Computerized tomographic staging of renal trauma: 85 consecutive cases.
The Journal of Urology
|September 1, 1986
Summary
Computerized tomography (CT) offers superior staging for renal trauma compared to excretory urography and angiography. CT accurately identifies injuries, aiding in diagnosis and management of blunt and penetrating renal trauma.
Area of Science:
- Radiology
- Trauma Surgery
- Urology
Background:
- Renal trauma diagnosis relies on imaging, but accuracy varies.
- Traditional methods like excretory urography and angiography have limitations in staging severity.
Purpose of the Study:
- To compare the diagnostic accuracy of computerized tomography (CT) against excretory urography and angiography for renal trauma.
- To evaluate CT's effectiveness in staging blunt and penetrating renal injuries.
Main Methods:
- Retrospective analysis of 85 patients with renal trauma.
- Comparison of CT findings with excretory urography, angiography, and surgical outcomes.
- Assessment of perirenal hematoma, intrarenal hematoma, and parenchymal disruption on CT.
Main Results:
- CT identified perirenal hematoma (29.4%), intrarenal hematoma (24.7%), and parenchymal disruption (17.6%) as common findings.
- Excretory urography showed poor correlation with injury severity.
- Angiography understaged injuries in 1 of 5 cases; CT depicted all angiographic findings.
Conclusions:
- Computerized tomographic staging is more sensitive and specific for renal trauma than other modalities.
- CT is recommended for suspected multiple injuries, indeterminate excretory urography, or significant clinical trauma.
