IUD is the process of removing the residual tissue from the uterine cavity with the use of instruments. IUD can be performed under ultrasound monitoring, so that on one hand, the uterus can be cleared as much as possible at one time, avoiding re-cleaning the uterus. On the other hand, it can also prevent perforation of the uterus, which can cause serious consequences. If the uterine cavity can be clearly seen during the procedure, it means that the uterus has not been perforated, and the operation has gone smoothly. Meconjugation is suitable for incomplete abortion, retained abortion, pregnancy within 12 weeks, gravidity, etc. The specific need to combine with their own condition to the hospital to request a professional physician to judge. Therefore, if you can see a clear line of the uterine cavity when you undergo the evacuation, it proves that the operation went well. Avoid coitus for 1 month after the operation and check the uterus regularly after the operation.
