经腹壁超声在膀胱肿瘤诊断与分期中的意义

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 for the diagnosis of bladder tumor

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.
