The effects of unilateral testicular torsion on the blood flow of the contralateral testis were investigated. Fourteen adult male dogs were recruited. Seven dogs underwent unilateral testicular torsion of 4 h duration, and the other seven dogs had a control operation. Testicular blood flow was determined by colour Doppler ultrasonography before and after the testicular torsion. Bilateral orchidectomy was performed at the end of the study and histopathological changes were evaluated. Values of peak systolic velocity, end diastolic velocity, and resistive index were not statistically significant between ipsilateral and contralateral testes in the study group (p > 0.05). On comparison with the control group, blood flow in the contralateral testes showed no statistically significant difference (p > 0.05). Oedema and congestion were seen on ipsilateral testes in the study group. No histopathological changes were noted on the contralateral testes. Minimal oedema and congestion secondary to manipulation were found in the control operation testes. We conclude that unilateral testicular torsion does not decrease contralateral testicular blood flow as shown by colour Doppler ultrasonography.
研究了单侧睾丸扭转对侧睾丸血流的影响。招募了14只成年雄性犬。7只犬接受了持续4小时的单侧睾丸扭转，另外7只犬进行了对照手术。在睾丸扭转前后通过彩色多普勒超声测定睾丸血流。在研究结束时进行双侧睾丸切除术，并评估组织病理学变化。研究组同侧和对侧睾丸的收缩期峰值流速、舒张末期流速和阻力指数值无统计学意义（p>0.05）。与对照组相比，对侧睾丸的血流无统计学显著差异（p>0.05）。研究组同侧睾丸可见水肿和充血。对侧睾丸未发现组织病理学变化。在对照手术睾丸中发现因操作引起的轻微水肿和充血。我们得出结论，如彩色多普勒超声所示，单侧睾丸扭转不会降低对侧睾丸的血流。
