My kidneys are not functioning at all and my neph said that I would last only two weeks without dialysis, and that was if God was merciful. Without the mercy he said I might last a month but the last two weeks would be the most miserable of my life. I ask him because when I first started hemo I felt that it was too much and I wanted to quit. Everyone assured me that it would get easier, and they were right. It has become easier, but, I STILLHATE DIALYSIS!
I have fluctuated between 12-15% for three years! Another member stayed at 15% for five years before getting a transplant. Each person is different. I hope you FIL stays at this level and gets his transplant soon. And good for his brother for wanting to donate
