The discomfort caused by cystoscopy to the patient with superficial bladder tumor has led to the routine use of other less invasive but similarly reliable procedures. We performed a two-year comparative study of cystoscopy versus abdominal ultrasonography/cytology in 90 patients. Two hundred procedures were performed for each method of evaluation. Together, the sensitivity and specificity of both procedures were 61% and 98%, respectively. The positive and negative predictive values were 94% and 87%, respectively. These good results have permitted us to change the follow-up protocol of these patients such that currently ultrasonography and cytology are performed once every 6 months, and cystoscopy is used only for those cases with clinical features suggestive of recurrence and a negative work up of those with a negative scan and positive cytology.
膀胱镜检查给浅表性膀胱肿瘤患者带来的不适，促使人们常规采用其他侵入性较小但同样可靠的检查方法。我们对90例患者进行了一项为期两年的膀胱镜检查与腹部超声/细胞学检查的对比研究。每种评估方法都进行了200次检查。两种检查方法的敏感性和特异性分别为61%和98%。阳性预测值和阴性预测值分别为94%和87%。这些良好的结果使我们能够改变这些患者的随访方案，即目前每6个月进行一次超声检查和细胞学检查，只有那些具有复发临床特征的病例以及扫描结果为阴性而细胞学检查为阳性但进一步检查结果为阴性的病例才使用膀胱镜检查。
