灰阶血流成像对获得性梗阻性无精症患者睾丸血流灌注的评价

Evaluation of testicular blood perfusion in patients with acquired obstructive azoospermia using B-mode blood flow imaging

目的探讨灰阶血流成像(B-flow)评价获得性梗阻性无精症患者睾丸血流灌注的临床应用价值。方法使用B-flow和能量多普勒血流成像(PDI)技术观察71例获得性梗阻性无精症患者两侧睾丸的血流灌注情况,以PDI为标准评价B-flow观察获得性梗阻性无精症患者睾丸血流灌注的价值。结果 B-flow在睾丸最大切面检出血管数目:左侧(5.35±0.81)条,右侧(5.27±0.83)条;PDI在睾丸最大切面上检出血管数目:左侧(5.21±0.89)条,右侧(5.10±0.85)条,两者有较高相关性(r=0.82,P=0.00),差异无统计学意义。结论 B-flow对评价获得性梗阻性无精症患者睾丸的血流灌注有重要应用价值,可临床推广。

Objective To explore clinic application value of B-mode blood flow imaging（ B-flow ） in evaluating testicular blood perfusion in patients with acquired obstructive azoospermia.Methods Seventy-one patients with acquired obstructive azoospermia were examined for observing testicular blood perfusion by B-mode blood flow imaging and power Doppler flow imaging （PDI）.Using PDI as standards,the value of B-flow observaing testieular blood perfusion in patients with acquired obstructive azoospermia was evaluated.Results Testicular vascular number was detected by B-flow.There were （5.35±0.81） blood vessels on the left, and there were （5.27±0.83） blood vessels on the right.Testicular vascular number was detected by PDI. There were （5.21±0.89） blood vessels on the left, and there were （5.10±0.85） blood vessels on the right.There was a correlation between them （r =0.82,P=0.00）.There was no significant difference between them.Conclusion B-flow has an important application value in evaluating testicular blood perfusion in patients with acquired obstructive azoospermia.
