摘　　要：目的探讨实时剪切波弹性成像(SWE)技术在急性睾丸扭转中的临床应用价值。方法选取40例睾丸扭转坏死组、28例睾丸扭转术后复活组及60例健康对照组作为研究对象,测量并比较健康对照组、睾丸扭转坏死组及复活组术前、术后1个月、3个月睾丸弹性模量值以及睾丸大小的测量。结果睾丸扭转复活组术前、术后1个月与对照组睾丸弹性模量值比较,差异有统计学意义(P<0.05);睾丸扭转复活组术后3个月与对照组睾丸弹性模量值比较,差异无统计学意义(P>0.05);当睾丸弹性模量值最大值为7.85kpa时,ROC曲线下面积最大为0.88,其灵敏度和特异度分别为82%、78%,另外,坏死组睾丸体积明显大于复活组及对照组,差异有统计学意义(P<0.05)。结论 SWE技术可以较为准确地评价睾丸组织的硬度,结合睾丸大小在一定程度上能判断睾丸扭转程度和病情发展,为临床治疗方法的选择提供可靠依据,也可作为术后睾丸功能恢复的评价依据。Objective To study the clinical application value of real-time shear wave elastography （SWE） technology in assessing the prognosis of acute testicular torsion fixation.Methods In this work, we selected 40 cases of testicular torsion as a necrosis group, 28 cases of testicular torsion as a resurrection group, and 60 cases of healthy individuals as a control group, and then, measured and compared the testicular elastic modulus value and testicular size of subjects in the three groups before the pre-operation and 1 month, 3 months after the operation correspondingly.Results The testicular elastic modulus values of subjects in resurrection group before the operation and 1 month after the operation were significantly different compared to those in the control group （ P 〈0.05）. However, the testicular elastic modulus values of subjects in resurrection group 3 month after the operation had no statistically significant difference compared to those in the control group （ P 〉0.05）. When testicular elastic modulus maximum value was set up as 7.85 kpa, the area under the receiver operating characteristic （ROC） curve was up to 0.88, the sensitivity and specific degrees were 82%, 78%. In addition, the testicular volume of subjects in necrosis group was significantly greater than those in the resurrection group and the control group and the difference was statistically significant （ P 〈0.05）.Conclusion SWE technology can more accurately evaluate the hardness of testicular tissue. In combination with testicular size, this technology can judge, to a certain extent, the degree of testicular torsion and the development of the disease, which provides reliable basis for the selection of clinical treatment method. Also, such a technology can be used for the evaluation of postoperative testicular function recovery.
