[Radiation-induced kidney diseases after treatment of juvenile neoplasms]

3 children with malignant tumors in one kidney were treated with radiation in doses of 30 (3 weeks), 35 (6 weeks), and 33 Gy (8 weeks). The clinical and histological findings of radiation-induced nephritis from 2 children are demonstrated. In the third case radiation was performed because of adrenocortical carcinoma. 10,5 years after radiation the child developed a renal cell carcinoma.
