The probability of doing abortion surgery need to clear the uterus is relatively small, abortion surgery is carried out in the early stages of pregnancy, the gestational sac is relatively small, the vast majority of the surgical process can be done once clean. As long as you choose a more formal and professional organization, the doctor’s operating technology is also very mature, the vast majority of patients do not need to carry out the purging surgery. Only a small number of incomplete abortion, bleeding and residuals in the uterine cavity after the abortion, need to consider the removal of the uterus surgery. Most of the patients are related to the inflammation of the pelvis, because the presence of inflammation leads to a tighter adhesion of the gestational sac to the uterine wall, and therefore also increases the probability of residual embryos. If the uterus needs to be cleared after surgery, medications to promote uterine recovery need to be continued after the procedure, as well as preventing infection.
