摘要
目的:探讨超声造影(CEUS)在急性实验性睾丸不全扭转诊断中的应用价值。方法:健康杂种犬8只,随机选择一侧精索扭转,做成7只睾丸不全扭转动物模型及1只睾丸完全扭转动物模型。以扭转侧作为病例组,以健侧作为对照组,于扭转前、扭转后即刻和/或6 h行超声造影检查,并进行时间-强度曲线(TICs)分析。结果:未扭转前两侧睾丸造影剂开始出现、达峰时间几乎一致,峰值强度及曲线下面积基本相同;不全扭转病例组睾丸表现为造影剂延迟灌注,造影剂开始出现、达峰时间较对侧延长,峰值强度及曲线下面积降低(P<0.05);完全扭转睾丸表现为睾丸内始终无造影剂灌注。结论:CEUS在急性睾丸不全扭转诊断中具有很高的应用价值。
Objective:To explore the application value of contrast-enhanced ultrasonography(CEUS) in the diagnosis of acute experimental incomplete testicular torsion.Methods:Seven incomplete and 1 complete testicular torsion models were established in 8 healthy hybrid dogs by twisting unilateral spermatic cord.The twisted testes were included in the model group and the healthy ones in the control.All the dogs underwent CEUS before,immediately after,and/or 6 hours after the torsion,followed by time-intensity curve analysis.Results:The arriving time(AT) and the time to peak(TTP) of the contrast agents in the bilateral testes were almost coincident,and the peak intensity(PI) and the area under the curve(AUC) in the bilateral testes basically the same before the torsion.The incompletely torsioned testes showed delayed perfusion of contrast agents,prolonged AT and TTP,and decreased PI and AUC as compared with the contralateral testes(P 0.05),while the completely torsioned one exhibited no perfusion all the time.Conclusion:CEUS has a very high application value in the diagnosis of acute incomplete testicular torsion.
