Abstract: Objective: To investigate the diagnosis and treatment of the renal neoplasm with calcification. Methods: Retrospectively summarized the clinical data of the 2 patients with calcific renal neoplasm admitted in our hospital from the May to July in 2014, then analyzed and discussed the clinical manifestations, diagnosis and treatment combined with the literatures. Results: The two cases were both suspected of renal malignant tumor preoperatively. The case 1 was a 32-year-old male, laparoscopic partial resection of the left kidney was performed, and the postoperative pathology was clear cell carcinoma (Fuhrman level I). The case 2 was a 18-year-old male, partial resection of the right kidney was performed because of the tumor size, and the postoperative pathology was adult nephroblastoma. Conclusion: The calcific renal neoplasm is rare clinically, the property determination depends on postoperative pathology, and as to the choice of surgical method, the patients` age, the tumor size and the tumor location should be taken into consideration, and intraoperative frozen should be performed when necessary.
