We have studied the accuracy of transabdominal ultrasound (TAUS) in the diagnosis of early superficial bladder carcinoma. One hundred and twenty-six patients returning for check cystoscopy were scanned pre-operatively with the Technicare Autosector Scanner and the results compared with the endoscopic findings. Forty-four patients (37%) had a tumour recurrence. TAUS demonstrated a lesion in 50% of these with a false positive rate of 11%. The diagnostic accuracy was proportional to the tumour size (82% of patients with tumours above 5 mm were detected compared with 38% below 5 mm), but was not affected by grade, stage or position in the bladder. TAUS may prove a useful adjunct to cytology as a screening test for bladder cancer.
我们研究了经腹超声（TAUS）在早期浅表性膀胱癌诊断中的准确性。126例接受膀胱镜复查的患者在术前使用Technicare自动扇形扫描仪进行扫描，并将结果与内镜检查结果进行比较。44例患者（37%）出现肿瘤复发。TAUS在其中50%的患者中检测到病变，假阳性率为11%。诊断准确性与肿瘤大小成正比（肿瘤大于5mm的患者中82%被检测到，而小于5mm的患者中这一比例为38%），但不受肿瘤分级、分期或在膀胱中的位置影响。TAUS可能被证明是一种有用的辅助细胞学检查手段，作为膀胱癌的筛查测试。
