彩超观察女孩性早熟子宫、卵巢及卵巢动脉血流与性激素的关系

Girls with Precocious Puberty:Volume of Uterus and Ovary and Relationship Between the Ovarian Arterial Blood Flow and the Sexual Hormone Levels

目的探讨正常女孩和性早熟女孩子宫、卵巢形态及卵巢动脉血流与性激素变化的关系。方法采用彩色多普勒血流影像技术测子宫、卵巢大小及卵泡直径和检测血清中性激素水平。结果（１）随青春成熟度的增加，性激素水平提高，卵泡直径与个数增加，子宫容积大于２ｍｌ，卵巢容积大于１．５ｍｌ，卵泡直径大于６ｍｍ，卵泡个数大于３，则提示青春期发动。（２）特发性性早熟与正常青春发育相比，性器官发育不成熟。（３）性早熟各期卵巢动脉血流呈高阻力型。结论彩色多普勒超声是检查女孩性早熟简易可靠的方法。

bjective To inquire into the changes in morphology of uterus and ovary and relationship between the ovarian arterial blood flow and the sexual hormone levels in normal girls and those with precocious puberty.Method The technique of color Doppler blood flow imaging was used and the sexual hormone levels were detected.Results The sexual hormone levels rose and the follicles increased in diameter and number with puberscence stages.The uterum exceeding 2 ml in volum,the ovary exceeding 1.5 ml in volum,the follicle with a diameter of more than 6 mm,and the presence of 3 or more follicles indicated puberal starting .The development of sexual organs in girls with idiopathic precocious puberty was less than that in normal girls.The ovarian arterial blood flow in various stages of precocious puberty showed a high impedance.Conclusion Color Doppler flow imaging is reliable for diagnosing precocious puberty.
