Abstract

A clinical observation was made with particular attention to radiologic diagnosis, complication and management on 69 patients of renal injury admitted to the Catholic Medical Center during the last 10 years. The results were as follows: 1. Minor renal injury was in 49 cases (71%), major renal injury in 19 cases (27.5%) and pedicle injury in 1 case (1.5%) according to Scott's classification. 2. IVU was performed in 68 cases for initial diagnostic study and 18 cases (31%) needed additional radiologic study for accurate staging. 3. CT was performed in 14 cases and its diagnostic accuracy was 93%. 4. Renal angiography was performed in 6 cases. Angioinfarction was performed in 1 case due to continuous bleeding and the other 5 cases showed localized parenchymal infarction or normal finding. 5. Sonography was performed in 6 cases for initial diagnostic study and in 3 cases for follow up study. 6. In major renal injury patients, the group which decided treatment after CT study revealed 16 7% of complication rate but the group which decided treatment without CT study revealed 38 5% of complication rate. 7. In major renal injury or pedicle injury patients, initial operative treatment group resulted in kidney loss in 70% of cases without complication but initial conservative treatment group resulted in kidney loss in 60% of cases and the delay of operation resulted in 70% of complication rate.From these results, CT is the choice of additional staging technique after initial IVU and initial surgical operation is adequate treatment procedure in major renal injury or pedicle injury patients.
