Dilatation and curettage or hooking an occult intrauterine contraceptive device (IUD) may fail to recover the device on occasion. Theoretically, endoscopic observation should enable the controlled removal of this type of device. Of 200 patients who underwent hysteroscopic examination, 10 had an occult IUD. In 8 cases, the device was visible through the hysteroscope, and in 6 patients a successful removal was accomplished with this endoscopic technic. Failures and problems are discussed, and the importance of adequate preoperative study is stressed. Hysteroscopy is an effective procedure in the recovery of the occult intrauterine contraceptive device in selected nonpregnant patients.
扩张刮宫术或钩取隐匿性宫内节育器（IUD）有时可能无法取出该装置。从理论上讲，内镜观察应该能够控制取出这类装置。在接受宫腔镜检查的200例患者中，有10例存在隐匿性IUD。在8例中，通过宫腔镜可以看到该装置，并且在6例患者中，通过这种内镜技术成功取出。文中讨论了失败情况和问题，并强调了充分术前检查的重要性。宫腔镜检查对于特定非妊娠患者隐匿性宫内节育器的取出是一种有效的方法。
