目的研究卵泡发育成熟度及子宫内膜变化于与不孕症关系,为临床治疗不孕症等疾病提供有效影像学资料。方法应用经阴道超声技术对56例不孕妇女的168个月经周期的卵泡发育情况及子宫内膜厚度、类型进行了观察并进行统计学分析。结果 56例患者的168个月经周期,各排卵类型按超声图像表现56例各排卵类型可分6类:正常排卵型21例;无优势卵泡形成型26例;无卵泡发育型2例;排卵延缓型3例;黄素化卵泡不破裂型(LUFS)3例;多囊卵巢1例(经临床确诊)。内膜厚度与卵泡增长呈正比,排卵前,子宫内膜厚度<7mm时,妊娠率低;三线型子宫内膜妊娠率高于均质型子宫内膜。对照组与不孕症组卵泡直径及内膜厚度比较,两组间比较均有统计学意义(P<0.05)。结论经阴道超声是一种有价值的监测卵泡生长发育及子宫内膜变化的手段,对指导临床诊治不孕症及合理用药具有重要意义
Objective To study the relationship between the maturation of follicular development and endometrial changes and infertility and to provide effective imaging information for clinical treatment of infertility and other diseases. Methods Transvaginal ultrasonography was used to observe the follicular development and the thickness and type of endometrium of 168 menstrual cycles in 56 infertile women and to make statistical analysis. Results 56 cases of 168 menstrual cycles, each ovulation type according to ultrasound images 56 cases of each ovulation type can be divided into 6 categories: normal ovulation type 21 cases; no dominant follicular formation type 26 cases; follicular development type 2 cases; ovulation delayed Type 3 cases; luteinized follicles without rupture (LUFS) in 3 cases; 1 case of polycystic ovary (clinically confirmed). Intima thickness and follicular growth is proportional to ovulation, uterine endometrial thickness <7mm, the pregnancy rate is low; three-line type of endometrial pregnancy rate is higher than that of homogeneous endometrium. Control group and infertility follicular diameter and intima thickness compared between the two groups were statistically significant (P <0.05). Conclusion Transvaginal ultrasonography is a valuable means of monitoring follicular growth and endometrial changes, which is of great significance in guiding clinical diagnosis and treatment of infertility and rational drug use
