Studying predisposing factors for urinary tract infection incidence after lower urinary endoscopy .
Abstract
Introduction: Cystoscopy is a fundamental procedure in the diagnosis and management of a wide range of urinary tract diseases. It involves the use of instruments through the urethra, which is considered the most common route for urinary tract infections.
.
Aim: To study the risk factors that contribute to the incidene of infection after performing cystoscopy, in order to reduce them.
Materials and Methods: This was a prospectiveanalytic cohort study involved 150 patients who underwent lower urinary endoscopy for various indications at Tishreen University Hospital- Lattakia-Syria during the period between May 2023 and May 2024. Patients were divided into two groups according to the occurrence of urinary tract infection after procedure: group 1 with urinary tract infection (12 patients), and group 2 without infection(138 patients), in which demographic and endoscopic characteristics were compared between groups.
Results: A total of 150 patients, 98 males (65.3%) and 52 females (34.7%) with a mean age of 59.87±17.6 years were included in the study.There were no significant differences between two groups regarding of gender, smoking, hypertension, number of endoscopic procedures, indication of procedure and endoscopic findings(p>0.05). Urinary tract infection was significantly more frequent in age group older than 50 years(75% versus 25% in other groups,p:0.04), presence of diabetes mellitus(41.7% versus 20.3%,p:0.002), cystoscope Storz Fr 20( 66.7% versus 33.3% in Fr 17,p:0.02), duration of procedure longer than 5 minutes(83.3% versus 16.7%,p:0.0001), hospitalization cases(58.3% versus 41.7%,p:0.0001) and presence of urinary catheter(66.7% versus 33.3%,p:0.0001). Diabetes mellitus(OR: 2.3[1.1-8.4], p:0.001), presence of urinary catheter (OR: 5.8[1.4-11.8], p:0.0001) and longer duration of procedure(OR: 3.3[1.7-12.4], p:0.007) represented an independent risk factors for development of urinary infection.
Conclusion: : The current study demonstrated the importance of presence high index of suspicion for urinary tract infection after lower urinary endoscopy especially in presence of risk factors for early diagnosis and treatment to improve final outcome of patients.
