Incidence and risk factors for urinary tract infection in the first year after kidney transplantation at 108 Military Central Hospital, Vietnam

Abstract

Objective: To determine the incidence of urinary tract infections in kidney transplant patients in our hospital, to identify the microbial pathogens, risk factors for urinary tract infection. Subject and method: Primary kidney transplant patients at 108 Military Central Hospital with full follow-up records in the first year were included in the study. Age, sex, cause of kidney failure, pre-transplantation treatment measures, post-transplantation immunosuppressive regimen were collected. Patient was followed and midstream urine was cultured monthly. Result: There were 94 kidney transplant patients included in our study. Seventy patients (74.5%) were male and 24 (25.5%) were female. One hundred and two episodes of urinary tract infections in 37 patients (39.4%) were reported. Sex (female) (p=0.003; 95% CI: 1.716-14.021), urologic complications (p=0.006, 95% CI: 0.001-0.320) were found as risk factors for UTI in the first year of transplantation. Escherichia coli and Klebsiella pneumoniae were the most frequently isolated pathogens. UTI had no negative impact on short-term graft survival. Conclusion: The results of our study showed a high incidence of UTI in kidney transplant recipients. Infection control methods should be used regularly during post-transplant therapy.
