Protective Impact of the Kidney in SPK Transplants – Mechanisms for Improved Outcomes Compared with Solitary Transplants.
E. Finger, T. Dunn, A. Kukla, V. Kirchner, R. Kandaswamy.
Surgery, University of Minnesota, Minneapolis, MN.
Purpose: Outcomes for SPK txps are superior to solitary pancreas txps. The basis for this difference is unknown. We sought to identify the biologic mechanism…
