Hello doctor, my 53 year old dad had been diabetic since 30 years, now he is in kidney failure. Now kidney specialist has advised for kidney transplant. What are the treatment options for patient with kidney failure other than kidney transplant and kidney transplant is better than other treatment options? Are there different kinds of kidney transplants? What is rejection? What are the chances that a transplanted kidney will continue to function normally? Will I need to follow a special diet?
