目的比较经腹部超声和经阴道超声诊断多囊卵巢综合征的临床价值。方法将118例多囊卵巢综合征患者采用随机数字表法分为观察组和对照组各59例。观察组采用经阴道超声诊断,对照组采用经腹部超声诊断,比较2组诊断结果。结果 2组患者均可见两侧卵巢均匀性增大现象,外形均呈圆形或椭圆形,且图像边界清晰,包膜增厚,中间髓质成分及回声信号均增加。2组患者皮质内均可见不低于10个的小囊性结构,其中对照组超声特征为形态规则且无回声信号,而观察组则可见车轮状信号。观察组的卵巢面积增加、多囊性征象、髓质回声异常等的检出率均高于对照组(P<0.05),2组患者的卵巢体积比较差异无统计学意义(P>0.05)。观察组卵泡数量检出情况明显优于对照组(P<0.05)。结论对于多囊卵巢综合征患者行经阴道超声诊断的影像学特征检出率较高,临床价值显著,值得推广应用。
Objective To compare the clinical value of transabdominal ultrasound and transvaginal ultrasound in the diagnosis of polycystic ovary syndrome. Methods 118 patients with PCOS were divided into observation group and control group with 59 cases in each group by random number table. The observation group was diagnosed by transvaginal sonography and the control group by transabdominal ultrasound. The diagnostic results were compared between the two groups. Results The ovary uniformity on both sides was increased in both groups. The shape of the ovary was round or oval, the border of the image was clear, the capsule was thickened, the medullary composition and the echo signal were increased. There were no less than 10 small cystic structures in the cortex of the two groups, in which the control group had regular morphological features and no echo signals, while the observation group showed a wheel-shaped signal. The detection rate of ovarian area, polycystic signs and medullary echogenicity in observation group were higher than those in control group (P <0.05). There was no significant difference in ovarian volume between two groups (P> 0.05). The number of follicles in observation group was significantly higher than that in control group (P <0.05). Conclusions The detection rate of transvaginal ultrasonography in patients with PCOS is high, and its clinical value is significant. It is worth popularizing and applying.
