目的应用三维成像技术指导放置宫内节育器,对其临床效果进行评价研究。方法对2006年1-6月间来指导中心要求置器者随机分为两组,分别应用三维超声成像技术和二维B超检查后指导放置宫内节育器。随访6-12个月统计各种原因的停用数,评价两组的有效性、续用率、副反应发生率、可接受性等。结果试验组与对照组一年累积妊娠率无显著差异(P>0.05),脱落率和因症取出率有显著差异(P<0.05),两组节育器的累积续用率方面,试验组的92.29%明显高于对照组的72.96%。结论应用三维超声成像技术指导放置宫内节育器可显著减轻副反应发生率,提高节育器的续用率,具有很高的临床推广价值。
Objective To apply three-dimensional imaging technique to guide the placement of IUD and evaluate its clinical effect. Methods From January to June 2006 to the guidance center to ask for placement were randomly divided into two groups, respectively, the application of three-dimensional ultrasound imaging and two-dimensional B-ultrasound after the guide to place the IUD. All patients were followed up for 6-12 months to count the number of discontinuation for various reasons, and the effectiveness, follow-up rate, incidence of side effects and acceptability of the two groups were evaluated. Results There was no significant difference in one-year cumulative pregnancy rate between the experimental group and the control group (P> 0.05), and there was a significant difference between the rate of exfoliation and the removal rate (P <0.05). In the two groups, 92.29% was significantly higher than 72.96% of the control group. Conclusion The application of three-dimensional ultrasound imaging to guide the placement of IUD can significantly reduce the incidence of side effects and improve the IUD success rate, which has a high clinical value.
