膀胱腫瘍24例の40腫瘍を対象とし経尿道的超音波断層法により腫瘍の描出と浸潤度判定を試みた.腫瘍の大きさが直径0.5 cm以上の場合有効な走査をおこないえたが,0.5 cm以下と膀胱頂部・頸部に発生した腫瘍の走査は困難な場合が多かった.全層有効標本の病理学的診断との対比では78%の一致率を得たTransurethral ultrasonographic examination was performed on a total of 24 patients with 40 bladder tumors to evaluate the accuracy of the method to detect bladder tumors and to compare ultrasonographic staging of bladder tumors with pathological staging. The results showed that it was difficult to detect bladder tumors of any size located in the bladder neck or dome and those less than 0.5 cm in diameter located anywhere, indicating the difficulty in tumor staging. On the other hand, diagnostic accuracy was approximately 90% for the tumors larger than 0.5 cm in diameter. Therefore, if a tumor with a diameter larger than 0.5 cm is detected by cystoscopy, we believe that urethral ultrasonographic examination should be performed as a routine protocol after the cystoscopy.
