Risk Factors for Urinary Colonization in Patients with Double J Catheters Implanted for Treating Obstructive Urolithiasis

Background: The highlighting of possible risk factors for urinary colonization in patients with obstructive urolithiasis that needed double J catheters implanted to preserve renal function. Methods: We performed a descriptive, retrospective study, carried out in the Urology Department of the Bucharest Central Military Hospital, between January 2020 and January 2022 and included 168 patients with urolithiasis who required the insertion of double J catheters. We studied the bacteriological profile, using both urine and JJ catheter samples. Results: We obtained a double J catheter colonization rate of 32% (54 patients) and 29% of urinary colonization (49 patients). The rate of urinary colonization is higher in patients with colonized ureteral catheters regardless of sex, age, and associated comorbidities. At the same time, we noticed an increased rate of urinary colonization in patients associated with diabetes, hypertension, and chronic kidney disease. Conclusions: The prevalence of urinary colonization in patients with double J catheters was 29%. The colonization of the JJ catheters, as well as the association with chronic diseases, such as diabetes, hypertension, and CKD (Chronic Kidney Disease), show an increased risk of urinary colonization.
