Depends on what causes the disease... my mum was born with renal reflux - where the urine doesn't empty properly through the urethra and goes back up into the kidney and they other time begin to fail.....she eventually went onto dialysis for a year and half then a friend of hers gave her a kidney!! Mum would't let me do it because of my kids...

Oops I just re-read your question - no hers wasn't quick onset, but things changed very quickly ...

Hope all is ok xox
