My neph wanted me to get my fistula at around 20-21, and I wish I had listened to him! I ended up getting it at 8, or maybe it was 6 since I had a blood test hours after the surgery. The next day, I went in for one of those chest caths MM mentioned above, and by Friday of that week, I was hooked up to a machine. Had to build the fistula up, started using it in June (surgery was in April) got cath removed in early August. My GFR never bounced back up once it started going down. I was hoping it would! I honestly thought I had more time, but alas, for me, that was not the case. A year ago on Dec 1st, I went in for a transplant eval w/a gfr of 19. By March, it was 13, in April - 8. Then in less than one week, it dropped down to 6. Now I am recovering from my transplant surgery that I had on 11/23! A very kind and very healthy relative stepped up and offered to donate to me. I am truly blessed.KarenInWA
