THE kidney trade is a global phenomenon; it is present in both the developing and the developed world. Since the introduction of the immuno-suppressant drug Cyclosporine in the early 1980s, organ transplantation has become a relatively safe operation. More and more patients suffering from End Stage Renal Disease opt for kidney transplants instead of remaining on dialysis. The result? In many parts of the world, the demand for kidneys far outweighs the supply. Brokers have stepped in, offering kidneys for sale to cover the deficit.
