A total of 61 cases of oholecystolithiasis and 64 cases of choledocholith were studied retrospectively. The sensitivity and positive predictive value of B-ultrasound and MRCP for cholelithiasis were evaluated. Results show that age, jaundice, and liver function had significant difference(P <0. 05 ). Age, DBIL and AKP had the highest correlation with choledocholith, the OR value being 1. 039 ,1. 102 and 1. 023 , respectively. The sensitivity of B ultrasound for cholecystolithiasis was 98. 4% , sensitivity was 64. 1% for choledocholithiasis, respectively. Sensitivity of MRCP for choledocholithiasis was 95. 3% . Function of gallbladder, especially elevated DBIL or AKP value may be helpful for the diagnosis of choledocholith.%回顾性分析61例胆囊结石及64例胆总管结石患者临床资料,并计算B超、磁共振胰胆管成像(MRCP)敏感度及阳性预测值.结果显示两组年龄、黄疸、肝功能指标差异有统计学意义 (P<0.05),其中年龄、直接胆红素(DBIL)、碱性磷酸酶(AKP)与胆总管结石相关性最大,OR值分别为1.039、1.102和1.023.B超对胆囊结石敏感度为98.4%,对胆总管结石敏感度为64.1%;MRCP对胆总管结石的敏感度为95.3%.
