I am a home care nurse, and I have never run into this question before. I know of a close friend of the family that had one kidney removed because of cancer. He recently had some issues with a blockage in his ureter. Before he had his surgery, they told his wife that if they found cancer in the remaining kidney, they would remove that also. Luckily, everything turned out fine. I just have never heard of anyone relying soley on dialysis, without any kidneys. Has anyone actually seen a patient with both kidney's removed?
