A simple technique to harvest two kidneys from one donor rat for transplantation.

Kidney transplantation in rats is a widely used and well established model in transplantation immunology and preservation research. With the conventional method, only one kidney is harvested from the donor rat. We developed a technique to harvest two kidneys separately from one donor, subsequently both kidneys were successfully implanted into two recipient rats. This technique which leads to a reduction of the number of experimental animals used is discussed in detail.
