Obstetrics and Gynecology

The Department of Obstetrics and Gynecology provides medical care for all phases of a woman’s life from puberty to pregnancy, child birth, and menopause, with a main focus on reproduction. The department supports a wide range of research. The findings are translated to clinical application for improved diagnosis and treatment.

Medical services

The department provides general and specialized outpatient care. Inpatients are treated by a supervising physician and his/ her team.

Diagnosis and treatment policy

A treatment plan is determined not only based on discussion among attending
physicians but also through regular case review meetings with all staff physicians. Joint review meetings with the Departments of Pediatrics and Pediatric Surgery and other departments are also held regularly to provide comprehensive interdisciplinary management of mothers and children.

Specialties

Comprehensive management of care for mothers and children is provided in cooperation with the Departments of Pediatrics and Pediatric Surgery by making extensive use of ultrasound diagnosis in fetuses. Abnormal pregnancies and deliveries are also handled. An emphasis is also placed on treating patients with infertility (habitual abortion) and on reproduction-related problems in all phases of a woman’s life, including in vitro fertilization and other infertility treatments, adolescent amenorrhea, and postmenopausal osteoporosis.

Target diseases

Normal and abnormal pregnancy and delivery, genetic counseling, endocrine abnormality, infertility, adolescent amenorrhea, infertility (habitual abortion), menopause-associated diseases, postmenopausal osteoporosis

Advanced treatments/ Specialized treatments

In vitro fertilization and embryo transfer (IVF-ET)

In-vitro fertilization is performed in about 200 patients annually. Of these, about 120 patients undergo ICSI (intra-cytoplasmic sperm injection), direct injection of a sperm into an egg. Fresh embryo transfer, a procedure in which an early embryo immediately after in-vitro fertilization is placed back into the uterus, is performed in about 70 patients annually. Frozen-thawed embryo transfer is also performed in about 250 patients annually. With the help of these procedures, about 50 babies are born each year. In Addition, we positively investigate the cause of recurrent implantation failure.

Treatment of infertility and habitual abortion

Since many factors are associated with habitual abortion, an appropriate treatment plan is developed after careful assessment of the cause. Patients with antiphospholipid antibody syndrome and those with thrombotic tendencies due to a decrease in anticoagulation factors are treated with prednisolone, aspirin and heparin. Favorable results have been achieved in treating patients with these procedures.

Frequently performed tests

  • Ultrasound diagnosis of fetal anomalies
  • Genetic counseling for patients with late pregnancy and genetic disorders
  • Amnio test, hysteroscopy
  • NIPT(Non-invasive Prenatal genetic Testing)
  • Examination for causes of recurrent implantation failure
