    Area of Science:

    • Urology
    • Clinical Microbiology

    Background:

    • Bacteriuria screening is crucial in urological practice.
    • Accurate and rapid diagnostic tools are needed for patient management.

    Purpose of the Study:

    • To evaluate the clinical utility of a semiautomated bacteriuria screening device.
    • To assess the device's performance against standard urine culture methods.

    Main Methods:

    • 1,300 consecutive urine specimens were analyzed.
    • Device results were compared with semiquantitative urine cultures.
    • Sensitivity and predictive values were calculated at different bacteriuria thresholds.

    Main Results:

    • The device achieved 91% sensitivity for >10(5) CFU/ml and 81% for >10(4) CFU/ml.

  • Negative predictive value was high (99% for >10(5) CFU/ml, 96% for >10(4) CFU/ml).
  • A small percentage (2%) of screenings failed due to filter clogging.

    • Conclusions:

    • The semiautomated device demonstrates reliable performance for bacteriuria screening in urology.
    • Its high negative predictive value is beneficial for ruling out infection.
    • The device can aid in safe urological procedures and efficient patient care.
