Summary 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.
