Dr. Sandip Kapur
Chief, Division of Transplantation Surgery
Director, Kidney and Pancreas Transplant Programs
NewYork-Presbyterian/Weill Cornell
Associate Professor of Surgery
Weill Cornell Medical College

A leading pioneer of advanced techniques in transplantation surgery, Dr. Kapur specializes in kidney, whole organ pancreas and islet cell transplantations. He performs laparoscopic donor nephrectomies, and was the first and only surgeon in the tri-state area to perform a successful islet-cell transplant to cure Type 1 diabetes. Dr. Kapur also performs vascular access surgery and general surgery on renal failure patients. Dr. Kapur coordinated one of the nation’s first never-ending altruistic donor (NEAD) “chain” renal transplants, which may transform the way transplants are performed in the United States.

Dr. Kapur is a nationally recognized pioneer in developing innovative strategies that allow more recipients to receive successful transplants in instances where transplants would be contra-indicated at most other centers. These include a desensitization program that allows donors and recipients whose blood isn't compatible in a test tube to undergo successful transplants, and the ABO program, which enables a recipient to receive a kidney from a donor whose blood type doesn’t match. The ABO program is only being offered by a handful of transplant centers in the United States.
