The Prevalence and Risk Factors for Urinary Tract Infection in Kidney Transplant Recipients in the First Year After Transplantation

Background: End-stage renal disease (ESRD) needs replacement therapy and most often, kidney transplantation is the best therapeutic option. Urinary tract infection (UTI) is one of the most important complications after renal transplantation that affects transplantation outcomes. Objectives: This study aimed to define the incidence rate, UTI risk factors among kidney transplant recipients, and causative organism of UTI and their antibiotic susceptibility. Methods: In this cross-sectional study, we collected clinical, demographic, and laboratory data from 268 transplant recipients in Ali-Asghar Hospital from 2011 - 2018. Data collected from patients were analyzed with SPSS software version 25. Results: According to the results, 50 (18.7%) had UTI in the first year after renal transplantation. Female gender and underlying cause of renal failure were predisposing factors for UTI. The most common causative organism was Escherichia coli (58.4%). The antibiotic susceptibility results showed nitrofurantoin and meropenem as the most effective antibiotics for E. coli. Conclusions: The UTI was more common in women and patients with analgesic nephropathy and lupus nephritis. The most common causative organism was E. coli and meropenem and nitrofurantoin were the most effective drug choices.
