So kidney transplant due to rare genetic condition? I don't know the details. Can someone give me the cliff notes?
They don't say what the specific problem is in the videos other than something kidney related and that he had a surgery and will need another, less serious surgery later on and he should make a full recovery in 3 months. Not sure what it could be as the only kidney surgery I can think of is either a transplant or a Partial nephrectomy due to cancer.
Denis does say everyone should get regular checkups, the doctor says "this can happen to any professional athlete" but does not say what it actually is.
