Abstract「要旨」片側性非腫瘤性腎疾患90例を対象とし, 投与後1分〜4分の初期イメージ上の99mTc-DTPAの腎実質への集積変化と対比しながら, 腎RIアンギオグラフィにおける腎血流変化の有用性をイメージ上より検討し, 以下のごとき結果を得た. 慢性腎盂腎炎13例では, 腎血流変化, 実質への集積低下の出現頻度には差違がみられなかったが, 腎動脈狭窄13例中2例では, 実質への集積低下が異常としてみられなかったにもかかわらず, 腎血流変化が片側性病変の存在を示唆する異常としてみられた. また, 閉塞性尿路疾患では明らかに異常ありと判定した場合, 腎血流変化, 実質への集積低下の出現頻度に差違がみられなかったが, equivocal所見である僅かの変化も含めると, 腎血流低下の出現が高頻度にみられた. 以上, 片側性腎疾患の評価には, 腎実質機能の評価に附随して, 腎血流評価の有用性が示された.

Abstract[Summary] A total of 90 patients with unilateral nonfocal renal disease (58 patients with obstructive uropathy, 13 patients with renal artery stenosis, 13 patients with chronic pyelonephritis, 3 patients with renal tuberculosis and 3 patients with a- or hypogenesis) were examined with the method of serial dynamic imaging of Tc-99m DTPA including radionuclide angiography. And the diagnostic significance of renal perfusion abnormality on radionuclide angiogram was qualitatively evaluated compared to that of renoparenchymal uptake abnormality on the image from one min. to four min. after intravenous administration of Tc-99m DTPA. In fifty-nine out of 90 patients (65%) with unilateral nonfocal renal disease, both perfusion and parenchymal uptake abnormalities were found at the involved side. In two of 13 patients with renal artery stenosis, however, the unilateral hypoperfusion was only found as the evidence of unilateral disease on radionuclide angiogram although these did not show any parenchymal uptake abnormality. Moreover, four out of 58 patients with obstructive uropathy, did show the slight difference of renal perfusion between the involved and the univolved sides. and did not show any difference of parenchymal uptake between both sides. In the present study, the incidence of perfusion abnormality on radionuclide angiogram was slightly higher than that of parenchymal uptake abnormality on the image from one min. to four min. in unilateral renal disease. Therefore, it is suggested that the radionuclide angiography may be accepted as one of the routine nuclear medicine imagings for the evaluation of functional abnormalities in nonfocal renal disease.
