    Videourodynamic studies (VUS) can evaluate complex voiding dysfunctions. A cluster of urosepsis cases linked to P. aeruginosa suggests potential contamination risks during VUS procedures.

    Area of Science:

    • Urology
    • Infectious Disease
    • Medical Device Safety

    Background:

    • Videourodynamic studies (VUS) are crucial for diagnosing complicated lower urinary tract dysfunctions.
    • These studies involve invasive procedures like catheterization and pressure measurements.

    Purpose of the Study:

    • To investigate a cluster of urosepsis cases occurring after VUS procedures.
    • To identify potential sources of infection associated with VUS.

    Main Methods:

    • Retrospective analysis of five urosepsis cases following VUS.
    • Microbiological cultures of patient samples (blood, urine) and equipment.
    • Temporal correlation analysis between VUS procedures and infection onset.

    Main Results:

    Related Experiment Videos

    • Five cases of urosepsis were identified within a specific timeframe following VUS.
    • Pseudomonas aeruginosa was isolated from three patients and the VUS apparatus.
    • The stopcock-tubing-syringe apparatus was identified as a potential reservoir for P. aeruginosa.

    Conclusions:

    • The VUS procedure may be associated with an increased risk of urosepsis.
    • Contamination of the VUS apparatus, specifically the fluid pathway, is a likely source of P. aeruginosa infection.
    • Recommendations for equipment sterilization and procedural modifications are warranted to mitigate infection risk.
