A comparative study has been realized to test the accuracy of oral cholecystography versus real time ultrasonography in 150 patients with gallbladder lithiasis surgery. Oral cholecystography correctly diagnosed 107 cases (70%), whereas ultrasonography diagnosed gallbladder lithiasis in 145 or in 96,5% of the cases. Failure of the technique in the remaining cases was related to a scleroatrophic gall bladder with stones of less than 3 mm. These results confirm that ultrasonography must be proposed as the first examination for the diagnosis of gallstones.
一项对比研究对150例接受胆囊结石手术的患者进行了口服胆囊造影术与实时超声检查准确性的测试。口服胆囊造影术正确诊断出107例（70%），而超声检查诊断出胆囊结石145例，占病例数的96.5%。其余病例中该技术的失败与伴有小于3毫米结石的硬化萎缩性胆囊有关。这些结果证实，超声检查必须作为诊断胆结石的首选检查方法。
