—McCown30 stated that primary carcinoma is rare, and that the paucity of symptoms makes diagnosis difficult. Early treatment is necessary to secure beneficial results, since tumors of this type result in widespread and rather early metastasis. He reported a case of tumor of the ureter. After various examinations, he concluded that a tumor of the ureter or of the kidney and ureter was present, and retroperitoneal nephrectomy was done through a lumbar incision.
