I never did have my kidney removed, but I too as a 7 year old child was on the waiting list for kidneys. They told me if I did make it to childbearing age, I would def. Need new kidneys after child birth. I have never again had trouble with them. I get some pains, and I know to force fluids, and I spill protein(white blood cells, albumin) all the time. But they just keep on going. I am now 43 years old and still doing fine.
I know many pple live with only one and never know the difference. Maybe they could just give her time, the kidney might get better, if they can stop the blockage.
I am so sorry to hear about this and I will be praying. Get your church praying, or momma's church--you know what I mean? .God bless your little baby--hope we hear good news about her soon.
And always try to get a second opinion when faced with something so life changing!! Just my opinion.
Always
