目的比较睾丸扭转复位后的常规超声与超声造影声像特点。方法 7例单侧睾丸扭转患者行手术复位6例,手法复位1例,复位后行常规超声及超声造影检查。结果复位后患侧睾丸常规超声声像与健侧睾丸比较无明显特异改变;超声造影显示,5例造影剂充盈良好,睾丸周边可见环形增强,造影剂均较均匀进入睾丸实质,2例出现造影剂局部或整体不充盈。结论超声造影在显示睾丸扭转复位后血流的恢复及恢复程度上较常规超声敏感,有助于判断复位术后睾丸的存活能力。
Objective To compare the characteristics of conventional ultrasound and contrast-enhanced ultrasound after torsion-reduction. Methods Seven patients with unilateral testicular torsion underwent surgical resection in 6 cases and manual reduction in 1 case. After reduction, conventional ultrasound and contrast-enhanced ultrasound were performed. Results Compared with contralateral testes, the results of conventional ultrasound imaging of ipsilateral testis showed no obvious changes. Ultrasound imaging showed that the contrast media filled well in 5 cases, and the circumferences of testis showed annular enhancement. Contrast media were more uniform in testicular parenchyma and contrast media in 2 cases Partial or overall unfilled. Conclusion Contrast-enhanced ultrasound is more sensitive than conventional ultrasound in showing the degree of recovery and recovery of blood flow after testicular torsion reduction. It is helpful to determine the testicular viability after reduction.
