A Retrospective Cohort Study to Identify the Risk Factors for Urinary Tract Infection After Office Procedures

Area of Science:

• Urology
• Infectious Disease

Background:

• Urinary tract infections (UTIs) are common, and post-procedural infections can complicate diagnostic tests like cystoscopy and urodynamic studies (UDS).
• Identifying risk factors for post-procedural UTIs is crucial for patient management and potentially implementing prophylactic measures.

Purpose of the Study:

• To determine the incidence of UTIs after office cystoscopy and UDS in women.
• To identify specific risk factors associated with developing a UTI post-cystoscopy or UDS.

Main Methods:

• A retrospective cohort study was conducted on 274 female patients undergoing office cystoscopy or UDS.
• Modified Poisson regression analysis was employed to identify risk factors for post-procedural UTIs.

Main Results:

• A total of 9 out of 185 patients (4.8%) developed a UTI after cystoscopy. Significant risk factors included a history of recurrent UTI (RR 7.51) and interstitial cystitis (RR 4.56).
• Ten out of 192 patients (5.2%) developed a UTI after UDS, with no significant risk factors identified.
• Patients with recurrent UTIs had a 13.7% post-cystoscopy UTI rate, and those with interstitial cystitis had a 25% rate.

Conclusions:

• Recurrent UTIs and interstitial cystitis are significant risk factors for post-cystoscopy UTIs in women.
• The incidence of UTIs following UDS is low, and further research may guide prophylactic strategies for high-risk patient groups.
