Hello,
If you have total kidney volume by MRI already measured. If so, please go to this page:
http://www.mayo.edu/research/documents/pkd-center-adpkd-classification/doc-20094754
Look to Box #3 and you can enter your respective values there in order to give the height-adjusted TKV with the corresponding risk level provided.
If you only have kidney dimensions, got to the same link above and use Box #1 which will calculate the estimated TKD. Once that is done, you can then proceed to Box 3 to make your volumes height adjusted.
