The value of excretory cystography in diagnosing bladder tumours was assessed in a randomised study. The 10-min, 20-min, and post-voiding films of intravenous urograms of 75 patients with biopsy-proved bladder tumours and of 25 patients with proved normal bladders were randomly reviewed. Overall, 60 of 75 bladder tumours (80%) were correctly diagnosed by review of the roentgenograms. Specificity and sensitivity were comparable (94 and 96% respectively) for patients with papillary tumours greater than or equal to 0.5 cm in diameter, but specificity was low (23%) for those with tumours smaller than 0.5 cm. It is concluded that excretory cystography makes a considerable contribution to the establishment of the diagnosis of papillary bladder tumours greater than or equal to 0.5 cm in diameter.
在一项随机研究中评估了排泄性膀胱造影在诊断膀胱肿瘤方面的价值。对75例经活检证实患有膀胱肿瘤的患者和25例经证实膀胱正常的患者的静脉尿路造影的10分钟、20分钟及排尿后影像进行了随机复查。总体而言，通过对X线片的复查，75例膀胱肿瘤中有60例（80%）被正确诊断。对于直径大于或等于0.5 cm的乳头状肿瘤患者，特异性和敏感性相当（分别为94%和96%），但对于直径小于0.5 cm的肿瘤患者，特异性较低（23%）。结论是，排泄性膀胱造影对直径大于或等于0.5 cm的乳头状膀胱肿瘤的诊断确立有相当大的贡献。
