睾丸微石症与精索静脉曲张的超声表现及相关性研究

Study on the Ultrasonography and the Correlation Between Testicular Microlithiasis and Varicocele

目的探讨睾丸微石症(Testicular Microlithiasis,TM)与精索静脉曲张(Varicocele,VC)的超声表现及相关性。方法回顾性分析了TM合并VC患者的109例声像图,根据TM声像图分为经典型睾丸微石症(Classic Testicular Microlithiasis,CTM)和限制型睾丸微石症(Limited Testicular Microlithiasis,LTM),其中CTM组35例,LTM组74例。将VC声像图分为亚临床静脉曲张(Subclinical Varicocele,SVC)组20例、VCⅠ组45例、VCⅡ组24例及VCⅢ组20例。应用超声检查分别测量患者右侧VC和左侧VC的Valsalva试验的最大内径(DV),分析TM分型与VC分级相关性。结果左右两侧VC的DV分别为(0.27±0.06)、(0.22±0.05)cm,两组比较差异有统计学意义(t=-6.141,P=0.000);TM分型与VC分级的相关性分析差异无统计学意义(χ2=3.225,P=0.532;r=-0.01,P=0.916);CTM组、LTM组的左侧VC和右侧VC的DV比较组间比较差异有统计学意义(F=12.375,P=0.000);CTM组中左侧和右侧VC的DV比较差异有统计学意义(P=0.005),LTM组中左侧和右侧VC的DV比较差异有统计学意义(P=0.000)。结论TM合并VC患者的左侧VC的DV明显较右侧DV增宽,且不能认为TM和VC两者之间有明确相关性。

Objective This paper aimed to explore ultrasonic manifestation and the correlation between testicular microlithiasis (TM) and variclcele (VC). Methods Retrospectively analyzed sonogram of 109 patients with TM and VC, and divided into the classic testicular microlithiasis (CTM) and limit testicular microlithiasis (LTM) according to the sonogram of the TM, CTM group 35 cases, LTM group 74 examples. The VC sonogram was divided into subclinical varices (SVC) group 20 cases, VC Ⅰ group 45 cases, VC Ⅱ 24 cases and VC Ⅲ group 20 cases. Application of the ultrasound measured the left and right VC Valsalva test the largest diameter (DV), to analyze the correlation between TM parting with VC grading. Results The DV of the right VC was (0.22±0.05) cm, and of the left VC is (0.22±0.05) cm. There were no significant statistical difference between the two groups (t=-6.141, P=0.000); there was no significant statistical difference between TM parting with VC grading (χ2=3.225, P=0.532; r=-0.01, P=0.916); TM (CTM group, LTM group) and VC (left and right sides of VC) of the DV had a significant difference (F=12.375, P=0.000); the DV of VC between the right and left comparison was significantly different in CTM and LTM (P=0.005). Conclusion The DV of left side in patients with TM and VC was significantly larger than that of right side, and there was no clear correlation between TM and VC.
