To assess the value of transvaginal color Doppler sonography in the differentiation of functional cysts from benign ovarian neoplasms in premenopausal women, 100 premenopausal women with the diagnosis of adnexal mass were enrolled in a prospective study. All patients underwent transvaginal color Doppler sonography during the follicular phase. We evaluated 107 masses. Tumor volume and morphology were assessed, as were tumor blood flow location, the number of vessels, the resistive and pulsatility indices, and the peak systolic velocity. Patients were followed up after 8 to 10 weeks by transvaginal sonography. Functional cysts were considered when spontaneous resolution occurred. Surgery was performed if a tumor enlarged or persisted after two scans. Thirty-nine (36.5%) cysts regressed spontaneously and 68 (63.5%) were removed surgically. Seven of the latter were follicular or luteal cysts and were considered to be functional cysts. No carcinoma was found. Arterial blood flow was detected in 28 (60.8%) functional cysts and in 42 (68.8%) benign neoplasms (P = 0.3446). The vessels were located peripherally in 27 (94.6%) functional cysts and in 37 (88.1%) benign neoplasms (P = 0.2226). No differences were found between functional cysts and benign neoplasms in mean resistive index (0.65, 95% confidence interval: 0.59 to 0.71 versus 0.64, 95% confidence interval: 0.60 to 0.69), mean pulsatility index (1.47, 95% confidence interval: 1.17 to 1.84 versus 1.57, 95% confidence interval: 1.26 to 1.86), number of vessels (1.1, 95% confidence interval: 0.7 to 1.3 versus 1.4, 95% confidence interval: 1.1 to 1.8), and peak systolic velocity (28.6 cm/s, 95% confidence interval: 24.7 to 34.2 versus 24.9 cm/s, 95% confidence interval: 21.6 to 28.3). We concluded that transvaginal color Doppler sonography is not useful to discriminate between functional ovarian cysts and benign ovarian neoplasms in premenopausal women.
为评估经阴道彩色多普勒超声在鉴别绝经前女性功能性囊肿与卵巢良性肿瘤中的价值，100例诊断为附件包块的绝经前女性纳入一项前瞻性研究。所有患者在卵泡期接受经阴道彩色多普勒超声检查。我们评估了107个包块。评估了肿瘤体积和形态，以及肿瘤血流位置、血管数量、阻力指数和搏动指数，还有收缩期峰值流速。患者在8至10周后通过经阴道超声进行随访。若包块自发消退则考虑为功能性囊肿。如果经过两次扫描后肿瘤增大或持续存在，则进行手术。39个（36.5%）囊肿自发消退，68个（63.5%）通过手术切除。其中7个为卵泡囊肿或黄体囊肿，被认为是功能性囊肿。未发现癌症。28个（60.8%）功能性囊肿和42个（68.8%）良性肿瘤检测到动脉血流（P = 0.3446）。27个（94.6%）功能性囊肿和37个（88.1%）良性肿瘤的血管位于周边（P = 0.2226）。功能性囊肿与良性肿瘤在平均阻力指数（0.65，95%置信区间：0.59至0.71对0.64，95%置信区间：0.60至0.69）、平均搏动指数（1.47，95%置信区间：1.17至1.84对1.57，95%置信区间：1.26至1.86）、血管数量（1.1，95%置信区间：0.7至1.3对1.4，95%置信区间：1.1至1.8）和收缩期峰值流速（28.6 cm/s，95%置信区间：24.7至34.2对24.9 cm/s，95%置信区间：21.6至28.3）方面未发现差异。我们得出结论，经阴道彩色多普勒超声对鉴别绝经前女性卵巢功能性囊肿和卵巢良性肿瘤并无帮助。
