经腹壁超声在膀胱肿瘤诊断与分期中的意义

Transabdominal ultrasonography for the diagnosis of bladder tumor

行经腹Ｂ超检查临床疑诊为膀胱肿瘤患者２９９例，经与膀胱镜检和术后病理结果对照，２７１例证实为膀胱肿瘤，１０例为非膀胱肿瘤，１８例经腹Ｂ超漏诊。本组经腹Ｂ超诊断准确率为９０．６％（２７１／２９９），误诊率为３．３％（１０／２９９），漏诊率为６．０％（１８／２９９）。经腹壁超声判断膀胱肿瘤分期总的正确率为８８．６％（Ｔ_１期肿瘤８９．１％，Ｔ_２期为８６．８％，Ｔ３期为８７．５％，Ｔ_４期为１００．０％）。经腹壁超声方法简单，患者无痛苦，对膀胱肿瘤诊断与分期的准确性较高，应作为膀胱肿瘤的常规检查方法。

Transabdominal ultrasonography was carried out for 299 patients suspected of bladder tumor and bladder tumor was diagnosed in 281.Among them,the diagnosis was comfirmed on cystoscopic and pathologic studies in 271(90.6%).The misdiagnosis rate has been 10(3.3%)and the diagnosis was missed in 18(6.0%).The overall accurate staging rate was 88.6%,being 89.1% in stage T_1 tumors,86.8% in stage T_2,87.5% in stage T_3 and 100% in T_4.Transabdominal ultrasonography is simple,atraumatic and accurate and therefore should be routinely adopted for patients suspected of bladder tumor.
