title: A comparative study of intravenous urograms and radionuclide renal scans in diagnosis of renal trauma.
abstract: We analyzed 31 patients who underwent intravenous urograms (IVU) and radionuclide renal scans (RNRS) in the investigation of blunt abdominal trauma, and compared the IVU to the RNRS in the definition of blunt renal injuries, and their correlation with patients' symptoms and signs. Thirteen patients had abnormal IVU and 12 had abnormal RNRS (42% of the 31 patients). In 8 patients findings on IVU correlated with those on RNRS (62%), and in 5 patients findings were different (38%). Only 2 patients (6.5%) had significant differences which may have influenced further treatment. Only 1 patient required operative management. Follow-up IVUs were performed on 6 of the 13 patients who had abnormal radiologic studies. The radionuclide renal scan was shown to be as accurate as the intravenous urogram in defining renal trauma. Patients who undergo liver-spleen scans for investigation of blunt abdominal trauma, and who may have renal trauma, may well undergo RNRS at the same time and obviate the need for an IVU, without any diagnostic compromise.
