[A new method of lymphadenography of the regional lymph nodes of the human urinary bladder. Findings relevant to cancer of the bladder (author's transl)].

Experience with and findings of a new method of indirect lymphography (endovesical lymphography) for roentgenologic visualization of lymph nodes and lymphatic vessels of the human urinary bladder are presented. After injection of Lipiodol Ultrafluid into the submucosal layer of the bladder wall all regional lymph node groups could be demonstrated. In cases of carcinoma of the bladder, endovesical lymphography provides early evidence of beginning carcinomatous infiltration of regional lymph nodes. Pedal lymphography as used thus far, provides information only about advanced lymphatic metastatic spread. It is possible that endovesical lymphography will yield new information leading to more accurate treatment of vesical carcinoma in terms of tumor staging.
