Oh I’m so grateful for the response. I feel very alone in this. He has had CKD for a decade at least. So did my grandmother. I am not sure we really know why. The cancer was found incidentally last month when he was admitted to the hospital for a UTI. His baseline eGFR has been in the mid to low 20s for a long time. But the UTI plunged him to a 9. They released him when it got to 20, but it isn’t holding steady. So I am unsure what to do between now and the oncology appointment.
