[Sequential combined liver-kidney transplantation for a one-year-old boy with infantile primary hyperoxaluria type 1].

We present the case of a one-year-old male patient with infantile primary hyperoxaluria type 1 (PH1). The patient visited hospital because of growth delay and poor feeding when he was six months old, and was diagnosed as PH1 with chronic renal failure. He underwent peritoneal dialysis until receiving a living-related liver transplantation when he was seventeen months old, and after the operation, underwent hemodialysis or hemodiafiltration four times per week.
