彩色多普勒超声检测睾丸微石症合并精索静脉曲张患者睾丸动脉与精索静脉血流动力学的临床分析

Clinical Analysis of the Testicular Artery and Spermatic Vein Hemodynamics of Patients with Testicular Microlithiasis and Varicocele detected by Ultrasonography

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 detect the testicular artery and spermatic vein hemodynamics of patients with testicular microlithiasis （TM） complicated with varicocele （VC） by ultrasonography,and analyze the relationship between VC classification and TM typing.Methods：80 cases patients with TM complicated with varicocele VC and 80 cases of healthy male from August 2014 to Aug.ust 2016 were selected as the research group and the control group.The peak systolic velocity （PSV） and resistance index （RI） oftesticular artery and spermatic maximum velocity （VS-Vmax）,reflux time （TR）,spermatic vein diameter at rest （DR and diameter at Valsalva maneuver （DV） were detected.The relationship between TM classification and VC typing was analyzed by Spearman rank test.Results：There was no significant difference in the RI of testicular artery between two groups （P 〉0.05）,while the PSV of research group was significantly lower than that of the control group （P〈0.05）.The DR,DV,VS-Vmax,TR of research group were significantly higher than those of the control group （P〈0.05）.TM classification was positively correlated with the VC typing （P〈0.05）.Conclusions：The testicular artery and spermatic vein hemodynamics of TM combined with VC patients changed at different degrees,and VC severity was positively correlated with the number oftesticular micro stones.
