宫内节育器异位调查

Survey of intrauterine device dislocation

目的:调查不同环型、不同植入时间的宫内节育器(intrauterine device,IUD)的异位情况。方法:妇女健康普查中询问植入IUD环型和时间,并行B超检查。分析4816例不同环型组间IUD的异位率以及各组内不同植入时间段间IUD的异位率。结果:O型、T型、Υ型、元宫型,以及其它环型组间的IUD发生率的差异具有统计学意义,O型IUD的异位率高于其它型;各组不同植入时间段间的IUD发生率的差异无统计学意义。结论:环型选择不当是IUD异位的危险因素之一,而植入时间并不影响IUD异位的发生率。

Objectives：To investigate incidence rate of dislocation of different shaped intrauterine device（IUD）and different implantation duration.Methods：To enquire the shape of implanted IUD and the duration of implantation of 4816 cases in female health screening,then B-scan was performed to examine the location of IUD.The incidence rate of dislocation of different shaped IUD and of different implantation duration of the same shaped IUD was analyzed.Results：The incidence rate of dislocation of O-shaped IUD was significantly higher than T-shaped,Υ-shaped,Yuangong-shaped,and other or unknown shaped IUD.There was no significant difference of incidence rate of dislocation among different implantation duration of each same shaped IUD.Conclusions：Inadequate shape rather than implantation duration is one of risk factors of IUD dislocation.
