OBJECTIVE To assess the test performance and clinical effectiveness of narrow band imaging (NBI) cystoscopy compared with white light imaging (WLI) cystoscopy in people suspected of new or recurrent bladder cancer. METHODS Literature on NBI cystoscopy in the diagnosis of bladder cancer was searched in PubMed, EMBASE, Cochrane Library, MEDLINE and CNKI, with hand searching of relevant congress abstracts and journals. The literature was selected according to inclusion and exclusion criteria. The Meta-DiSc1.4 software was used to review management and analysis. RESULTS Eight studies including 1022 patients assessed test performance. On a per-person analysis, the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of NBI and WLI were respectively 0.943 (95% CI 0.914-0.964) and 0.848 (95% CI 0.803-0.885), 0.847 (95% CI 0.812-0.878) and 0.870 (95% CI 0.831-0.903), 7.038 (95% CI 3.357-14.754) and 6.938 (95% CI 2.052-23.465), 0.054 (95% CI 0.012-0.237) and 0.181 (95% CI 0.091-0.361), and 185.32 (95% CI 45.714-751.26) and 42.931 (95% CI 8.088-227.88). The area under the curve and Q* of NBI and WLI were respectively 0.9781 and 0.8944, and 0.9337 and 0.8253. For the characterization of carcinoma in situ, the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of NBI were 0.927 (95% CI 0.878-0.960), 0.768 (95% CI 0.730-0.802), 4.545 (95% CI 2.820-7.325), 0.125 (95% CI 0.051-0.304) and 48.884 (95% CI 15.642-152.77) on a per-person analysis. The area under the curve and Q* were 0.9391 and 0.8763. CONCLUSION NBI is an effective method for the identification of abnormal lesions including carcinoma in situ and can provide higher diagnostic precision of bladder cancer than WLI.
