Abstract: Ｏｂｊｅｃｔｉｖｅ：Analyze the relationship between metabolic syndrome (Mets) and delayed graft function (DGF), and prognosis of patients after renal transplantation.
Ｍｅｔｈｏｄｏｌｏｇｙ：A retrospective analysis of the clinical data of 415 patients who underwent allograft renal transplantation at the 900th Hospital of the Joint Service Support Force of the Chinese Peoples Liberation Army from May 2011 to October 2019. The patients were divided into DGF group and nonDGF group relationship among the age of the donor, cause of death, BMI, terminal SCr, gender, age, transplanted kidney volume／body surface area (RV／BSA), cold ischemia time(CIT), warm ischemia time(WIT), hepatitis B, BMI, diabetes, hyperlipidemia, hypertension, Mets and postoperative DGF and its impact on the prognosis of the recipients were analyzed.
Ｒｅｓｕｌｔｓ：Univariate analysis suggested that cause of death, terminal SCr, cold ischemia time, warm ischemia time, gender, diabetes, hyperlipidemia, BMI, and Mets were risk factors for DGF after renal transplantation (P<005); single factor analysis results which had statistical significance were included in multivariate logistic regression analysis, and the results suggested that terminal SCr(OR=4520,95％CI 2585～7904,P<0001), CIT(OR=2530,95％CI 1273～5028,P=0008), WIT (OR=2249,95％CI 1302～3887,P=0004), hyperlipidemia(OR=2165,95％CI 1078～4348,P=0030)and Mets (OR=7393,95％CI 2243～24368,P=0001) were independent risk factors for DGF after renal transplantation; univariate and multivariate Cox regression analysis suggested that terminal SCr(HR=2269,95％CI 1128～4564,P=0022), CIT (HR=2082,95％CI 1007～4308,P=0048), Mets (HR=5744,95％CI 1215～27153,P=0027) were independent risk factors for renal allograft loss; preoperative patients combined Mets with were more likely to be complicated by kidney stones, poor incision healing, and lung infections.
Ｃｏｎｃｌｕｓｉｏｎ：Patients with Mets had a significantly increased risk of DGF and worse prognosis after kidney transplantation.
