Gray-scale ultrasonography in the evaluation of renal trauma

Static and real-time gray-scale ultrasound examinations were performed on seven patients who had minor, major, and catastrophic renal trauma. The sonographic findings in avulsion of the renal pedicle, fractured kidney, ruptured renal cyst, perinephric and subcapsular hematomas, and pelvic blood clots are presented. Ultrasonography provided a valuable adjunct to conventional urography and radionuclide studies by adding information on the extent of renal and retroperitoneal injury.
