[Clinical analysis of 35 patients with renal injury]

Because of the increase of abdominal trauma owing to traffic accident, the number of renal injury is increasing. Between May 1, 1986 and December 31, 1989, thirty-five cases with renal injury were treated in our hospital. The cases were classified as contusion, minor laceration, major laceration and vascular injury by the clinical findings and the radiographic evaluation. Contusion had 22 patients, who were treated conservatively except one with preexisting hydronephrosis. Four patients of minor laceration were all treated conservatively. In four cases of major laceration nephrectomy was performed, the other five cases were healed conservatively. There were two death cases caused by other organ injuries. The extent of associated injuries influenced the prognosis, rather than the degree of renal damage. Thirty-three cases except two survived with no complication. In cases of major injury same were managed conservatively, other required surgical treatment. Sometimes it is difficult to determine which treatment should be done. Indication for surgical treatment is discussed.
