| 【】 目的：通过实时剪切波弹性成像技术(SWE)对睾丸硬度的测量,探讨该项技术在男性少弱精症患者中的临床应用价值。方法：取睾丸正常且无泌尿系疾病的健康志愿者500例,同时选取诊断为少弱精症患者118例,将少弱精症患者分为3组：轻度少弱精症33例,中度少弱精症35例,重度少弱精症及无精症50例,利用SWE技术对所有研究对象进行测量并比较各组弹性模量值。结果：轻、中度少弱精症患者与志愿者弹性模量值比较,差异无统计学意义(p>0.05)；重度少弱精症患者与志愿者弹性模量值的最大值及平均值比较,差异有统计学意义(p<0.05),当睾丸弹性模量值最大值为4.25kpa时,ROC曲线下面积最大为0.88,其灵敏度和特异度分别为79%、76%。结论：SWE技术可以准确地评价睾丸组织的硬度及均匀程度,为临床研究少弱精症患者提供依据。 |

| Abstract: |
| Objective To evaluate the clinical application of real-time shear wave elasticity imaging (SWE) in the measurement of testicular hardness in male patients with oligospermia. Methods 118 patients with oligospermia were enrolled in this study. Five hundred healthy volunteers with normal testis and without urinary diseases were selected. while oligozoospermia patients were divided into three groups: 33 cases of mild oligozoospermia, 35 cases of moderate oligozoospermia, 50 cases of mild oligospermia and azoospermia. All the people were measured with SWE technology and compare the values of elastic modulus of each group. Results There was no significant difference in the elastic modulus between the patients with mild and moderate oligospermia and the healthy volunteers (p> 0.05). There was significant difference in the maximum and mean values of the elastic modulus values of the patients with severe oligospermia and the healthy volunteers (p <0.05). When testicular elastic modulus maximum value of 4.25 kpa, the area under the ROC (receiver operating characteristic)curve up to 0.88, the sensitivity and specific degrees were 79%, 76%. Conclusion The SWE technique can accurately evaluate the hardness and uniformity of testicular tissue, and Sprovide the basis for the clinical study of oligospermia patients. |
