Seong Ku Woo
To determine the diagnostic value of ultrasound in patient with clinically suspected ureteral calculi, a prospective study was performed on 58 patients. Of these, 42 patients had 44 ureteral calculi and 16 patients had no calculi. The sonograhic of a distal shadowign highly echogenic reflector along the ureter, with or without dilatation of the proximal ureter. Ultrasound correctly diagnosed 42 stones among 44 calculi and there was one false positive examination. The overall diagnostic accuracy was 95% Ultrasonography appears to be a very useful adjunct for the diagnosis of ureteral calculi when excretory urography is equivocal or contraindicated. Also ultrasonography was valuable in monitoring passage of radiolucent ureteral stones.
