[/INST] Hello and welcome to Chat Doctor. As a Urologist and transplant surgeon, i can understand your anxiety. What you should realize is, that a doctor is not God. He's a man like you. Only God decides our future. Every day, thousands of child Chat Doctor. But their parents and family, face it with courage, not taking own lives. If the blood groups don't match, transplanted kidney will be rejected. Kidney failure is treated by a dialysis or a kidney transplant. But latter best. All clearances for doing transplant, must be cleared by a board, to be safe. If you've any doubts, you may send all reports to me, as a direct question. </s>
