本文测量、研究了296例带不锈钢圆单环妇女的宫腔X线造影,多数为带环10年以上的多产妇.研究结果认为,宫腔与环的大小比例合适,位置在宫腔的上部,是长期避孕有效的重要因素.多产妇以安外径2.2cm环为主,0～1产妇以安外径2.0cm环为主.宫腔中横径是选环的主要指标.自然脱落和带器受孕是宫内节育器避孕失败的主要原因.惰性宫内节育器是否有效与机械作用有关.为了从形态学的角度研究不锈钢圆单环长期有效的因素,我所于1978年夏到1982年冬,在有关单位的支持下;作了带环妇女宫腔造影.主要对象为带环10年以上,平均产次4产者.现将296例带环宫腔造影的观测,研究结果报告于下,并用部分未带环宫腔造形作为对照.
In this paper, the study of 296 cases of women with a single round stainless steel uterine X-ray images, most of the more than 10 years with a ring of polygamy.Results that the appropriate ratio of the size of the uterine cavity and the ring, located in the upper part of the uterine cavity , Is an important factor in the effective long-term contraception.Multiple women to the outer diameter of 2.2cm ring-based, 0-1 maternal to safety outer diameter of 2.0cm ring.The intrauterine diameter of the ring is the main indicator of the ring.Natural shedding and IUD is the main reason for contraceptive failure of IUD.Inertic IUD is effective and mechanical effects.In order to study the long-term effective factors of stainless steel circular single-ring from the morphological point of view, I was in the summer of 1978 to 1982 Winter, with the support of the relevant units; made with a ring of women’s uterine cavity imaging. The main object for more than 10 years with a ring, the average yield of 4 births now 296 cases with ring uterine contrast observation, the results reported In the next, and with some not with the uterine shape as a control.
