    Computerized tomography (CT) may miss bladder ruptures in trauma patients. Retrograde cystography remains the most reliable diagnostic test for suspected bladder rupture, even with subtle CT findings.

    Area of Science:

    • Radiology
    • Urology
    • Trauma Surgery

    Background:

    • Computerized tomography (CT) is frequently the initial imaging modality for patients with blunt abdominal and pelvic trauma.
    • Bladder rupture is a potential complication of such injuries, necessitating accurate and timely diagnosis.

    Observation:

    • A prospective study compared the diagnostic accuracy of CT and retrograde cystography for bladder rupture in trauma patients.
    • Patients with blunt trauma, gross hematuria, or pelvic fractures underwent both CT and retrograde cystography.
    • A urethral catheter was used to facilitate bladder filling during CT scans.

    Findings:

    • CT scans demonstrated no or only subtle evidence of urinary extravasation in the initial patients.
    • Retrograde cystography revealed gross intraperitoneal extravasation in both patients, indicating missed diagnoses by CT.

  • These findings highlight potential limitations of CT in detecting bladder rupture.

    • Implications:

    • Retrograde cystography remains the gold standard for diagnosing bladder rupture.
    • CT may not be sufficiently sensitive as a standalone test for suspected bladder rupture.
    • Further research may be needed to optimize CT protocols or identify specific CT signs indicative of bladder injury.
