I don't know, but there isn't to many diseases that you have to prepare for with surgery before you actually start treatment....
Lola - Sounds like Otto is very active, therefore I would push for him getting the fistula. With the catheter he has to limit any kind of sweating or major activity because the catheter and site is more likely to get infected. Rob had 5 fistulas because he was active and sweat a lot, so he got more infections due to this, even one that landed him in the hospital for a week.He will need a good 5 months for the fistula to mature, so push for it now. It sucks, it took Rob a long time to get up the courage to deal with dialysis and after the catheter, he wished he had one put in sooner.Good luck, I know this is hard for all of you!!
