My 55 year old sister in law has stage 5 kidney disease and had surgery to make a fistula on the 12th of October. The Fistula is not developed enough for dialysis. She is drinking and peeing but she is having stomach pains and doesn t really have an appetite. I told her if she doesn t eat we are going to ER for a Catheter to be installed in her neck and get dialysis done immediately. She came down to eat, but not a lot. Her face looks a little swollen. She doesn t want to go to ER, how long before the kidneys will shut down and should I make her go? She has 6% kidney function after her last blood work was done.
