Is There a Role for Double J Stent Culture in Contemporary Urology?

Abstract

Introduction: To present the incidence of bacterial colonization on ureteral double J stents (DJS); isolate the uropathogens; define the rate of multi-resistant bacteria strains (MRBS) and present their clinical importance. Materials and Methods:<unterline></unterline> The whole body of 105 DJSs was examined for the presence of uropathogens. Results: The main etiology for stent placement was lithiasis (57.1%). The most frequently cultured microorganisms were staphylococcus (28.6%). Forty-four stents hosted MRBS. 25 (23.8%), 10 (9.5%) and 8 (7.6%) of the patients were affected by malignancy, diabetes mellitus and chronic renal failure respectively. Apart from the female gender, none of the examined factors (age, duration of stenting and chronic diseases) was correlated with the colonization or the presence of MRBS. Eleven of the 61 stented patients (18%) who were operated upon developed a febrile urinary tract infections (UTI). In 7 of them the stent hosted MRBS (63.6%). After taking into consideration the sensitivity report, we altered our initial empirical antibacterial prophylaxis to targeted antibacterial treatment in the patients with MRBS with rapid remission of their infection and no urosepsis event. Conclusion: The knowledge of bacteriologic flora of DJS can be very helpful in an evidence-based prophylactic and therapeutic practice. Stent examination could be recommended in high-risk cases of developing UTI and sepsis after a urologic operation. © 2016 S. Karger AG, Basel. All rights reserved.
