Intrauterine occlusion body (IUB). Preliminary report

The IUB or SOF-T is a further development of the IUD with additional functions and properties. In 368 IUB insertions over a period of 48 months, there was no intrauterine pregnancy. There was a low removal rate due to bleeding, pain, infection or partial expulsion in 277 insertions performed at two university centers over an average period of 8-1/2 cycles. In 80 cases tubal occlusion was directly or indirectly proven by different methods. The improved ultrasound localisation of the IUB is possibly responsible for its effectiveness and the soft ends are probably the main reason for its improved tolerance compared to other IUDs.
