| Abstract | 「要旨」 過去2年半に施行された402症例の動態腎スキャンについて, 欠損像を示した126症例の疾患別分析を行い, 血流パターンの分類から腎内占拠性病変の質的診断の可能性と限界に関して検討した. 腎欠損像への血流パターンを血流の多寡とその分布像から7型に分類した. 82例(65%)が乏血性パターン(0 〜 II型)を示し, 50例(61%)が嚢腫疾患であった. 腎実質と同程度(III型)あるいはそれ以上の多血性パターンを示した症例は17例(13%)で, 腎悪性腫瘍が11例(65%)であった. 特徴的な血流分布像として分類されたドーナツパターン(V型)は10例(8%)でその全例が充実性腎腫瘍であった. 手術例は39例(31%)で, 充実性腎腫瘤と嚢腫疾患の術前診断率は93.3%であった. 誤診例は, ドーナツパターンを示し周辺部血流が乏血状であった腎細胞癌と過誤腫(angiomyolipoma)の各1例を嚢腫と診断していた. 腎内占拠性病変の質的診断は, 嚢腫疾患や腎細胞癌に定型的な血流パターンを理解することで90%以上の確率で可能であった. ただし, 腎充実性腫瘍の一部には非定型的な乏血性パターンを示す例が存在し, また嚢腫疾患でも腎内占拠部位により血流パターンの判定が容易でない症例が含まれ, このような症例に対しては動態腎スキャンによる質的診断の限界を感じた. |

| Abstract | [Summary] Four hundred two cases of dynamic renal scintigraphy using 99mTc-gluconate performed for these two and a half years were reviewered retrospectively. A hundred twenty six were interpreted as renal parenchymal defects disclosed on static images. In these cases, thirty nine cases have been operated and thirty one have not yet been denititively diagnosed. Renal cystic diseases were most in number. All of renal cysts were completely correct in a preoperative diagnosis. However, one of hypernephromas and one angiomyolipoma were interpreted as renal cyst rather than solid mass. These cases showed hypovascular rim with central photo deficiency which was confirmed to be consistent with central necrosis by operation. The diagnostic accuracy distincting solid tumor and cyst were 93.3%. From a pattern of a blood perfusion to renal defects, were over ninty percents of renal space-occupying lesions distinctly interpreted as solid renal tumor. However, solid tumor which shows hypovascular rim with central photon deficiency were very resemblling to renal cyst. Necessity of further diagnostic approach in such cases should be kept in mind on discerning spaceoccupying lesions demonstrated on the dynamic renal scintigraphy. |
