目的探讨经阴道超声在排卵障碍性不孕症治疗中对药物诱导卵泡发育与排卵监测的临床价值。方法应用经阴道超声对30例药物诱导排卵的不孕症患者进行监测,观察卵泡的数量、大小、形态、内部回声变化,并与对照组资料作比较。结果药物诱导排卵和自然排卵周期中卵泡生长发育的超声表现相似。药物诱导排卵平均优势卵泡的数目、排卵前24 h卵泡平均直径、妊娠率均高于对照组(P<0.05)。结论在药物诱导排卵中,经阴道超声能直接观察卵泡生长发育情况,确定卵泡的位置、形态、数目,较准确判断排卵日期,对指导临床用药,减少药物所致并发症的发生具有十分重要的意义。
Objective To investigate the clinical value of transvaginal ultrasound in the monitoring of drug-induced follicular development and ovulation in the treatment of ovulatory dysplasia. Methods 30 cases of infertility induced by drugs were monitored by transvaginal sonography. The number, size, shape and internal echo of ovarian follicles were observed and compared with the control group. Results Drug-induced ovulation and natural ovulation cycle follicular growth and development of ultrasound similar performance. The number of follicles with drug-induced ovulation average superiority, the average follicle diameter and pregnancy rate at 24 h before ovulation were all higher than those in control group (P <0.05). Conclusion In the process of drug-induced ovulation, the transvaginal ultrasound can directly observe the growth and development of follicles, determine the position, shape and number of follicles and determine the ovulation date accurately. It is very important to guide the clinical medication and reduce the occurrence of drug-induced complications significance.
