超声造影对急性睾丸扭转的诊断价值

Diagnostic value of ultrasound imaging of acute testicular torsion

目的探讨超声造影(CEUS)技术对急性睾丸扭转的诊断价值。方法分析经手术证实的32例急性睾丸扭转患者的超声造影表现,研究超声造影对急性睾丸扭转的诊断价值。结果睾丸不完全扭转时的造影表现为睾丸实质内造影剂充填不均匀,可见斑片状高增强区及造影剂缺损区,睾丸内血流灌注减少。睾丸完全扭转造影表现为睾丸实质内始终未见造影剂进入。32例患者中,超声造影诊断睾丸完全扭转16例,不完全扭转14例,误诊及漏诊2例,诊断准确率为93.75%(30/32),与常规超声的诊断结果相比,更具有优势(P<0.05)。结论 CEUS有助于更准确地评价急性睾丸扭转内的血流信息,在急性睾丸扭转的诊断及鉴别诊断中具有很高的应用价值。

Objective To explore the significance of contrast-enhanced ultrasonography （CEUS） in the diagnosis of acute testicular torsion. Methods The ultrasonic imaging of 32 acute testicular torsion patients confirmed by surgery was retrospectively analyzed. Results The contrast performance of testicle which was not completely reversed was as follows：uneven filling of contrast agent in＇the testicular parenchyma, visible patchy enhancement region, defects of contrast agent, and reduced testicular perfusion. The imaging performance of testicle completely reversed was：no contrast agent within the testicular parenchyma. Of the 32 cases, 16 were diagnosed as complete reverse, 14 as incomplete reverse, and 2 were misdiagnosed by CEUS. The diagnostic accuracy was 93.75% （30/32）, with more advantages compared with conventional ultrasound diagnostic results by the chi-square test （P〈0.05）. Conclusion CEUS helps to more accurately evaluate the blood flow information inside the testis, which is of high applicative value in the diagnosis and differential diagnosis of acute testicular torsion.
