Non-contrast renal CT scan findings: a retrospective review

ABSTRACT

To evaluate the findings of unenhanced Non-contrast Renal Computed Tomography in patients with flank pain. One hundred-seventy eight seven patients with flank pain were referred for unenhanced renal computed tomography at Prince Ali Hospital between November 2008 to February 2009. The original films of each patient were reviewed and the presence of urinary tract calculi was recorded. other urinary abnormalities were also noted. Out of 178 study population, 73 patients [41%] were reported as normal, 59 patients [33%] having hydronephrosis. The stone was located in the upper third of the ureter in 27 patients [45.8%]. Thirteen patients on the right side and 10 on the left. 12.4% were found to have various renal abnormalities. Unenhanced Renal Computed Tomography is an accurate investigation for determining the presence or abscence of urinary tract calculi in patients complaining of flank pain. It identifies renal and uretric stones; location and size. Other causes of flank pain can also be identified
