%X Introduction. The management of a failed primary allograft remains unclear and the evidence of the effect of transplantectomy to future transplants conflicting. Aim of this study is to review the impact of failed primary graft nephrectomy on future transplants. Materials/Methods. Retrospective study of 101 patients retransplanted in a single institution. Median follow-up was 68 months. Patients were divided into two groups; G1 ( ) was the nephrectomy group; G2 ( ) was the graft in situ group. The patientsĄ¯ and second graft survival were analysed with the Kaplan-Meier method. The patientsĄ¯ and transplant characteristics were analyzed with studentĄ¯s -test. The retransplant risk factors and the risk factors for multiple transplants were obtained via a logistic regression model. Results. The odds of second graft loss post-transplantectomy were high (OR = 5.24). Demographics, HLA mismatch and first graft rejection rates were similar among the two groups and did not affect the outcome. Transplantectomy accelerated the loss of a future failing graft. Multivariate analysis showed transplantectomy as independent risk factor for second allograft loss. Transplantectomy and younger age are significant independent risk factors for future multiple transplants. Conclusion. Transplantectomy of the failed primary graft is an independent risk factor for retransplant loss and for multiple renal transplants. 1. Introduction The high success rates of primary kidney transplants and longer graft life due to better immunosuppression have led to a larger number of transplant patients living longer and inevitably a larger patient population with failed primary kidney transplants [1, 2]. The same level of successful outcomes has not been achieved for patients who are retransplanted in terms of lifespan of the second allograft [2, 3]. There has been little research looking at retransplantation in patients with a failed primary kidney transplant and how to achieve the best outcome. It is still very controversial when the primary kidney transplant fails how best to manage these patients. Failed allografts in situ still stimulate immunoreactivity and are known to cause a chronic inflammatory response as measured by an increase in CRP, ESR, EPO resistance, hypoalbuminaemia, and malnutrition [4, 5]. Ayus et al. looked at 10,000 patients with a failed primary allograft in the United States and found that there was an improvement of morbidity and mortality in the patient group where the allograft was removed [6]. These benefits of graft nephrectomy notwithstanding, leaving the primary
