The first blind, prospective, randomised comparison of flexible cystoscopy with rod-lens cystoscopy was carried out on 53 consecutive volunteers with bladder tumours or haematuria. Three patients' recurrences were missed on flexible cystoscopy and 3 others on rod-lens examination. It was expected that the 9% rate of missed tumours would lessen with increased experience of flexible cystoscopy, as 2 of them occurred in the first 12 examinations and all of the lesions missed were < 5 mm in diameter. Rod-lens cystoscopy, the accuracy of which appears to have been measured for the first time, was no more sensitive.
对53名患有膀胱肿瘤或血尿的连续志愿者进行了首次灵活膀胱镜检查与棒状透镜膀胱镜检查的盲法、前瞻性、随机对照研究。灵活膀胱镜检查漏诊了3例患者的复发情况，棒状透镜检查漏诊了另外3例。预计随着灵活膀胱镜检查经验的增加，9%的肿瘤漏诊率会降低，因为其中2例发生在前12次检查中，所有漏诊的病变直径均<5毫米。棒状透镜膀胱镜检查的准确性似乎是首次测量，其敏感性并不更高。
