One hundred and sixty-six patients suspected of having bladder tumours underwent transurethral ultrasound scanning before cystoscopy. Forty-nine patients had no tumour either at cystoscopy or on ultrasonography. Nine of the remaining 117 patients (8%) had false positive results and in a further 8 (7%) the ultrasound failed to show the tumour. The diagnostic accuracy for superficial tumours was 73%, whereas the accuracy in assessing muscle infiltrating and more advanced tumours was almost identical, 58-59%. It is concluded that transurethral ultrasound scanning does not add to the information obtained from cystoscopy and bimanual palpation in patients with bladder tumours.
166例疑似膀胱肿瘤患者在膀胱镜检查前行经尿道超声扫描。49例患者在膀胱镜检查及超声检查中均未发现肿瘤。其余117例患者中有9例（8%）出现假阳性结果，另有8例（7%）超声检查未能显示肿瘤。浅表肿瘤的诊断准确率为73%，而评估肌肉浸润性及更晚期肿瘤的准确率几乎相同，为58 - 59%。结论是，对于膀胱肿瘤患者，经尿道超声扫描并未增加从膀胱镜检查和双合诊中获得的信息。
