A series of 75 patients with retroperitoneal masses (60 malignant and 15 benign tumours) have been studied. Urography and angiography were employed. The results of the two methods are correlated. The following criteria are taken into consideration: a) site; b) nature; c) extension of the mass. The importance of a precise definition of the extension of the tumour is stressed. In fact this can greatly influence the choice of the therapy.
对75例腹膜后肿块患者（60例恶性肿瘤和15例良性肿瘤）进行了研究。采用了尿路造影和血管造影。对这两种方法的结果进行了对比。考虑了以下标准：a）部位；b）性质；c）肿块的范围。强调了精确定义肿瘤范围的重要性。事实上，这会极大地影响治疗方法的选择。
