Abstract：Objective: To evaluate the value of CT in diagnosing and staging of nephroblastoma in children. Methods: Clinical and CT manifestations of nephroblastoma in 27 cases with integrate imaging material proved operatively and pathologically were summarized. Results: Thirty-six primary tumors were found in 33 kindeys, 11 in the right kidney, 10 in the left kidney, and 6 in both kidneys. The pathological result of the 33 cases includes epithelial type(10 cases), blastemal type(7 cases), stromal type(9 cases), composite type(7 cases), anaplastic type(3 cases), The preoperative staging of the tumor: stage I in 9 cases, stage II in 7 cases, stage III in 3 cases, stage IV in 2 cases, and stage V in 6 cases. The accurate rate of tumor staging was nearly 88.89%. Conclusions: The CT inspection can show edge, site, size of the tumor, and accurately evaluate tumor invasion, metastasis. It has important value to determine the nature, staging, following-up of nephroblastoma.
