Abstract
Introduction: Infections associated with catheter in the upper urinary tract (CUUT), which include the double-J stent and the percutaneous nephrostomy (PCN) tube, get particularly infected in patients with specific risk factors for developing an infection.
Methods: A retrospective observational study was carried out by compiling data from the hospital information system of a tertiary care center from 2019 to 2021 to evaluate infections in patients with catheter in the upper urinary tract.
Result: A total of 200 pus samples of double-J stent (96 pus samples) and PCN tube (104 pus samples) were included in our study. Among patients with nephrostomy tube, the most frequently isolated microorganisms were Escherichia coli, followed by Pseudomonas spp. In those with a double-J stent, Pseudomonas aeruginosa, followed by E. coli were the most commonly isolated microorganisms. We found 55.72% of cases of Enterobacteriaceae-producing carbapenemases in patients with a percutaneous catheter. 66.07% of Enterobacteriaceae in patients with double-J and nephrostomy stents are extended-spectrum beta-lactamase-producing bacteria. The percentage of cultures with multiple-drug resistance (MDR) microorganisms was 38.54% in patients with double-J stents and 37.75% in nephrostomy tubes. The presence of prior urinary tract infection (P = 0.010), presence of urinary catheter before admission (P = 0.005), increased time with single urinary catheter in-situ (P < 0.001), and increased length of hospital stay (P = 0.036) were risk factors for isolation of MDR microorganisms.
Conclusion: Pseudomonas spp. and Pseudomonas aeruginosa are commonly infecting both the CUUT. E. coli infections are more commonly infecting the nephrostomy tubes. MDR microorganisms are frequent, mainly in patients with prior urinary tract infection, presence of urinary catheter before admission, and prolonged use of a single catheter.
