[Clinical analysis of renal trauma]

Since the start of the urological service in our hospital in 1986, we have experienced six male and one female patients with renal trauma. These cases were clinically analyzed and compared with hepatic trauma treated during the same period in our hospital. There were two cases of renal contusion, laceration and injury to the pedicle, and one of hemorrhage into the cyst in polycystic kidney. The causes of the trauma were mainly traffic accidents. Among them, 4 patients had injuries to other organs such as liver and brain and to the thorax. Two cases were able to retain both their kidneys, but the rest were treated with single nephrectomies. Six of the seven patients are alive. This proved that computerized tomography was very useful to decide the severity of injury, presence of lesions to other organs, and the treatment method. No close relation was observed between the time from injury to operation and the amount of blood transfusion. Moreover, hematological and biochemical analysis did not express the patient's status.
