My Dad had cancer and they removed it, but now he is worse off than before the surgeries. He is 78 y.o. He is too weak to have a ureter rebuilt or his gallbladder removed. Who should be the director of his care? The urologist, The Kidney Dr? He has constant diarrhea and feels like throwing up a lot. The Doctors really are not giving me a clear path ahead on what to expect or how long my Dad can go on in this condition.
