Abstract

Background: Over the last decade, there has been a steady increase in the number of patients diagnosed with end stage renal failure (ESRF). Renal transplant remains the best available treatment for ESRF. The aim of this study is to assess the surgical outcomes following renal transplantation in a single tertiary centre in Aotearoa New Zealand.

Methods: A retrospective observational study was performed in Christchurch Hospital. All live-related and deceased donor adult renal transplants performed between 1 January 2009 and 1 January 2023 were included in the study. Patients were identified from the local transplant database (Proton) and data were extracted from both electronic and hardcopy records.

Result: There were 227 live-related and 150 deceased donor renal transplants performed over the study period. Median BMI in the study cohort was 27 kg/m2. The most common aetiology of ESRF was glomerular disease. Obese (BMI 30-40 kg/m2) patients had a higher incidence of post-operative complications. Ethnicity was shown to be associated with a higher incidence of post-operative complications. This was only statistically significant in the Pacific Islander group (P = 0.013). Live-related donor graft survival was 97% at 1 year and 93% at 5 years while deceased donor graft survival was 95% at 1 year and 92% at 5 years.

Conclusion: This study showed that graft outcome in our cohort was comparable to international data. However, further studies are needed to assess whether specific ethnic groups are truly linked to a higher incidence of post-operative complications.
