| 目的 探讨高频彩超检查不育症患者精索静脉曲张(VC)的价值及VC对生育力的影响。方法 检测32例正常人及116例不育症患者的精索静脉及睾丸,记录精索静脉在平静呼吸时最大内径(DR)及Valsalva试验时的最大内径(DV)、最大返流速度(Vmax)及返流持续时间(TR),测量并计算睾丸体积。每位受检者取精液送检,重点观察精子密度和活动率。[HTH]结果 ①各VC组与对照组DR、DV、Vmax、TR比较及组间两两比较的差别均具有显著性意义(P<0.01)。②各VC组左侧睾丸体积小于对照组(P<0.01)。VC Ⅲ级组右侧睾丸体积小于对照组(P<0.05)。③各VC组精子密度低于对照组(P<0.05,P<0.01),精子活动率低于对照组(P<0.01),各VC组之间两两比较精子活动率差别均有统计学意义(P<0.05)。[HTH]结论 高频超声可为男性不育精索静脉曲张患者提供精确的精索静脉内径、血流动力学参数及睾丸大小等客观指标,有助于男性不育症病因的筛选及对生育力的评价。 |

| Objective To investigate the value of high frequency ultrasound in examing male infertility with varicocele, and discuss the effect of varicocele on fertility. Methods Thirty-two healthy male volunteers (contral group)and 116 infertile men (infertility group) with left varicocele were examined. All the patients were divided into four subgroups. Internal spermatic vein diameter (DR) and testis volume were observed in a normal way. Such signs as internal spermatic vein diameter (DV), the peak velocity of reflux (Vmax) and reflux time (TR) were detected in Valsalva-test. Spermatozoid density and activity were tested. Results ①DR, DV, Vmax and TR among the four, subgroups and contral group were statistically significant (P<0.01). The differences among four subgroups were statistically significant each other (P<0.01). Left testis volume of four subgroups was smaller than that of the control group (P<0.01). Difference of spermatozoid density between all the four subgroups and contral group was statistically significant (P<0.05,P<0.01). Difference of spermatozoid activity between all the four subgroups and control group was statistically significant (P<0.01). There were significant differences of spermatozoid activity among four subgroups each other (P<0.05).Conclusion There was significant positive correlation between severity of varicocele and intemal spematic vein diameter, the peak velocity of reflux and reflux time respectively. Varicocele can cause testis volume and spermatozoid density and activity to decrease. High frequency ultrasound can provide the accurate internal spematic vein diameter, hemodynamics and the testis volume for observing male infertility caused by varicocele. It helps to screen the reason and to assess the fertility of male infertility. |
