An analysis of 50 primary human retroperitoneal tumors is presented with emphasis on the urological aspect; 70-80% of the tumors were malignant, and sarcomas predominated. The tumor mass was palpable in over 70% of the cases. Frequent involvement of the urinary tract caused lumbar pain in 78% of cases. I.v. urography and retrograde pyelography were the greatest single aids in accurate diagnosis of primary retroperitoneal tumors, since over 70% showed abnormalities. Selective angiograms may define the size and operability of the tumor. When diagnosed, extirpation of the tumor was possible in only 30-40% of cases. Postoperative mortality was about 10%. Since 70% of these tumors were radiosensitive, radiotherapy improved the prognosis Survival for more than 2 yr after surgery was exceptional.
