阴道超声监测卵泡生长及排卵的临床意义

The clinical significance of observing growth of the follicle and ovulation by transvaginal sonography

目的 观察阴道超声监测卵泡发育及排卵在不孕症中的作用。方法 对 6 9例 15 7周期不孕症患者采用阴道超声监测卵泡发育及排卵。自月经第 8天开始 ,每 2天监测 1次 ,当卵泡直径大于 15mm时 ,每天监测 1次 ,直至排卵 ;如仍未排卵 ,则改为 2～ 3d测 1次 ,直至下次月经来潮。结果 排卵的85个周期中 ,最大卵泡平均值为 2 3.4mm ,平均增长率为 2 .42mm d ,消失在周期的 13～ 16d ;排卵延缓期8例 32个周期 ,卵泡最大平均值出现在月经第 2 4～ 39天 ,最大直径为 2 4.1mm ,排卵在月经第 2 6～ 42天 ;无卵泡发育的 9例 14个周期 ;无优势卵泡的 5例 18个周期 ;8例因服用克罗米芬或hCG出现卵巢过度刺激综合征。结论 阴道超声监测卵泡发育直观性好 ,对于准确测定排卵时间、指导受孕起着非常重要的作用 ,是治疗不孕症不可缺少的重要手段。

Objective To observe the effect of observing growth of the follicle and ovulation by transvaginal sonography for patients with infertility.Methods The transvaginal sonography was applied to observe growth of the follicle and ovulation for 69 patients with infertility of 157 menstrual cycles.To observe one time every 2 days from the 8th day of the menstrual cycle,observe one time everyday,after the follicle's diameter>15 mm,until ovulation.If there was still no ovulation,then observe one time every 2～3 days until next menstrual cycle.Results In the 85 menstrual cycles that have ovulated,the average diameter of the biggest follicles was 23.4 mm,the average increasing rate was 2.42 mm/d,they disappeared in the 13th～16th days of the menstrual cycles,In the 32 cycles of the 8 cases of delayed ovulation period,the biggest follicles appeared in the 24th～39th days of the cycles,their average diameter was 24.1 mm,they ovulated in the 26th～42th days of the cycles.There were 14 cycles of 9 cases that have no follicle's growth.18 cycles of 5 cases that have no dominance follicle.8 cases appeared overian hyperstimulation syndrome because of oral clomiphene or hCG.Conclusion Observing follicle's growth by transvaginal sonography was clear.Which plays an important role in detecting the time of ovulation accurately and guiding fertilized.It is a important way to cure infertility.
