Comparison of the Clinical Value of Ultrasonography and Radiography in the Diagnosis of Ureterolithiasis

Objective:To study the diagnostic value of ultrasonography and radiography for ureterolithyiasis. Methods: From 2004.10 to 2005.10,120 patients with ureterolithiasis were examined by ultrasonography and radiography.There were unilateral ureterolith in 196 patients and bilateral ureterolith in 4 patients.Two patients were proved by surgery,11 patients were proved by ureterorenoscopy,in 107 patients the ureterolith was expelled.The ultrasonographic diagnosis was compared with that of radiography including abdominal plain film (KUB) and intravenous pyelography (IVP).Results: 92.7% of the ureteroliths were detected by ultrasonography,the accuracy of detectability was higher than that of KUB and IVP (62%).Furthermore,ultrasonography provided more direct information of the urinary system and their associated abnormalities which could not be revealed by radiography.Conclusion:Ultrasonography is the method of first choice of imaging investigation for ureterolithiasis.
