Kidney disease and transplant
So I'm writing a book setting place in England (Sheffield/London) in the 2010's. My main character is a young 18 years old girl. For the need of the plot, I need her to have a kidney disease (That she had before the beginning of my story), bad enough so at one point it requires a transplant, but so she can be relatively in good shape for the first part of the story (three month or ich before the transplant is absolutely needed, where she goes out and live her life pretty normally, with or without medication but without going to hospital, even if there is side-effect). This disease can be compound by the fact that she didn't go to see a doctor for the 3 months of the plot.
At this point of this story, she would receive a kidney from her dad. I was wondering if maybe someone could help me in :
1) Finding a believable disease
2) Explaining why her father can give her his kidney but not her mother (It has to be the father, because of the plot... But I can't find a clear article on transplant compatibility relative to kidney...)
3) Be right in the way I describe the recovery from the transplant for both the girl and her dad.
At this point, I mostly do internet research. I started with the wikipedia articles on kidney, then kidney disease, then specific kidney disease, I checked the ref of all thoses articles and I went to the nearest library to medical stuff BUT! Thing is... Those articles are too technicals. There a lot of medical terms that I don't get and I kind of drowning in infos.
Any help or testify are welcomed. Thank you for your future input!
