OBJECTIVE. The standard of care for the diagnosis and follow-up of urolithiasis is unenhanced CT. The hypothesis of this study was that that by using image fusion of subsequent ultrasound (US) with the initial unenhanced CT, ureteral stones can be precisely localized. CONCLUSION. Of the 25 stones founds on unenhanced CT studies, 22 (88%) were confidently identified using US–unenhanced CT fusion within 72 hours after the initial CT scan was obtained. US–unenhanced CT fusion might obviate the need for repeated CT scans for monitoring urolithiasis.
