Abstract

PURPOSE: To evaluated the effectiveness of abdominal ultrasonography as the initial diagnostic method in blunt renal trauma.
MATERIALS AND METHODS
This study was undertaken to compare computerized tomography with abdominal ultrasonography in radiographic staging of blunt renal trauma(Renal Injury scale grade I-V by Moor) except vascular injury. During 3-years period(May 1994 to March 1997), emergency computerized tomography was performed in 66 patients with blunt renal trauma, simultaneously 34 patients among 66 patient were scanned by abdominal ultrasonography.
RESULTS
Gross hematuria were present 48% of renal trauma cases. The degree of hematuria showed not correlation with the severity of renal injury(p-value=0.213, by Chi-square test). In diagnostic agreement of abdominal ultrasonography compared to computerized tomography, the diagnostic agreement of minor renal injury(x=0.544, by k2 statistics) was higher than that of major renal injury(r=0.375, by k2 statistics). The overall diagnostic agreement of abdominal ultrasonography in detecting adjacent organ injury was 0.321 (k value).
CONCLUSIONS
In ultrasonography imaging, we concluded that minor blunt rectal trauma is not necessary other radiologic evaluation, but major blunt renal trauma should be evaluated by computerized tomography for proper diagnosis of combined injury and diagnostic staging of renal trauma. Renal trauma associated Intraabdominal injury should undergo with ultrasonography-guided paracentesis. Based under result of our study, we suggest the use of abdominal ultrasonography as the initial diagnostic method in blunt renal trauma compatible for prompt diagnosis and treatment.
