Abstract
Introduction: Urinary tract infection (UTI) is one of the most common infection following
kidney transplant surgery.
Objectives: This study was aimed to evaluate the effect of UTI after transplant on patients and
graft survival rate.
Patients and Methods: This study was cross-sectional and the data collected retrospectively.
Kaplan-Meier method was used to calculate the survival rate of patients and log-rank test
was applied to compare the survival curves. Cox regression model was applied for modeling
the factors affecting survival rate. The data were analyzed using SPSS version 19. The level of
significance considered less than 0.05.
Results: The mean duration of follow-up in infected and non-infected patients following
kidney transplantation surgery were 53.78±24.5 months and 67±40.8 months, respectively.
Ten-year survival rate in infected by UTI and in non-infected by UTI were 78±0.03% and
89±0.02%, respectively. Also, 10-year graft survival rate in infected patients and in noninfected
patients were 71±0.03% and 88±0.02%, respectively. Log-rank test showed a
significant difference between infected and non-infected patients regarding graft survival
rate (P<0.001).
Conclusion: The results showed that the survival rate of patients was different in infected and
non-infected patients. This finding indicated the importance of follow-up in patients with
infection following kidney transplant surgery.
