Parathyroid surgery among pediatric population is an exceptional event. Sometimes, chronic renal failure cause independent and uncontrolled parathyroid overfunction; in this situation, a pediatric surgeon may be required. We report herein three kidney transplant patients who were diagnosed of tertiary hyperparathyroidism. Medical treatment didn't control the disease, so total parathyroidectomy with autotransplant in the forearm was indicated. The two patients who underwent surgery are free of the disease with a follow-up period of 6 and 26 months respectively. The other patient died a few days before the operation.
