Medical science has taken a long stride. Advancement in surgery has brought a revolution in the lives of human beings. People have been brought back to life from the jaws of death through prompt medical help. Organ transplantation and organ regeneration are some of the new medical procedures. They are frequently used to save human lives.

Instances of kidney transplantation are quite common.

I remember one incident where a kidney transplantation saved a human life. There was an appeal from a kidney patient in all the leading newspapers. Both of his kidneys had failed. Prompt transplantation of a healthy kidney could save his life. At last, the man found a donor. The operation was successful. The organ transplantation brought him back to life from the brink of death.
