OBJECTIVE The purpose of our study was to determine the value of secondary signs of ureteral obstruction on helical unenhanced CT. MATERIALS AND METHODS Over a 19-month interval, 312 patients with acute flank pain were imaged with helical unenhanced CT. Ureteral stone disease was confirmed to be present in 109 patients and confirmed to be absent in 111 patients Ninety-two remaining patients had no confirmatory imaging studies or surgery and were unable to be contacted for follow-up.
