Abstract

Adequate radiographic demonstration of renal injury following blunt abdominal trauma is an important guide totherapy. The diagnostic evaluation of renal injuries usually begins with excretory urography, but not providedetailed information about the extent of injury. The need for a more accurate noninvasive modality led us toinvestigate the use of CT. We evaluated with CT and excretory urography 30 selected patients suspected of havingmajor renal injury. Of these patients 11 were also underwent arteriography for assessment of renal arterialinjuries. In this paper, we wish to analyze the result of the above modalites, particulary angiography and CT. Thebrief results were as follow. 1. Among 30 patients, 21 cases were male and 9 cases were female. About one third ofthese occured between the age of 20-29. 2. All cases were nonpenetrating blunt traumas. 3. Renal injuries werecategorized into 3 groups. Category I is minor renal injuries(14 cases), II is major renal injuries(1 cases), andIII is catastrophic renal injuries(3 cases). 4. IVP is the most common inital diagnostic modality and good forscreening of patients, but lack of specificity. In our study the specificity is about 33%. 5. CT is more accuratein detecting hematoma, parenchymal laceration, fracture and extravasation of urine, but agiography is moreconfirmative in diagnosis of vascular injuries. 6. Conservative management was done in 19 cases; 13 cases ofcategory I and 6 cases of II. Operation was performed in 11 cases: 1 case of category, I, 7 cases of II and 3cases of III. 7. Associated injuries were noted in 17 cases(57%).
