Abstract:
                                      OBJECTIVE To explore the incidence, influencing factors and etiological characteristics of postoperative urinary tract infection in recipients undergoing renal transplantation of donation after cardiac death(DCD) so as to provide theoretical basis for development of prevention measures for postoperative urinary tract infection in the recipients undergoing renal transplantation of DCD. 
METHODS A retrospective survey was conducted for the recipients who received the renal transplantation of DCD in the First Affiliated Hospital of Shandong First Medical University from Jan 2016 to Dec 2018, the clinical data were collected from the patients, and the univariate analysis and multivariate logistic regression analysis were performed for the influencing factors and etiological characteristics of the postoperative urinary tract infection in the recipients undergoing the renal transplantation of DCD. 
RESULTS Of totally 375 recipients who received the renal transplantation of DCD, 60 had urinary tract infection, with the infection rate 16.00%.The univariate analysis showed that the gender, age, diabetes mellitus, duration of urinary catheter indwelling, acute rejection, delayed graft function(DGF) and urine white blood cell counts were the influencing factors for the postoperative urinary tract infection in the recipients undergoing renal transplantation of DCD.The multivariate logistic regression analysis indicated that the duration of urinary catheter indwelling and DGF were the independent influencing factors for the postoperative urinary tract infection in the recipients undergoing renal transplantation of DCD.Totally 88 strains of pathogens were isolated from urine specimens of 60 recipients undergoing renal transplantation of DCD, 78(88.64%) of which were gram-negative bacteria. 
CONCLUSION The incidence rate of postoperative urinary tract infection is high among the recipients undergoing renal transplantation of DCD, there are a variety of influencing factors, and it is necessary for the hospital to make clear of the risk factors and take comprehensive intervention measures in early state so as to control the urinary tract infection.
