[A case of successful hypospadias repair without infection using recombinant human granulocyte-colony stimulating factor (rhG-CSF) for idiopathic neutropenia].

A boy aged 1 year 8 months, who was referred to our hospital because of hypospadias, was followed for 17 months under a diagnosis of idiopathic neutropenia. He was given recombinant human granulocyte colony-stimulating factor (rhG-CSF) at a dosage of 37.5 micrograms/day for 2 days preoperatively. His absolute neutrophil count in peripheral blood increased to more than 500/microliter, and hypospadias repair (free graft method) was performed. RhG-CSF was administered on the first, sixth, and eleventh days after the operation, and the postoperative course was uneventful. During pediatric surgery in patients with neutropenia, appropriate administration of rhG-CSF may be useful for preventing infection.
