@paulinlouisiana Two questions I have for you, are: How long have you been doing the "wait and watch" with this lesion? The activity of it may be telling to your team. Also, what is your eGFR? Yes, we can live with one kidney, if the remaining one is healthy. For example, in my case, I also am on a "wait and watch" with my lesion, but my eGFR is only 24%; a nephrectomy will put me onto dialysis.

Were you able to get an appt with your local dr to discuss things? If your town has opened up, you might consider taking a second person with you, to help listen to the details. As @rosemarya said, writing questions and notes down helps. For me, I sometimes have them repeat what they said because I was taking notes and missed something.
