目的探讨超声在女性中枢性性早熟中的诊断价值。方法选择2012年12月至2014年10月期间在江门市新会妇幼保健院接受治疗的中枢性性早熟患者100例,分析超声诊断特点并与100例非性早熟女童进行对比分析。同时通过促性腺激素释放激素激发试验结果检测超声诊断的准确性。结果中枢性性早熟患者子宫容积、宫体/宫颈比例、卵巢容积及直径大于4cm卵泡数均大于非性早熟女童,对比差异有统计学意义(χ2=1.52,P<0.05)。超声诊断的准确率为83%。结论超声诊断能有效鉴别中枢性性早熟与正常女童,其准确率较高,操作简便安全,无创伤性,且患儿容易接受,具有较高的诊断价值,适用于中枢性性早熟的初步诊断。
Objective To investigate the diagnostic value of ultrasound in female precocious puberty. Methods 100 cases of central precocious puberty patients who were treated in Xinhui Maternal and Child Health Hospital of Jiangmen City from December 2012 to October 2014 were selected. The characteristics of ultrasonic diagnosis were analyzed and compared with 100 non-precocious precocious girls. At the same time, the diagnostic accuracy of ultrasound was tested by gonadotropin-releasing hormone provocation test. Results Among the patients with central precocious puberty, the volume of uterus, the ratio of uterus / cervix, the volume of ovary and the number of follicles more than 4cm in diameter were significantly higher than those of non - precocious precocious puberty patients. The difference was statistically significant (χ2 = 1.52, P <0.05). The diagnostic accuracy of ultrasound was 83%. Conclusion Ultrasound diagnosis can effectively differentiate central precocious puberty and normal girls with high accuracy, simple and safe operation, noninvasiveness and easy acceptance in children, which is of high diagnostic value and suitable for the preliminary diagnosis of central precocious puberty .
