A 41-year-old male patient presented to the Emergency Department (ED) of Sultan Qaboos University Hospital (SQUH) complaining of left flank pain of one day's duration which was colicky and increasing in intensity. There was no history of fever, nausea or vomiting or other significant medical history; however, a similar episode had occurred previously. The patient's vital signs were stable and he was afebrile. Physical examination of the abdomen was non-contributory; routine microscopic urinalysis was normal. In view of the suspicion of left renal colic, he was referred for a non-contrast enhanced computed tomography (NCCT) scan, the gold standard at SQUH to assess urinary tract calculi in patients presenting with renal colic.
