Introduction: Primary retroperitoneal tumors account for 3% of all tumors, with sarcoma and schwannoma being the most common. Their growth period is rather long, without presence of characteristic symptoms related to the location and tumor size. Basic therapeutic procedure is complete surgical removal of tumor. Definitive diagnosis is made intraoperatively and after hystopathological examination. Objective: To present the results of surgically treated retroperitoneal tumors localized in female pelvis. Method: Eight (8) patients with different histological types of retroperitoneal tumors were operated in the period 2001-2010. Only in 4 (50%) cases, imaging diagnostic methods reliably confirmed retroperitoneal localization of pelvic tumors. Stage of the disease was determined according to staging classification of soft tissue sarcomas. Results: In the period 2001-2010, 4015 of women were operated for different pelvic tumors, out of which 8 (0.19%) had retroperitoneal tumors. 5 (62.5 %) patients had malignant tumors of mesenchymal origin (sarcomas), while 3 (37.5%) patients had benign tumors. In all cases, tumors were completely removed. Average length of operation was 189 minutes, and intraoperative blood loss was 360 ml. In 2 (25%) patients with malignant retroperitoneal schwannomas, bleeding from presacral veins and arteries of greater omentum occurred following the surgery, which required second look surgery. Conclusion: In spite of utilization of modern diagnostic methods, primary retroperitoneal tumors are in 50% of cases discovered intraoperatively. Successful treatment means complete surgical tumor removal. The total of 6 (75%) patients is alive and without clinical signs of tumor, while average survival rate is 4.3 years.
