BARBA ABAD, J. et al. Surgical complications in kidney transplantation and their influence on graft survival. Actas Urol Esp [online]. 2010, vol.34, n.3, pp.266-273. ISSN 0210-4806.

Objectives: To analyze surgical complications in kidney transplantation and their influence on graft survival. Materials and methods: A retrospective analysis was made of the early and late surgical complications occurring in 216 consecutive kidney transplants performed at our institution and their influence on graft survival. Results: At least one surgical complication occurred in 82 (38%) of the 216 transplantations, and 68 (31%) required some type of repeat surgery, 23 in the early postoperative period and 45 more than 3 months after surgery. Mean follow-up was 48 months (SD +/-33.4), and median follow-up 48 months (range, 0-166 months). No recipient or donor factors predisposing to surgical complications were found. Graft survival was significantly shorter in patients with surgical complications [3- and 5-year survival rates of 86% (95% CI 83%-89%) and 78% (95% CI 73%-82%) as compared to 92% (95% CI 90%-94%) and 88% (95% CI 85%-91%), p:0.004]. Early repeat surgery, venous thrombosis, and wound infection were among the complications having an independent influence on graft survival. A multivariate analysis of graft survival in the whole group showed early repeat surgery to be a factor with an independent prognostic value (OR: 4.7; 95% CI 2.2-10, p<0.0001). Delayed function and donor age older than 60 years were the other independent influential factors. Conclusion: Surgical complications have an influence on graft survival. The need for early repeat surgery, delayed function, and donor age older than 60 years are independent predictors of graft survival.
