Risk Factors Analysis for Occurrence of Asymptomatic Bacteriuria After Endourological Procedures

INTRODUCTION: Endourological procedures are performed according to the principles of aseptic techniques, jet still in certain number of patients urinary tract infections may occur. Considering the risk of urinary tract infection, there is no unique opinion about the prophylactic use of antibiotics in endourological procedures. GOAL: The objective of this study was to determine the connection between endourological procedures and occurrence of urinary infections and to analyze the risk factors of urinary infection for patients who were hospitalized at the Urology Clinic of the Clinical Center University of Sarajevo CCUS. MATERIALS AND METHODS: The research was conducted as a prospective study on a sample of 208 patients of both genders, who were hospitalized at the Urology Clinic of the CCUS and to whom some endourological procedure was indicated for diagnostic or therapeutic purposes. We analyzed data from patient’s histories of illness, laboratory tests taken at admission and after endourological procedures, also surgical programs for endoscopic procedures. All patients were clinically examined prior to endoscopic procedures while after the treatment attention was focused to the symptoms of urinary tract infections. RESULTS: Statistical analysis of the tested patients indicates that there is no significant difference in the presence of postoperative, compared to preoperative bacteriuria, which implies that the endourological procedures are safe procedures in terms of urinary tract infections. Preoperatively, the most commonly isolated bacteria was Escherichia coli (30.9%) and postoperatively, Enterococcus faecalis (25%). Statistically significant effect on the occurrence of postoperative bacteriuria has preoperative bacteriuria, duration of postoperative catheterization, and duration of hospitalization. CONCLUSION: In everyday urological practice, it is very important to identify and control risk factors for the development of urinary infection after endourological procedures, with main objective to minimize occurrence of infectious complications.
