diabetic mellitus, hypertension, and other chronic diseases. this article updates the medical field in terms of the benefits and limitations of telemedicine when dealing with poor-prognosis sonographic results. Korea could update their telemedicine system in the obstetric field based on this article. Korean government covers almost all costs related to diseases, but low-cost procedures and legal problems are privately handled between doctors and patients or between hospitals and patients. thus, Korean physicians generally oppose telemedicine. In addition to overall low costs, the Korean system does not pay fees for counseling services, with the exception of some special cases such as neuropsychological counseling. Due to these limitations, some companies in Korea have created telemedicine applications on smartphones [2]. however, physicians do not want to be involved in this situation. We read that telemedicine is well established in rural areas of Japan [3]. Japanese doctors are willing to engage in telemedicine because doctors were closely connected before becoming involved in telemedicine. telemedicine is likely to become a worldwide trend. Some countries, such as the USA, have accepted telemedicine because of the disadvantages of high costs and geographical distances associated with traditional medicine. Other countries, including Japan, have also adopted telemedicine because of geographical distances. Other countries are working on catching up with the technical trends in the field of telemedicine. With scientific developments, telemedicine is expected to further develop and become a necessary part of the medical field. this article is helpful in its discussion of establishing telemedicine in other countries, including Korea, which aims to establish telemedicine in every field, including obstetrics.
