精索静脉曲张与前列腺静脉丛关系的彩色多普勒研究

目的 利用彩色多普勒超声(CDFI)评估精索静脉曲张(VC)与前列腺静脉丛之间的关系 ,以探讨VC的病因.方法用CDFI对左侧VC组(135例)、双侧VC组(51例)及对照组(100例)进行精索静脉、前列腺静脉丛内径(PVD )及血流动力学参数的观察 ,并对3组对象平静呼吸时 PVD、Valsalva试验时前列腺静脉丛最大反流速度(RFV )及平静呼吸时的最大流速(AFV)进行统计学分析.将两组VC患者的精索静脉内径(SVD)分别与PVD、RFV及AFV进行相关分析 ;并对其中30例VC患者术前术后PVD、RFV、AFV进行统计学分析.结果 双侧VC组PVD及RFV均明显大于对照组及左侧VC组(P＜0 .01);左侧VC组PVD、RFV与对照组比较 ,均差异无统计学意义(P＞0 .05).3组对象AFV比较 ,均差异无统计学意义(P＞0 .05).30例VC患者手术前、后PVD、RFV及AFV比较 ,均差异无统计学意义(P＞0 .05).结论 双侧 VC患者可能伴随有潜在的系统性血管异常.

Study on relationship between varicocele and prostatic venous plexus by color Doppler flow imaging

Objective To evaluate the relationship between varicocele (VC) and the prostativenouplexuby coloDoppleflow imaging(CDFI) and to explore the etiology of varicocele .MethodThe innediameterand the hemorrheologiparameterof spermativein and prostativenouplexuwere observed in 135 patientwith lefvaricocele(lefVgroup) ,51 patientwith bilat-eral V(bilateral Vgroup) and the control group(100 cases) by CDFI .The diameteof the prostativenouplexus(PVD) ,peak velocity of reflux flow (RFV) in the Valsalvtesand the peak velocity of antegrade flow (AFV) aresin 3 groupwere statistical-ly analyzed .ResultPVD and RFV in the bilateral Vgroup were greatethan those in the lefVgroup and the control group (P＜0 .01) .PVD and RFV in the lefVgroup had no statistical differencecompared with the control group (P＞0 .05) .AFV had no statistical difference among 3 group(P>0 .05) .PVD ,RFV and AFV in 30 caseof Vhad no statistical differencebe-tween before and afteoperation (P>0 .05) .Conclusion Bilateral Vmay be accompanied with potential systematic vascular abnormalities.
