      ]. In this article, the authors attempt to determine whether kidney transplant (KT) is best performed before or after bariatric surgery (BS). The primary outcomes of interest were patient and graft survival, and secondary outcomes were postoperative complications and efficacy of weight loss. The authors studied 22 patients in the KT first group and 34 in the BS first group. They found that death/uncensored graft survival in the KT first group was significantly higher than in the BS first group (90.9% versus 71.4%; P = .009), and there was no significant difference in 1-year total weight loss, 1-year percentage of excess weight loss, or the incidence of postoperative complications between the KT and BS first groups. The authors did not mention whether any of the patients awaiting KT died while waiting for transplant or while waiting for a suitable donor. The authors concluded that both pre- and post-transplant BS is effective and safe and that each transplant candidate should be considered in detail to determine the optimal timing of BS.
