| Diagnosis in short | |
 End-stage kidney with thyroidization. H&E stain. | |
|

| LM | global sclerosis of the glomeruli, interstitial fibrosis, +/-thyroidization (colloid-like hyaline cast formation that impart an appearance that mimics the thyroid gland) |
| Gross | small kidneys, thinned renal cortex, +/-dilated renal calyces, +/-cysts |
| Site | kidney - see medical kidney diseases |

| Associated Dx | chronic pyelonephritis, acquired cystic disease-associated renal cell carcinoma, papillary renal cell carcinoma, acquired renal cystic disease |
| Clinical history | +/-diabetes mellitus (most common) |
End-stage kidney, abbreviated ESK, is a non-functional (chronically damaged) kidney.
End-stage renal disease (abbreviated ESRD) and end-stage kidney disease (abbreviated ESKD) redirect here.
General
- Many end-stage renal disease (ESRD) kidneys have a similar appearance.
- Notable exception: polycystic kidney diseases have distinctive appearance, e.g. ADPKD.
Gross
- Small kidneys.
- Thinned renal cortex.
- +/-Dilated renal calyces.
- +/-Cysts.
Note:
- Normal (adult) kidneys are ~11 cm from pole-to-pole.[1]
Microscopic
Features:
- Global sclerosis of the glomeruli.
- Interstitial fibrosis.
- +/-Thyroidization - colloid-like hyaline cast formation that impart an appearance that mimics the thyroid gland:[2]
- Typical of chronic pyelonephritis and obstructive nephropathy.
- +/-Interstitial nephritis.
- +/-Pyelonephritis.
Note:
- The end-stage kidney, much like the end-stage liver, often does not have apparent disease specific findings.
DDx:
- Diabetic nephropathy - most common cause of ESRD in North America, may have vague nodularity.
- Chronic pyelonephritis.
- Other causes of end-stage renal disease.
