Background: In the United States, pancreas allograft allocation is strictly regulated. Local centers have the first option to accept an organ, followed by regional and national allocation for those not accepted locally. For a pancreas to be imported, many centers must have previously rejected the organ for transplantation. This study reviews the outcomes of all pancreas allografts transplanted at a single center between January 2003 and November 2007. Early graft function and graft survival were stratified by geographic source of the donor pancreas.
Methods: The records of 247 pancreas recipients and the donors of 11 imported and discarded pancreas allografts were reviewed. Pancreas allograft survival is represented using a Kaplan-Meier survival curve comparing (1) locally procured and imported pancreas grafts and (2) grafts procured by a team from our own center with the grafts procured by another team.
Results: Of the 247 grafts, 184 (74%) were local and 63 (26%) were imported. There were no differences between the two geographic groups in 1-year graft survival (local 91%, import 90%, P=0.76). Similarly, graft survival was similar regardless of whether the organ was procured by our own team or by another center (local team 91%, another team 90%, P=0.96).
Conclusions: Pancreas allografts refused by a large number of centers may still be imported and successfully transplanted without affecting survival results.

Introduction: The management of urinary tract stones, particularly kidney allograft stones, presents unique challenges for kidney transplant recipients because of their prevalence and specific clinical considerations. Here, we describe a case in which percutaneous nephrolithotomy was successfully used to fragment a large kidney allograft stone ≥20 mm in size.
Case Presentation: A 57-year-old woman who underwent ureteroureterostomy post simultaneous pancreas-kidney transplantation presented with gross hematuria after 15 years.

As important immune regulatory cells, whether innate lymphoid cells (ILCs) are involved in liver transplantation (LT) remains unclear. In a murine orthotopic LT model, we dissected roles of ILCs in liver ischemia-reperfusion injury (IRI). Wild type (WT) grafts suffered significantly higher IRI in Rag2-γc double knockout (DKO) than Rag2 KO recipients, in association with downregulation of group 1 ILCs genes, including IFN-γ.

Early failure of a pancreatic allograft due to complete thrombosis has an incidence of approximately 10% and is the main cause of comorbidity in pancreas transplantation. Although several risk factors have been identified, the exact mechanisms leading to this serious complication are still unclear. In this review, we define the roles of the individual components involved during sterile immunothrombosis-namely endothelial cells, platelets, and innate immune cells.

Background: Deceased donor multiorgan transplants utilizing kidneys (MOTs) can improve outcomes for multiorgan recipients but reduces kidneys for chronic renal failure patients.
Methods: We reviewed the Organ Procurement and Transplantation Network database from 2015 through 2019, for adult deceased donor kidney transplants. Recipients were classified as kidney transplant alone (KTA) (n = 62,252) or MOTs pancreas-kidney, simultaneous pancreas-kidney (n = 3,976), liver-kidney, simultaneous liver-kidney (n = 3,212), heart-kidney, simultaneous heart-kidney (n = 808), and "other"-kidney, simultaneous "other" kidney (n = 73).
Sex and gender as predictors for allograft and patient-relevant outcomes after kidney transplantation.

Background: Sex, as a biological construct, and gender, defined as the cultural attitudes and behaviours attributed by society, may be associated with allograft loss, death, cancer, and rejection. Other factors, such as recipient age and donor sex, may modify the association between sex/gender and post-transplant outcomes.
Objectives: We sought to evaluate the prognostic effects of recipient sex and, separately, gender as independent predictors of graft loss, death, cancer, and allograft rejection following kidney or simultaneous pancreas-kidney (SPK) transplantation.
