A novel hysteroscopic hook for extracting retained contraceptive intrauterine devices under direct vision

Abstract

Objective The study evaluated the efficacy of removing retained intrauterine devices (IUDs) under direct vision using a novel hysteroscopic hook.

Methods In a retrospective observational study, 83 patients (group 1) underwent IUD extraction using a hysteroscopic IUD removal hook (HIRH) and 60 patients (group 2) underwent traditional hysteroscopic IUD extraction. We recorded the blood loss, operation time and success rate.

Results The operation time was shorter (10.7 vs. 17.7 min; p < 0.001) and the success rate higher in group 1 compared with group 2 (odds ratio 1.09; p = 0.027).

Conclusions The HIRH is an effective, simple, inexpensive and durable tool for the direct visual removal of IUDs partially embedded in the endometrium and for damaged IUDs.

方法 在一项回顾性观察研究中，83位患者（组1）采用宫腔镜下IUD取除钩（HIRH）取出IUD，60位患者（组2）采用传统宫腔镜IUD取出术。我们记录失血量、手术时间和成功率。

结果 组1和组2相比，手术时间缩短（10.7 比17.7; p＜0.001）,成功率提高（优势比 1.09； p = 0.027）。

结论 对于直视下取出部分植入子宫内膜的IUD和受损坏的IUD, HIRH是一种简单有效、花费少且耐用的工具。
