Uterine perforation in patients wearing the Copper-T and the Copper-7 intrauterine contraceptive devices has been studied. In Bollnäs, Sweden, three perforations occurred in 1 156 insertions of the Copper-7, and in New York, USA, six perforations occurred in 1 153 insertions of the Copper-T. Cervical perforation seems to be a special feature of the Copper-T, while the Copper-7 tends to perforate through the uterine wall. The perforations can be divided into "primary" perforations, related to the insertion procedure, and "secondary" perforations, caused by uterine contractions. The diagnosis and treatment of uterine perforations by intrauterine devices is discussed.
对佩戴铜 - T型和铜 - 7型宫内节育器的患者发生子宫穿孔的情况进行了研究。在瑞典的博尔奈斯，1156例铜 - 7型宫内节育器植入中有3例发生穿孔；在美国纽约，1153例铜 - T型宫内节育器植入中有6例发生穿孔。宫颈穿孔似乎是铜 - T型宫内节育器的一个特点，而铜 - 7型宫内节育器则倾向于穿透子宫壁。穿孔可分为与放置操作相关的“原发性”穿孔和由子宫收缩引起的“继发性”穿孔。文中讨论了宫内节育器所致子宫穿孔的诊断和治疗。
