title: Spontaneous urinary extravasation: detection rate with 64-row multidetector computed tomography in patients presenting with acute abdomen.
abstract: The aim of this study was to detect the rate of spontaneous urinary extravasation (SUE) with computed tomography (CT) in patients presenting with acute abdomen. Seven hundred thirteen abdominal CT examinations with i.v. contrast media requested mainly from the emergency department and urology clinics for sudden onset abdominal pain, flank pain, nonspecific abdominal pain with nausea and vomiting, and renal colic between September 2007 and August 2011 were retrospectively reviewed. Only adult patients were included in the study. Three patients with SUE were detected. One had a mid-ureteral stone while the etiology for the other two patients was unknown. Two of the patients were treated conservatively; one was treated with stenting with a double-j catheter. SUE should be considered in the differential diagnosis of patients presenting with acute abdomen and perinephric-periureteral fluid collection inconsistent with stone size and who are occasionally stone free. Early and precise diagnosis of SUE plays an important role in the management protocol of patients presenting with acute abdomen.
