目的:采用彩色多普勒超声检测睾丸微石症(TM)合并精索静脉曲张(VC)患者睾丸动脉与精索静脉血流动力学的情况,并分析VC分级与TM分型的关系。方法:选择2014年8月到2016年8月80例TM合并VC患者及80例健康男性分别作为研究组与对照组,均采用彩色多普勒超声检测睾丸动脉收缩期峰值血液速度(PSV)、阻力指数(RI)及精索静脉最高流速(VS-Vmax)、静脉返流时间(TR)、平静呼吸最大内径(DR)、Valsalva试验最大内径(DV)。用Spearman秩相关分析TM分类与VC评分的关系。结果:两组睾丸动脉RI比较无显著差异(P>0.05)。研究组PSV明显小于对照组(P<0.05),精索静脉DR、DV、VS-Vmax、TR均显著大于对照组(P<0.05)。TM分类与VC分级呈正相关(P<0.05)。结论:TM合并VC患者睾丸动脉、精索静脉血流动力学均存在不同程度的改变,VC严重程度与睾丸微小结石数量呈正相关。
Objective: To investigate the hemodynamics of testis and varicocele in patients with testicular microlithiasis (TM) and varicocele (VC) by color Doppler sonography. The relationship between VC classification and TM typing was analyzed. Methods: Eighty patients with TM combined with VC and 80 healthy men from August 2014 to August 2016 were selected as the study group and the control group, and the peak systolic blood velocity (PSV) of the testicular artery was measured by color Doppler sonography. Resistance index (RI), VS-Vmax, TR, DR and Valsalva’s maximum diameter (DV). Spearman rank correlation analysis TM classification and VC score relationship. Results: There was no significant difference between two groups (P> 0.05). The PSV in the study group was significantly lower than that in the control group (P <0.05). The levels of DR, DV, VS-Vmax and TR in the varicocele were significantly higher than those in the control group (P <0.05). TM classification was positively correlated with VC grade (P <0.05). Conclusion: The hemodynamics of testis and spermatic vein in patients with TM complicated with VC have varying degrees of change. The severity of VC has a positive correlation with the number of testicular microlithiasis.
