|Abstract:||(1)自験例7例の腎癌において,CT.超音波断層法,動脈造影法のそれぞれの方法で,術前stage診断をおこない,手術または剖検によるstage診断と比較した.(2) stage 1の診断については,CT.動脈造影法が有用であったが,超音波断層法では,stage 2との鑑別が困難であった.(3) stage 4Aの診断は,CT.超音波断層法で可能であった|
Preoperative diagnosis of stage is very important in choosing the best treatment for renal cell carcinoma. The present study reports the accuracy of preoperative tumor staging by CT, ultrasonography (U. I. Octoson) and angiography in 7 cases of renal cell carcinoma. The preoperative stagings were compared with operative or autopsy findings. By operation and autopsy of the 7 cases, 3, 1 and 3 cases were confirmed to be at stages 1, 2 and 4A, respectively. In stage 1 which was confirmed by operation, CT and angiography seemed to be more useful than ultrasonography. It was difficult to distinguish stage 1 from stage 2 by ultrasonography, because the perinephric fatty tissue was not demonstrated as a distinct structure on the echogram. CT and ultrasonography were valuable in making the preoperative diagnosis of stage 4A cases. In conclusion, a more accurate preoperative staging of renal cell carcinoma would be possible when the diagnosis is based on the findings obtained by CT, ultrasonography and angiography.
