泌尿器科領域に於けるLymphographyの検討

概要

論文の詳細を見る
The methods, clinical applications and complications of lymphography were briefly reviewed and evaluated. Several new trials were performed on lymphography. The conclusions of our trials are as follows; 1) Our technique to visualize the internal iliac lymphatic system in scintigram with ^<198>Au colloid injected into periprostatic tissue was successful to a certain degree. However, it is difficult to know metastasis in lymph nodes by the scientigram. 2) It does not give any advantage to take lymph-scintigram following ^<131>I popiodol injection into lymphatic channels, comparing with usual lymphography. 3) It is difficult to tell early lymphatic metastasis by the present technique of lymphography. 4) Lymph nodes taken at surgery 2 weeks after ^<131>I popiodol injection (300-500 μc) revealed stronger succinic dehydrogenase and lactic dehydrogenase activities in histochemical staining than those given usual popiodol. There is a possibility that lymphography with radioisotopes might be useful to treat tumors or prevent dissemination of metastatic cells in lymph nodes.
