Our aim was to gain an idea about testicular injury by comparing the reduced volume, which is one of the indirect indicators of testicular damage in undescended testes, and by evaluating the reduced microvascular blood flow by superb microvascular imaging, and also to determine whether superb microvascular imaging modes could detect microvascular blood flow in more detail in the decreased volume of undescended testes.
We compared testicular blood flow in undescended testes via conventional Doppler imaging, color superb microvascular imaging, and monochrome superb microvascular imaging techniques with contralateral normally located testis and normal control group. Each sample of testicular tissue was evaluated using a qualitative method. Spot color encoding and linear flow color encoding counts determined in testicular parenchyma were counted separately and expressed as numerical data. The localization of the examined testes in the grayscale was noted (proximal inguinal canal, medial inguinal canal, distal inguinal canal, and scrotal). The volume of undescended testes was calculated automatically via a formula for volume.
Monochrome superb microvascular imaging is significantly superior in visualizing the vascularity of undescended testes compared with color Doppler, power Doppler and color superb microvascular imaging ( = 0.001). Also, undescended testes have a significantly lower blood flow compared with contralateral normal testes ( = 0.001). The volume of undescended testes was significantly lower than the contralateral normal testes.
The volume, structure and blood flow are indirect signs of testicular damage in undescended testes. Monochrome superb microvascular imaging can detect vascularity in undescended testes better than the conventional Doppler imaging technique and color superb microvascular imaging. Based on our findings, we can report that monochrome superb microvascular imaging can be used to evaluate testicular injury and vascularity of undescended testes.
我们的目的是通过比较睾丸体积减小（这是隐睾中睾丸损伤的间接指标之一），并通过超声微血管成像评估微血管血流减少情况，来了解睾丸损伤，同时确定超声微血管成像模式是否能更详细地检测隐睾体积减小情况下的微血管血流。
我们通过传统多普勒成像、彩色超声微血管成像和单色超声微血管成像技术，将隐睾的睾丸血流与对侧正常位置的睾丸及正常对照组进行比较。每个睾丸组织样本采用定性方法进行评估。分别计算睾丸实质中确定的点状颜色编码和线性血流颜色编码数量，并以数值数据表示。记录检查的睾丸在灰度图像中的位置（腹股沟管近端、腹股沟管内侧、腹股沟管远端和阴囊）。通过体积公式自动计算隐睾的体积。
与彩色多普勒、能量多普勒和彩色超声微血管成像相比，单色超声微血管成像在显示隐睾血管方面明显更具优势（P = 0.001）。此外，隐睾的血流明显低于对侧正常睾丸（P = 0.001）。隐睾的体积明显低于对侧正常睾丸。
体积、结构和血流是隐睾中睾丸损伤的间接征象。单色超声微血管成像在检测隐睾血管方面比传统多普勒成像技术和彩色超声微血管成像更好。基于我们的研究结果，我们可以报告单色超声微血管成像可用于评估隐睾的睾丸损伤和血管情况。
