The purpose of this series was to evaluate the role of spectral Doppler and color flow Doppler sonography in the evaluation of partial testicular torsion.
Eight cases of partial testicular torsion, diagnosed on the basis of abnormal spectral Doppler waveforms or abnormal color flow Doppler findings, were retrospectively pooled from 2 teaching hospitals.
The age group ranged from 4 to 85 years. Testicles with partial testicular torsion showed variable spectral Doppler patterns, including increased, similar, or decreased amplitude of the arterial waveform relative to the contralateral testicle. Two cases showed reversal of arterial diastolic flow, and 1 case showed diastolic flow variability within the same testicle. Decreased blood flow was observed on color flow Doppler sonography in 7 of the 8 patients.
Variability of the Doppler waveform when compared with the contralateral testicle and reversal of diastolic blood flow are indirect clues that aid in the diagnosis of partial testicular torsion.
本系列研究的目的是评估频谱多普勒和彩色多普勒超声在评估睾丸部分扭转中的作用。
从2家教学医院回顾性收集8例经频谱多普勒波形异常或彩色多普勒检查结果异常诊断为睾丸部分扭转的病例。
年龄范围为4至85岁。睾丸部分扭转的睾丸表现出不同的频谱多普勒模式，包括相对于对侧睾丸动脉波形幅度增加、相似或降低。2例出现动脉舒张期血流逆转，1例在同一睾丸内出现舒张期血流变化。8例患者中有7例在彩色多普勒超声检查中观察到血流减少。
与对侧睾丸相比，多普勒波形的变化以及舒张期血流逆转是有助于诊断睾丸部分扭转的间接线索。
