Objective To investigate the diagnosis and treatment of primary retroperitoneal tumor. Methods The clinical data of 46 patients with primary retroperitoneal tumor confirmed by pathology after operation before 1990 ~ 2001 were retrospectively analyzed. Results Of the 46 cases, 31 cases were malignant and the average duration of malignant tumor was only 36 months. The average diameter of the tumor was 13 cm, the complete resection rate was 51.6% and the 5-year survival rate was 41%. The benign and 15 cases were benign Long tumor average length of 16 months, average tumor diameter 7cm, complete resection rate of 91%. Conclusions BUS and CT have a great effect on preoperative evaluation. Complete surgical resection is the key to treatment
