Purpose: To study the clinical application of low-dose unenhanced computed tomography with iterative reconstruction technique(LDCT-IR) on renal colic in the emergency department. Materials and Methods: We conducted a prospective, single-blinded, randomized, and non-inferiority study. From March 2014to August 2015, 112 patients with renal colic were included, and were randomized to either LDCT-IR (n=46) or standard-dose unenhancedCT (SDCT) (n=66) groups. The accuracy of urolithiasis diagnosis was the primary endpoint of this study. Radiationdose, size and location of the stone, hydronephrosis, other diseases except urolithiasis, and results of treatment were analyzedbetween the two groups. Results: The average effective dose radiation of SDCT was approximately four times higher than that of LDCT-IR (6.52 mSv vs. 1.63 mSv, p<0.001). There was no significant difference in the accuracy of ureteral stone diagnosis between the two groups (LDCTIRgroup: 96.97% vs. SDCT group: 98.96%, p=0.392). No significant difference was observed regarding the size and location of astone, hydronephrosis, and diagnosis of other diseases, except urolithiasis. False negative results were found in two LDCT-IR patientsand in one SDCT patient. In these patients, stones were misread as vascular calcification, and were difficult to diagnose becauseevidence of hydronephrosis and ureteral dilatation was not found. Conclusion: LDCT-IR, as a first-line imaging test, was non-inferior to SDCT with respect to diagnosis of ureter stones, and wasclinically available for the evaluation of renal colic.
