How long does it take, assuming it does, for your remaining kidney to pick up the load. I went in with a GFR of 105 and creatinine of 1.0. Coming out of surgery my creatinine was 1.8. At six months my labs show a GFR of 44, stage 3, and creatinine of 1.6. My doc wants to do labs again in three months and then again in another three months. Her comment. This may be your new normal. Any thoughts? I am 61. Thanks.
