Current experience with computed tomographic cystography and blunt trauma.

Area of Science:

• Radiology
• Trauma Surgery
• Diagnostic Imaging

Background:

• Bladder rupture is a serious injury often resulting from blunt abdominal and pelvic trauma.
• Accurate and timely diagnosis is crucial for effective patient management and outcomes.
• Traditional diagnostic methods may have limitations in speed or accuracy.

Purpose of the Study:

• To evaluate the diagnostic efficacy of computed tomographic (CT) cystography for bladder rupture in blunt trauma.
• To compare the findings of CT cystography with results from operative exploration.
• To determine the sensitivity and specificity of CT cystography in diagnosing bladder rupture.

Main Methods:

• Retrospective review of blunt trauma patients diagnosed with bladder rupture between January 1992 and September 1998.
• Analysis of CT cystograms performed for blunt trauma evaluation during the same period.
• Comparison of CT cystography interpretations with operative findings in patients who underwent surgical exploration.

Main Results:

• 316 patients underwent CT cystography for blunt trauma evaluation; 44 were diagnosed with bladder rupture.
• CT cystography correctly identified bladder rupture in 42 of the 44 diagnosed patients (95% sensitivity).
• Operative findings matched CT cystogram interpretations in 82% of patients who underwent exploration; overall specificity was 100%.

Conclusions:

• CT cystography is an accurate and expedient method for diagnosing bladder rupture in blunt trauma patients.
• The diagnostic accuracy of CT cystography is comparable to traditional plain film cystography.
• CT cystography is recommended over plain film cystography for patients undergoing CT evaluation for trauma.
