摘要
目的 应用彩色多普勒超声研究育龄期不育患者中精索静脉曲张(VC)伴有静脉血液反流对睾丸容积、睾丸内动脉峰值流速及阻力指数的影响.方法 将54例育龄期不育男性患者的108只睾丸,分为VC伴反流组(A组)、VC无反流组(B组)及无VC组(C组).采用二维超声精确测量每组睾丸径线并计算容积,用多普勒超声测量睾丸内动脉的峰值流速及阻力指数,并将所测结果进行比较.结果 A组的睾丸平均容积最小,与B、C组相比差异均有高度统计学意义(均P＜0.01)；而B组的睾丸容积与C组相比差异无统计学意义(P＞0.05).A、B、C三组间的睾丸内动脉峰值流速及阻力指数差异均无统计学意义(均P＞0.05).结论 在VC患者中,精索静脉血流反流会导致该侧睾丸容积缩小,但不会影响睾丸内动脉的峰值流速和阻力指数.
Abstract
Objective To study the affection of testicular volume, peak systolic velocity of intratesticular artery and resistance index in patients of varicocele associated with reflux by color Doppler ultrasound. Methods One hundred and eight testiculars in 54 infertile patients were divided into 3 groups. There was the case of varicocele associated with reflux (Group A) ,varicocele not associated with reflux (Group B) , and the case without varicocele ( Group C ). The size of testicular was measured accurately by two-dimensional ultrasound. Then the peak systolic velocity and the resistance index of intratesticular artery were measured by color Doppler ultrasound. The results were analyzed with statistical methods and comparison. Results The average testicular volume in Group A was smaller, which was significant differen in testicular volume compared with that in Group B or Group C (P<0.01). There was no significant difference in testicular volume between Group B and Group C (P >0.05). There was no significant differences in peak systolic velocity of intratesticular artery and resistance index in each group (P>0. 05). Conclusion Varcocele with reflux can reduce the size of ipsilateral testicular volume,but can not affect the peak systolic velocity of intratesticular artery and resistance index.
