OBJECTIVES: A single centre, retrospective trial was performed trying to assess the impact of NBI cystoscopy in cases of non-muscle invasive bladder tumors (NMIBT) by comparison to the standard approach. Our goal was to determine the superiority of the new method in terms of detection rates and subsequent postoperative treatment changes. MATERIALS AND METHODS: A total of 320 NMIBT suspected consecutive cases were enrolled in the study. The inclusion criteria were represented by hematuria, positive urinary cytology and/or ultrasound suspicion of bladder tumors. All patients underwent WLC and NBI cystoscopy. Standard transurethral resection of bladder tumors (TURBT) was performed for all lesions visible in WL and NBI guided resection for solely NBI observed tumors. RESULTS: The overall NMIBT and CIS patients' detection rates were significantly improved for the NBI evaluation ((94.9% versus 88.1% and 95.7% versus 65.2%). Also, on a lesions' related basis, NBI cystoscopy emphasized a significantly superior diagnostic accuracy concerning the CIS, pTa and overall NMIBT formations ((95.2% versus 60.3%, 92.8% versus 83.9% and 94.1% versus 82%). Additional tumors were diagnosed by NBI in a significantly higher proportion of CIS, pTa, pT1 and NMIBT patients (56.6% versus 8.7%, 28% versus 10.3%, 30.3% versus 10.6% and 31.6% versus 9.4%). As a result of these supplementary findings, the postoperative treatment was significantly improved in a substantial proportion of cases (15.4% versus 5.1%). CONCLUSIONS: NBI cystoscopy represents a valuable diagnostic alternative in NMIBT patients, with significant improvement of tumor visual accuracy as well as detection rates. This approach provided a substantial amelioration to the risk category stratification and subsequent bladder cancer therapeutic management.
