VTQ技术在精索静脉曲张不育患者睾丸容积、组织硬度及精液质量中的应用价值

Application value of VTQ technique in the volume and tissue hardness of testicle, and semen quality in infertility man with varicocele

目的:探讨声触诊组织量化(VTQ)技术在精索静脉曲张(VC)不育患者中的应用价值。方法:2016年11月-2019年11月本院收治的VC不育患者120例(病例组),同期行体检且超声和精液检查正常男性为对照组。检测两组精子浓度和活力,测定睾丸体积及横向剪切波速度(SWV)值,分析SWV值与精液质量和睾丸体积的相关性。结果:病例组患者精子浓度和活力小于对照组,左侧睾丸体积小于右侧和对照组,精索静脉曲张程度越重精子浓度、活力和左侧睾丸体积越小,左侧睾丸SWV值低于对照组(均P<0.05);SWV值与精子浓度、活力、睾丸体积呈正相关(P<0.05)。结论:VTQ技术测定睾丸SWV值可能成为评估VC不育患者睾丸容积、组织硬度及精液质量的间接指标。

Objective: To investigate the application value of virtual touch quantification(VTQ) technique for evaluating infertility of man with varicocele. Methods: 120 infertile men with varicocele were selected in study group from November 2016 to November 2019, and the normal men with normal ultrasound and semen who wanted physical examination were selected in control group during the same time. The sperm concentration and motility, testicular volume, and transverse shear wave velocity(SWV) of men in the two groups were measured. The correlation of SWV value with semen quality and testicular volume was analyzed. Results: The sperm concentration and motility of men in the study group were significant lower than those of men in the control group. The volume of left testis of men in the study group was significant smaller than that of their right testis and the men in the control group(P<0.05). The sperm concentratio of men with worse varicocele was significant less, their motility of sperm was significant lower, and their left testicular volume was significant smaller(P<0.05). The SWV value of left testis of the men in the study group was significant lower than that of men in the control group(P<0.05). SWV value was positively correlated with the sperm concentration, motility and testicular volume(P<0.05). Conclusion: The testicular SWV measured by VTQ may be an indirect index for evaluating the volume and tissue hardness of testicular, and semen quality of infertility men with varicocele.
