Ureteral obstruction secondary to metastases from distant primary tumors may be studied by urography, pyelography, venography and lymphagiography. An added dimension to the study of this disease process is obtained by the use of sonography and computed tomography since these techniques are better able to demonstrate the extent of the disease in the retroperitoneum.
远处原发性肿瘤转移所致的输尿管梗阻可通过尿路造影、肾盂造影、静脉造影和淋巴管造影进行研究。由于超声检查和计算机断层扫描能够更好地显示腹膜后疾病的范围，因此使用这些技术可为该疾病过程的研究增添新的维度。
