title: Transurethral ultrasound scanning in the evaluation of invasive bladder cancer.
abstract: 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.
