After medical abortion According to the 2006 WHO Frequently asked clinical questions about medical abortion, the presence of remaining<unk>  in the uterus (as detected by obstetric ultrasonography) after a medical abortion is not an indication for surgical intervention (that is, vacuum aspiration or dilation and curettage). Remaining<unk>  will be expelled during subsequent vaginal bleeding. Still, surgical intervention may be carried out on the woman's request, if the bleeding is heavy or prolonged, or causes anemia, or if there is evidence of endometritis. In delayed miscarriage In delayed miscarriage (also called missed abortion), the Royal Women's Hospital recommendations of management depend on the findings in ultrasonography: *Gestational sac greater than 30-35mm, embryo larger than ~25mm (corresponding to 9+0 weeks of gestational age): Surgery is recommended. It poses a high risk of pain and bleeding with passage of<unk> . Alternative methods may still be considered. * Gestational sac 15-35mm, embryo smaller than 25mm (corresponding to between 7 and 9+0 weeks of gestational age): Medication is recommended. Surgery or expectant management may be considered. * Gestational sac smaller than 15-20mm, corresponding to a gestational age of less than 7 weeks: Expectant management or medication is preferable. The<unk>  may be difficult to find surgically with a considerable risk of failed surgical procedure. In incomplete miscarriage In incomplete miscarriage, the Royal Women's Hospital recommendations of management depend on the findings in ultrasonography: * Retained<unk>  smaller than 15mm: Expectant management is generally preferable. There is a high chance of spontaneous expulsion. * Retained<unk>  measuring between 15 and 20mm: Medical or expectant management are recommended. Surgery should only be considered upon specific indication. * At retained<unk>  measuring over 35 to 50mm, the following measures are recommended: :*Administration of misoprostol to hasten passage of<unk> . :*Admission to inpatient care for observation for a few hours or overnight until the majority of the<unk>  has passed and bleeding subsided. :*After apparent failure of misoprostol, a gynecologic examination should be done prior to considering surgical evacuation of the uterus or the patient leaving the
