Abstract
Objectives
To investigate the pathogens and potential risk factors for urinary tract
infection (UTI) in patients with retained double-J catheters (DJCs).
Methods
In total, 107 infants and young children with DJCs were included in this
retrospective analysis. Patients were included in the infection group
(n = 30) or non-infection group (n = 77), according to UTI presence or
absence. The species and characteristics of pathogens were investigated, and
the clinical features of the patients were recorded for further
analysis.
Results
Gram-negative bacilli were the most common causative pathogens (69.2%), among
which Escherichia coli was most frequent (38.5%). The
second most common causative pathogens were Gram-positive cocci (28.2%),
among which Enterococcus faecalis was most frequent
(10.3%). UTIs among patients in this study were associated with the
following factors: catheter retention (long-term) (odds ratio [OR] = 2.514,
95% confidence interval [CI] = 1.176–5.373), sex (male) (OR = 2.966, 95%
CI = 1.032–8.529), DJC retention (long-term) (OR = 1.869, 95%
CI = 1.194–2.926), and DJC number (unilateral) (OR = 0.309, 95%
CI = 0.103–0.922).
Conclusions
Infants and young children with DJCs were likely to experience UTIs, mainly
caused by Gram-negative bacilli. Long-term catheter retention or DJC
retention, male sex, and bilateral DJC retention were risk factors for
UTI.
