The ten specialty groups cover all the specialized medical areas of pediatrics, providing all patients with advanced medical care services.
We have accepted many patients referred from affiliated hospitals as an advanced pediatric medical care institution in western Japan. We employ the most advanced medical techniques, especially to treat pediatric hematological/tumor diseases (stem cell transfusion and WT1 peptide vaccination), and further perform ambulatory peritoneal dialysis for pediatric patients with chronic renal failure, enzyme replacement therapy and hematopoietic stem cell transplantation for pediatric patients with lysosomal disease, polysomnography for pediatric patients with sleep disorders, examination for surgical indications and internal medication for intractable epilepsy, diagnosis and treatment of pediatric patients with endocrine disease, diagnosis of pediatric patients by endoscopy and/or liver biopsy, and pediatric transplantation for pulmonary hypertension and cardiomyopathy.

Considerations in referring your patients to Pediatrics

In principle, the first medical examination is by appointment only. Please contact the Social Service Department to get an appointment, and communicate the appointment day and time to a family member or attendant of your patient. For the patient without a prior appointment, a family member or attendant of the patient must visit during the doctor's office hours. For patients who need to be urgently admitted to our hospital, please be sure to contact the reception counter for outpatients in advance.
