title: Ureteral involvement by metastatic disease.
abstract: 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.
