“…It remains controversial whether simultaneous DJC cultures are necessary. Some studies have suggested that the results of DJC cultures are consistent with the results of urine culture because bacteria that colonize DJCs can be released into urine; 39 , 40 conversely, some studies have shown that the detection rate was much higher for DJC culture than for bladder urine culture, and the detected pathogens may differ between culture methods. 3 , 41 In this study, patients did not undergo both culture analyses simultaneously; thus, we could not draw a definitive conclusion regarding this point.…”

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.

“…In our study, resistance was significantly higher in patients with a urinary catheter (P = 0.001). A urinary catheter, as well as double ''J'' urinary stents, are responsible for the appearance of NAUTIs [11,12]. The effectiveness of closed urinary drainage systems in preventing UTIs has been established [13].…”

The objective is to evaluate resistance between community-acquired urinary tract infections (CAUTI), nosocomialy-acquired urinary tract infections (NAUTI), and empirical therapy adequacy. E. coli is the predominant pathogen of both CAUTI and NAUTI, followed by Klebsiella spp. in NAUTI and Pseudomonas spp. in catheter-associated urinary tract infections. The highest level of general resistance was found among isolates of NAUTI and catheter-associated UTI followed by CAUTI isolates. Absolute or high level resistance for commonly used empirical antimicrobial therapy was found in catheter-associated UTI and NAUTI while resistance among CAUTI was respectable. Patients with NAUTI as well as patients with catheter-associated urinary tract infections have similar resistance and similar microorganisms isolated as a causative agents, and should not be empirically treated unless the clinical emergency requests.

“…It concerns both the presence of colonization and the type of pathogen cultured from the Double–J catheters and the urine sample. Available data is controversial, therefore it seems that there is a place for further studies in this field [9, 10]. …”

IntroductionThe aim of the trial was to estimate the relationship between colonization of the Double–J catheter, and the microorganisms cultured from urine.Material and methods60 patients, who had Double–J catheters inserted, participated in the study. All the subjects had their midstream urine samples taken prior to the stent insertion and removal. A negative urine culture before catheterization was mandatory to participate in the study. The patients were assigned into three subgroups, according to stenting duration: 1) 20 to 30 days (18 cases); 2) 30 to 90 days (30 cases); 3) longer than 90 days (12 cases). Bacterial and fungal DNA was identified using electrophoresis in polyacrylamide gel with a denaturing gradient (PCR–DGGE). The relationship between the genetic analysis of the catheter and the urine culture was estimated.ResultsUrine cultures were positive in only 8 patients, while Double–J catheter analyses were positive in all cases. In 2 cases one type of microorganism was isolated from the stent surface while the remaining 58 catheters were colonized by more than one pathogen. In three cases fungi were isolated. There were only three types of pathogens cultured from urine specimens. Urine and stent cultures were consistent in 5 cases. In 3 cases urine culture and stent analysis were not consistent.ConclusionsDouble–J catheter retention in the urinary tract is associated with an extremely high risk of bacterial colonization, while the risk of urine infection is about 8–fold lower. There is a great inconsistency between urine infection and catheter colonization, indicating a low predictive value of urine culture for estimating stent colonization.
