摘　　要：目的探讨常规超声(CUS)和超声造影(CEUS)在兔急性闭合性阴囊(BST)损伤中的诊断价值。方法用健康新西兰雄性大白兔建立挫伤、血肿、破裂3种类型的睾丸损伤模型。于造模前、造模后即刻、2、4 h和6 h对睾丸行常规、造影超声检查,分析2种超声检查方法诊断BST的价值。结果(1)CEUS对挫伤、血肿及破裂的不同时间点诊断的灵敏度、特异度和准确度均高于CUS;(2)CUS诊断挫伤的敏感度随时间延长减低;(3)CEUS诊断睾丸挫伤、血肿ROC曲线下面积(A)均大于CUS,差异有统计学意义(Z=2.356,2.091,P均<0.05)。CEUS诊断睾丸破裂ROC曲线下面积(A)大于CUS,差异无统计学意义(Z=0.192,P>0.05)。结论 CEUS可提高BST的诊断准确度,能够成为BST检查的一个重要补充。Objective To evaluate the value of conventional ultrasonography （CUS） and contrast-enhanced ultrasonography（CEUS） in the diagnosis of blunt testicular trauma in rabbits. Methods Three different types of blunt testicular trauma, including contusion, hematoma and rupture were made by healthy male New Zealand white rabbits. We examined all the rabbits＂ scrotums before hitting and immediately after hitting, 2 hours, 4 hours and 6 hours after hitting though CUS and CEUS. And then Assessed the accuracy of CUS and CEUS in the diagnosis of blunt testicular trauma. Results （1）The sensitivity, specificity and accuracy of the diagnosis by CEUS are higher than that by CUS in different time point. （2）The sensitivity of diagnosing contusion by CUS gradually reduced. （3）The area of testicular contusion and hematoma under ROC curve by CEUS was larger than that by CUS, which showed statistical significance （Z=2. 356, 2. 091, all P〈0.05）. The area of rupture under ROC curve by CEUS was larger than that by CUS, which showed no statistical significance （Z=0. 192, P〉0.05）. Conclusions The accuracy was significantly improved in diagnosing blunt testicular trauma by CEUS. CEUS can be used as an important complement of CUS.
