%X <B>UNASSIGNED: </B>To investigate the microorganisms responsible for double J stent (DJS) colonization, bacteriuria, and the drug susceptibility of the isolates. We also tried to determine factors associated with stent colonization, such as indwelling time, sex, age, and comorbidities.<BR><B>UNASSIGNED: </B>This study is a prospective analysis of patients following DJS ablation. A total of 155 patients from our institution were enrolled in this study between January 2023 and May 2023. Bladder urine was collected in a sterile container prior to stent removal for bacteriological exam. The removed stents were divided into three parts: top (Renal), middle (Ureteral), and bottom (Bladder); 3 cm pieces from each part were taken and placed in a sterile test tube for bacteriological investigation.<BR><B>UNASSIGNED: </B>The mean age of patients with positive stent culture was 61.17±12.82 versus 55.94±10.32 when stent culture is negative, which is statistically significant P=0.016. Diabetes and bacteriuria are both correlated with DJS contamination with P<0.001 in the two cases. The mean duration of the use of DJS in patients with colonized stent culture is 6.45±2.98 months versus 4.06±2.20 months for the other patients; the difference is statistically significant P<0.001. The most commonly isolated pathogens on stents were Gram-negative bacilli (53.2%), dominated by Enterobacteriaceae in 19 cases (55.2%).<BR><B>UNASSIGNED: </B>Indwelling time is the only unanimous factor of stent colonization in literature, so we recommend using DJS only if necessary and to remove it as soon as possible.
