We evaluated the clinical significance of arterial impedance as a predictor of testicular histology in adults with undescended (inguinal) testes.
We performed arterial impedance and testicular diameter measurements with the use of color Doppler ultrasonography on 22 adults with undescended testes. Arterial impedance of the contralateral descended testes served as controls. All patients later underwent inguinal orchiectomy and the testes were examined histologically.
Of the 22 undescended testes, 7 had arterial impedance values below 0.50, and the other 15 had values equal to or above 0.50. All testes with arterial impedance values below 0.50 had histologic scores between 2 and 3, whereas the others had scores of 3 and 8. Arterial impedance values and testicular volumes in the contralateral testes were significantly higher than the undescended testes. Although some of the testes with arterial impedance values above 0.50 had histologic score 3, testes with arterial impedance values below 0.50 never exceeded score 3. Volume differences of the undescended testes were not statistically significant.
Arterial impedance of an undescended testis may have a predictive value and provide more accurate information about its histology than the volume measurement itself.
我们评估了动脉阻抗作为成人隐睾（腹股沟型）睾丸组织学预测指标的临床意义。
我们对22例患有隐睾的成人使用彩色多普勒超声进行动脉阻抗和睾丸直径测量。以对侧下降睾丸的动脉阻抗作为对照。所有患者随后均接受腹股沟睾丸切除术，并对睾丸进行组织学检查。
在22个隐睾中，7个的动脉阻抗值低于0.50，另外15个的阻抗值等于或高于0.50。所有动脉阻抗值低于0.50的睾丸组织学评分在2至3分之间，而其他睾丸的评分为3至8分。对侧睾丸的动脉阻抗值和睾丸体积显著高于隐睾。尽管一些动脉阻抗值高于0.50的睾丸组织学评分为3分，但动脉阻抗值低于0.50的睾丸评分从未超过3分。隐睾的体积差异无统计学意义。
隐睾的动脉阻抗可能具有预测价值，并且比体积测量本身能提供有关其组织学的更准确信息。
