ABSTRACT
【Objective】 To investigate the independent risk factors of urinary tract infection (UTI) in recipients under-going renal transplantation of donation after brain death (DBD), so as to provide a theoretical basis for the prevention and control of postoperative UTI. 【Methods】 A retrospective study was conducted for recipients who received renal transplantation of DBD in our hospital during Jan.2021 and Dec.2021. The recipients were divided into the infection group (n=26) and non-infection group (n=74) according to the incidence of UTI 3 months after operation. The risk factors of UTI were identified with univariate and multivariate analyses. 【Results】 The incidence of UTI was 26%. Univariate analysis showed that gender, postoperative urinary fistula, time of indwelling catheter and time of indwelling double J tube were the influencing factors of UTI (P<0.05). Forward stepwise regression analysis showed time of indwelling double J tube (OR=1.086,95%CI:1.003-1.177,P=0.042) and time of indwelling catheter(OR=4.687,95%CI:2.064-10.645, P<0.010) were the independent risk factors of UTI (P<0.05). 【Conclusion】 The time of indwelling catheter and time of indwelling double J tube are the independent factors of UTI after renal transplantation of DBD.
