Everyone is surprised at how long my dad lasted without dialysis, but he always told me that he was still passing a little bit of urine, although it was very slow and tedious. Could this have been why? Hospice nurses were amazed as well as doctors that he was hanging on so long. We thought at first that it was his strong will to live and then assumed he was waiting for my brother to fly out from Florida.....? All of the above may have had something to do with it, but in all honesty we are just grasping at straws. It just wasn't his time I suppose......? Dad was indeed a fighter with a strong heart and good set of lungs. His only downfall was the kidneys.I hope this helps in some way to answer your questions. Thanks for responding:)
