Abstract「要旨」 腎尿路系疾患の総合イメージ診断のうち, 比較的侵襲性の少ない腎シンチグラフィーと超音波断層法との併用法につき, 両者の比較あるいは, 他の検査法との比較もまじえて, その臨床的有用性を検討した. 対象症例は, 腎癌症例35例, およびヨードアレルギーを有した巨大単純性腎嚢胞症例1例で, 前者では超音波断層法により全例でsolid mass lesionとして認められたのに対して, 腎シンチグラフィーでは, 3例 (8.6%) において, いわゆるcystic patternを示し, また, これらの血管撮影像ではhypovascularあるいはavascular mass lesionとして認められ, 腎癌の診断における超音波断層法の有用性が示唆された. 一方, 後者のように, IVPの実施が不適当な症例においては, 超音波断層法およびCTだけでは十分な情報は得られず, 腎シンチグラフィーの有用性が認められた. 両検査法を併用することにより, 互いの欠点を補うことが可能であり, さらに, 両者ともに, 侵襲性が少なく, 反復検査が容易など, 腎腫瘤性病変の診断における両者の併用法の有用性が認められた.

Abstract[Summary] Excretory urography (IVP) has been considered to be a suitable screening technique for urological disorders. In the cases suspected to have space occupying lesions in the kidney by IVP, a more precise technique with the minimum risk is mandatory as the secondary diagnostic means. We have been examining the space occupying lesions in the kidney, using noninvasive combined method, renoscintiphotography and ultrasonography. Reviewing 35 cases of renal cancer, both techniques have contributed in making correct diagnoses in most cases, however radionuclide flow study have failed to detect it in three cases. In latter cases renoscintiphotos demonstrated cold areas in both perfusion and accumulation phases, and renal angiograms have also shown hypovascular or avascular lesions. Ultrasonograms revealed solid mass lesions respectively. Radical nephrectomies were performed without percutaneous biopsy in these cases, and their pathological findings were of clear cell carcinoma. On the other hand, in the cases of iodine allergy or impaired renal function, the combined study has provided satisfactory information to make a correct diagnosis. In conclusion the combined studies, renoscintiphotography and ultrasonography are quite useful for diagnoses of renal mass lesions, especially in the case of hypovascular or avascular tumor. As screening test of the urological disorders, these studies can replace IVP in the case of iodine allergy and/or impaired renal function.
