MR urography may provide an alternative to more conventional urinary tract imaging techniques. It does not require ionizing radiation or iodinated contrast material. When combined with furosemide and ureteral compression, MR urography provides fine detail and reflects function.

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.
