The National Children's Hospital (NCH) was founded in 1965 as the first general children's hospital in Japan. It has practical functions only for infants and children. Another Jaspanese children's hospitals have almost the same condition as NCH, which lacks for functions of dealing older age patients. However, the number of admisions of the patients, who were treated in the early years and have reached more than 16 years old, is rapidly increasing. Environements at childre's hospital are not always covenient for the older patients not only in medical aspects but also in social aspects. Girls who underwent pelvic surgery or who have impaired hepatic, renal, or cardiac function are coming to their reproductible age. Pregnancy and delivery in such patients may be anticipated seriously risky. Pediatric surgeon, pediatrician, and obstetrician should be closely connected to treat high-risk pregnancy. Furthermore, children's hospitals should respond to maternal transportaion in cases of antenatal diagnosis. A faculity for the adult pracitce, incluidng obstetrics and gynecology, has become necessary in old children's hospitals in Japan.
