泌尿器科領域におけるリンパ節シンチグラフィーの有効性に関する臨床検討

Abstract

99nTc-rhenium collidを用いたリンパ節シンチグラフィーを31症例に施行した.病理検索との比較ではoverall accuracy 83%, sensitivity 86%, speciticity 80%となり悪性腫瘍のリンパ節転移の検索, 並びにその進展度診断における補助診断法として有用と思われた.本法は手技が容易で, 頻回施行可能であり, また生理的なリンパ節の状態を把えうる特徴がある

Clinical efficacy of lymphoscintigraphy was evaluated in 31 cases of urological disease. To diagnose metastatic change of malignant tumor, 99mTc-rhenium colloid (5mCi) was administrated from bilateral pedal region. Of these patients 12 had true positive finding, 2 had false positive finding, 2 had false negative finding, and 8 had true negative finding defined by lymphoscintigram and pathological finding. Overall accuracy of lymphoscintigraphy revealed 83% in correlation of pathological finding, 78% in lymphangiography. Accuracy between lymphangiography and pathological finding was 80%. The overall clinical efficacy of lymphoscintigraphy was the same as lymphangiography. The merit of this method was that we can examine easily, painlessly, and frequently.
