# Cystic kidney diseases: comparison table

- Topic

Cysts in the kidney range from harmless simple cysts to inherited diseases that end in kidney failure; one table sorts them.

Updated Nov 12, 2026

## Key points

- Most inherited cystic diseases are ciliopathies: defects in the primary cilium of tubular cells.
- ADPKD: adults, huge kidneys, extrarenal cysts and aneurysms.
- ARPKD: neonates, enlarged spongy kidneys with radial cysts, congenital hepatic fibrosis.
- Nephronophthisis: small kidneys with medullary cysts, childhood kidney failure.
- Multicystic dysplasia: unilateral in most, disorganized kidney with cartilage, the commonest abdominal mass in newborns along with hydronephrosis.

## What it is

Renal cysts are a frequent finding and a frequent exam topic. Inherited ciliopathies (ADPKD, ARPKD, nephronophthisis) and developmental disorders (multicystic dysplasia) must be separated from acquired cysts of dialysis and the simple cysts of aging. The age at presentation, kidney size, which part of the nephron forms the cysts and the organs outside the kidney give the answer.

## Renal cystic diseases

| Disease | Inheritance | Presentation | Kidneys | Outcome |
| --- | --- | --- | --- | --- |
| [ADPKD](https://durgical.com/en/conditions/autosomal-dominant-polycystic-kidney-disease/) | Autosomal dominant (PKD1, PKD2) | Adults; pain, hematuria, hypertension | Very large, bilateral cysts | Kidney failure in many by late middle age |
| [ARPKD](https://durgical.com/en/conditions/autosomal-recessive-polycystic-kidney-disease/) | Autosomal recessive (PKHD1) | Perinatal or childhood | Large, spongy, radial cysts | Neonatal death or childhood failure; liver fibrosis |
| [Medullary sponge kidney](https://durgical.com/en/conditions/medullary-sponge-kidney-and-medullary-cystic-disease/) | Mostly sporadic | Adults; stones, infection, hematuria | Normal size, cysts in medullary collecting ducts | Usually good |
| Nephronophthisis | Autosomal recessive (NPHP genes) | Childhood polyuria, growth failure | Small, cysts at corticomedullary junction | Kidney failure in youth |
| Multicystic dysplasia | Sporadic | Newborn flank mass | Usually one side, disorganized, cartilage | Other kidney carries the load |
| Acquired cystic disease | Acquired (dialysis) | Long-term dialysis | Small kidneys with many cysts | Higher risk of renal cell carcinoma |
| Simple cysts | Acquired, aging | Incidental | Single or few cortical cysts | Harmless |

## Clinical notes

- Ultrasound criteria by age and family history diagnose ADPKD in families at risk.
- A complex cyst (septa, solid parts) needs evaluation for renal cell carcinoma.

## Memory aid

Big and late: dominant; big and early: recessive; small and medullary: nephronophthisis; one-sided and bizarre: dysplasia.

## Test yourself
