経尿道的超音波断層法による膀胱腫瘍の浸潤度判定

Abstract

本法施行後, 手術により組織学的に浸潤度を確かめ得た39症例について, 正診率は, 全症例では82.9%で膀胱全摘除術症例では, 83.3%と良好であった.なお, 本法は, 描出力の鮮明さや描出範囲の広さ, 読影の容易さなどにおいて, 経直腸摘超音波断層法より優れていた

A transurethral ultrasonographic study of diagnosing the stage of bladder tumors was made on 35 cases whose pathological stages were confirmed by transurethral resection or total cystectomy. Ultrasonographic diagnoses were in accordance with the pathological stages in 29 (82.9%) out of 35 cases. Restricted to 12 cases whose histological findings were examined by total cystectomy, the accuracy was 83.3%. Transurethral ultrasonography is considered to be a very useful method for bladder tumor staging.
