Pre-renal.
Renal.
Post-renal.

Pre-renal

Hypotension due to blood loss (e.g. blunt force trauma, sharp force trauma, gunshot wound).
Reduced cardiac output, e.g. myocardial infarction.
Renal artery stenosis.

Renal

Post-renal

Nodular hyperplasia of the prostate.
Obstruction due to abdominal malignancy.
Posterior urethral valves.
