The paper summarizes the author's ten-year experience with 1446 interval insertions of the MLCu250 standard-type device, and makes comparison between the first two-year results of this and the MLCu375 IUD. The 120th month was completed by 106 MLCu250 users, and the cumulative woman-months of use (wmu) were 78,078. At the end of the second year, 976 patients were at risk in this group, representing a total of 28,097 wmu. From the initial 224 MLCu375 IUD cases, 160 (2,151 wmu) and 93 (3634 wmu) were eligible for life-table calculation at the end of the first and the second year, respectively. The overall performance was evaluated by net and gross cumulative and yearly specific rates as suggested by Tietze. These figures are detailed by the article. Based on this evaluation, two statements are made: (1) the MLCu250 standard-type device has a good overall performance and a longer life span than was previously expected; (2) the first two-year results with the MLCu375 are more favorable (lower termination rates, higher continuation) than the MLCu250.
本文总结了作者对1446例MLCu250标准型宫内节育器进行间隔放置的十年经验，并比较了其与MLCu375宫内节育器的前两年使用结果。106例MLCu250使用者完成了120个月的随访，累积使用妇女月数（wmu）为78078。在第二年结束时，该组有976例患者处于风险期，共计28097个妇女月。从最初的224例MLCu375宫内节育器病例中，分别有160例（2151个妇女月）和93例（3634个妇女月）在第一年末和第二年末符合生命表计算条件。按照蒂策建议的净累积率、总累积率和年度特定率对总体性能进行了评估。本文详细列出了这些数据。基于此评估，得出两点结论：（1）MLCu250标准型宫内节育器总体性能良好，使用寿命比之前预期的更长；（2）MLCu375宫内节育器的前两年使用结果比MLCu250更理想（终止率更低，续用率更高）。
