| 目的 研究超声弹性成像(ultrasound elastography,UE)应变率比值(strain ratio,SR)评估精子密度正常范围的不同程度精索静脉曲张(varicocele,VC)患者睾丸硬度的价值。方法 设立病例组和正常对照组,病例组分为亚临床型VC、VCⅠ度、VCⅡ度、VCⅢ度。对病例组、对照组各50只睾丸进行UE检查并计算阴囊壁与睾丸之间的SR。对比分析病例组与对照组间、各组间SR的差异,分析精索静脉内径与SR、SR与精子密度之间的相关性。结果 病例组与对照组间、各组间两两比较SR差异均无统计学意义(P>0.05)。相关性分析显示,VC患者精索静脉内径与SR呈负相关(r=-0.459, P=0.001,P<0.05),SR与精子密度呈正相关(r=0.649,P=0.000,P<0.05)。随着精索静脉内径增加SR有降低趋势,精子密度有随SR降低而减少的趋势。结论SR可作为预测精子密度正常的VC患者随VC程度加重其睾丸硬度和睾丸生精功能变化趋势的参考指标。 |

| Abstract: |
| ABSTRACT Objective To research the value of ultrasound elastography strain ratio assess testicular stiffness in different degrees varicocele patients with normal range of sperm density.Methods Set up case group and contrast. Case group was divided into subclinical varicocele , gradeⅠof the varicocele, grade Ⅱ of the varicocele, grade III of the varicocele.The case group and contrast both have 50 testicles examine by ultrasound elastography and measure the strain ratio between testis’ around and testis’ middle . Comparative analyze strain ratio difference between the case group and the contrast, differences between the groups. Analyze correlation between spermatic vein diameter and strain ratio, strain ratio and sperm density. Results The strain ratio difference between the case group and the contrast, differences between the groups without statistical significance(P>0.05). Negative correlation between spermatic vein diameter and strain ratio（r=-0.459, P=0.001,P<0.05）,positive correlation between strain ratio and sperm density（r=0.649，P=0.000，P<0.05）. Conclusions Strain ratio can be used as a reference index of forecast testicular stiffness and testicular function trends, in varicocele patients with normal range of sperm density. |
