Transplant nephrectomy after graft failure: is it so risky? Impact on morbidity, mortality and alloimmunization

Abstract : Purpose To determine the impact of transplant nephrectomy on morbidity and mortality and HLA immunization. Methods All patients who underwent transplant nephrectomy in our centre between 2000 and 2016 were included in this study. A total of 2822 renal transplantations and 180 transplant nephrectomies were performed during this period. Results The indications for transplant nephrectomy were graft intolerance syndrome: 47.2%, sepsis: 22.2%, vascular thrombosis: 15.5%, tumour: 8.3% and other 6.8%. Transplant nephrectomies were performed via an intracapsular approach in 61.7% of cases. The blood transfusion rate was 50%, the morbidity rate was 38% and the mortality rate was 3%. Transplant nephrectomies more than 12 months after renal transplant failure were associated with more complications (p = 0.006). Transfusions in the context of transplant nephrectomy had no significant impact on alloimmunization. Conclusion The risk of bleeding, and therefore of transfusion, constitutes the major challenge of this surgery in patients eligible for retransplantation. Even if transfusions in this context of transplant nephrectomy had no significant impact on alloimmunization, this high-risk surgery, whenever possible, must be performed electively in a well-prepared patient.
