Value of Unenhanced Spiral CT in Patients With Flank Pain and Clinical Suspicion of Urolithiasis

Dr. Amol Gorakhnath Sasane, Brig. Dr. Hariqbal Singh

Abstract :

Unenhanced spiral CT was performed in 100 patients using dual slice spiral CT scanner with a slice thickness of 3 mm and a collimation of 2 mm. Patients of all age groups and both sexes presenting with flank pain were included. Out of 61 patients diagnosed as urolithiasis mean age of presentation was 41 years and predominantly males (70%) were affected. Secondary signs of obstruction were present in 80% of cases. These data yield a sensitivity of 100%, specificity of 96%, positive predictive value of 98% and negative predictive of 100% for determining the presence or absence of urolithiasis. The present study concludes that unenhanced spiral CT is sensitive as well as specific not only to diagnose urolithiasis but also to diagnose other causes that mimic urolithiasis in the genitourinary system or other systems.
