摘要：

目的 探讨睾丸扭转超声造影环状增强的机制。方法 18只雄性新西兰家兔随机分为对照组、鞘膜外扭转组及鞘膜内扭转组（n=6），后两组分别于鞘膜层内及鞘膜层外注入适量耦合剂制作成不同的模型，均用超声造影进行观察。结果 鞘膜外扭转组和鞘膜内扭转组均显示环状增强，而对照组无环状增强；鞘膜内扭转组环状增强明显强于鞘膜外扭转组；鞘膜内扭转组的鞘膜层环状增强明显强于阴囊皮肤肌肉层；鞘膜外扭转组阴囊皮肤肌肉层显示较弱环状增强，而鞘膜层未见增强。结论 睾丸扭转超声造影环状增强主要来源于睾丸鞘膜层，少量来源于阴囊皮肤肌肉层；环状增强的强弱有助于鉴别鞘膜内或鞘膜外睾丸扭转。

Abstract:

Objective To explore the mechanisms of ring-enhancement by contrast-enhanced ultrasound in testicular torsion. Methods Eighteen rabbits were randomly divided into control group, intravaginal testicular torsion group and extravaginal testicular torsion group (n=6). Appropriate amount of ultrasonic couplants were injected within or outside tunica vaginalis in intravaginal testicular torsion group and extravaginal testicular torsion group, and contrast-enhanced ultrasound was performed. Results Ring-enhancement was found in intravaginal testicular torsion group and extravaginal testicular torsion group, while no ring-enhancement was found in control group. Ring-enhancement in intravaginal testicular torsion group was significantly stronger than that in extravaginal testicular torsion group. In intravaginal testicular torsion group, tunica vaginalis was more strongly enhanced than scrotal sac and muscles. In extravaginal testicular torsion group, scrotal sac and muscles were slightly enhanced, while tunica vaginalis was not enhanced. Conclusion Ringenhancement by contrast-enhanced ultrasound in testicular torsion mainly comes from tunica vaginalis and partly from scrotal sac and muscles, and the extent of ring-enhancement may help in the differential diagnosis of intravaginal testicular torsion and extravaginal testicular torsion.
