Preoperative urography in hypotensive patients with severe trauma

In hypotensive patients with severe trauma including renal injuries, the preoperative urogram is generally of poor quality. In many instances these patients are taken to the operating room with no films at all. We have proposed a protocol for the resuscitation of severely injured patients, following which we performed a carefully monitored high-dosage urogram. We demonstrated in 16 patients that diagnostic films can be obtained even in severely injured patients who were initially in shock.
