What are the Mayo Imaging Classification classes?

Class 1A ( 6%/year): very high risk, ESRD before 50.

How does Mayo class guide tolvaptan use?

Tolvaptan is indicated for rapidly progressive ADPKD. Mayo Class 1C-1E patients with eGFR >25 mL/min/1.73m2 are likely eligible. Class 1A-1B patients are unlikely to benefit.

Can eGFR-based prognosis replace imaging in ADPKD?

eGFR-based classification lags htTKV by years as GFR decline occurs late after extensive cyst growth. htTKV-based Mayo Classification identifies at-risk patients before GFR declines for timely tolvaptan initiation.

ADPKD Mayo Imaging Classification

Classify ADPKD progression risk using Mayo Imaging Classification 1A-1E based on age and htTKV. Class 1C-1E indicates rapidly progressive disease with likely ESRD before age 58.

How It Works

Classify ADPKD progression risk using Mayo Imaging Classification 1A-1E based on age and htTKV. Class 1C-1E indicates rapidly progressive disease with likely ESRD before age 58

Each component has a specific meaning:

Mayo Imaging Classification 1A-1E based on age — The mayo imaging classification 1a-1e based on age recorded for the scenario being assessed.
HtTKV — The httkv recorded for the scenario being assessed.

Note: Interpret the adpkd mayo classification result against the thresholds and context described above.

How to Use

Enter the Mayo Imaging Classification 1A-1E based on age, htTKV for the scenario you are assessing. Classify ADPKD progression risk using Mayo Imaging Classification 1A-1E based on age and htTKV. Class 1C-1E indicates rapidly progressive disease with likely ESRD before age 58. Use the adpkd mayo classification result to inform your calculation.
