Introduction

Urinary tract infections (UTIs) are the most common infectious complications among kidney transplant recipients. The highest incidence has been reported in the first 3-6 months after Tx. Recurrent UTIs (three or more UTI episodes within a 12-month period, or two or more within a 6-month period) and infections caused by multi-drug resistant organisms (MDROs) pose a challenge for transplant physicians all over the world.

Methods

We performed a retrospective analysis of patients who underwent kidney transplantation in our centre between 2020 and 2024, to establish the incidence and most common pathogens responsible for UTIs, as well as evaluate the potential risk factors for UTIs. Of a total number of 242 patients, 194 were eligible for analysis. We analysed clinical and microbiological data.

Results

There were 57 patients (29%) who experienced at least one episode of UTI within the first 3 months after transplantation, 34 patients (17.5%) developed UTI in the 3-6 month period after Tx, while 31 (16%) had UTI after 6 months in the first year after Tx. Recurrent infections affected 48 subjects (24.7%). We also investigated the most common pathogens responsible for UTIs in our centre. Klebsiella pneumoniae is the most frequently isolated microorganism, accounting for 28,9% of all UTIs, of which 42,8% were beta-lactamase-producing strains and further 42.8% produced metallo-beta-lactamases, including New Delhi metallo-beta-lactamase 1 (NDM 1). Other detected strains of bacteria included Escherichia coli (13.9% ESBL-negative and 12.3% ESBL-positive), Enterococcus species (18%) and Pseudomonas (8.2%). Less common bacteria included Serratia, Morganella, Acinetobacter and Gram positive bacteria, other than Enterococcus, which accounted for 13.4% of infections. Apart from well known risk factors of UTIs, such as sex, age, BMI, diabetes, we also analysed impact of other parameters, e.g. cold ischemia time, dialysis vintage and type of renal replacement therapy (HD vs PD) on the incidence of UTIs. Only age (p-value = 0.036) and BMI (p-value = 0.014) proved to be statistically significant risk factors of UTIs in the first 3 months after KTx in studied population.

Conclusion

Urinary tract infections are common in the population of kidney transplant recipients, especially within the first 3 months after KTx. UTIs caused by multi-drug resistant strains are a growing problem. Age and BMI are significant risk factors of UTIs.
