PURPOSE
To evaluate power Doppler ultrasonography to predict sperm recovery in azoospermic patients.
METHODS
Color Doppler and power Doppler ultrasonography of testis were performed in 38 patients before testicular sperm extraction. Analysis of blood flow included the pulsatility and resistance index of intratesticular vessels and testicular artery, and power Doppler of testis. The results of power Doppler of testis were classified into three categories: 0, no vessels found; 1, one to three vessels; 2, more than three vessels found.
RESULTS
Power Doppler of both testis showed a significant difference between obstructive azoospermia and non-obstructive azoospermia (Fisher's exact test - P = 0.02), and between the groups with and without sperm recovery (Fisher's exact test - P = 0.001). Doppler indices of intratesticular vessels and testicular artery were similar between the groups.
CONCLUSIONS
Testicular Power Doppler assessment showed that patients with obstructive azoospermia have better blood flow than patients with non-obstructive azoospermia, and power Doppler is able to predict sperm recovery in azoospermic patients.
目的
评估能量多普勒超声预测无精子症患者精子恢复情况的能力。
方法
对38例患者在进行睾丸精子提取术前进行睾丸的彩色多普勒和能量多普勒超声检查。血流分析包括睾丸内血管和睾丸动脉的搏动指数和阻力指数，以及睾丸的能量多普勒。睾丸能量多普勒的结果分为三类：0类，未发现血管；1类，发现一至三条血管；2类，发现三条以上血管。
结果
在梗阻性无精子症和非梗阻性无精子症之间（Fisher精确检验 - P = 0.02），以及在有精子恢复和无精子恢复的组之间（Fisher精确检验 - P = 0.001），双侧睾丸的能量多普勒均显示出显著差异。睾丸内血管和睾丸动脉的多普勒指数在各组之间相似。
结论
睾丸能量多普勒评估显示，梗阻性无精子症患者的血流情况优于非梗阻性无精子症患者，且能量多普勒能够预测无精子症患者的精子恢复情况。
