Transplant nephrectomy - A single-center experience

Abstract

Transplant nephrectomy (TN) is associated with significant morbidity and mortality and influences the outcome of subsequent renal transplantation. The aim of this study was to identify the reasons for TN in a single transplant center in the United Kingdom and to determine the complication rate, effect on relisting and re-transplantation. We studied all the TNs in our center from January 2000 to December 2011. Detailed information including cause of allograft failure and reason for TN were analyzed. Of 602 renal transplants performed at our center during the period of the study, 42 TNs were performed on 38 (6%) patients (24 men and 14 women). The median age of the patients at the time of transplantation who subsequently underwent TN was 56 years (range: 28-73 years) and 71% of the allografts were donated after circulatory death. The mean human leucocyte antigen mismatch for these patients was 2.3. The most commonly used immunosuppression was a combination of prednisolone, mycophenolate and tacrolimus, which was used in 50% of the patients. Twenty-five (60%) of the TNs in this series were for allografts failing during the first month of transplantation. The most common indication for the TN was graft thrombosis (50%), with an overall in-hospital mortality rate of 9.5% and a morbidity rate of 31%. Seven of 19 patients listed underwent successful re-transplantation. Although TN is associated with a risk of significant morbidity and mortality, it does not preclude from listing for re-transplantation. The difficulty of access to complete information about transplant failures and TN highlights the need for a national registry.
