Abstract
Narrow band imaging (NBI) cystoscopy is a novel optical technology designed to enhance visual detection of bladder tumors over conventional white light imaging (WLI) cystoscopy. NBI highlights the neovascularity of tumors contrasted with normal mucosa. NBI cystoscopy detects more bladder tumors than WLI cystoscopy and may identify high-grade dysplasia, overlooked by WLI cystoscopy. NBI cystoscopy improves evaluation of response to intravesical therapy, and NBI-assisted fulguration, and transurethral resection appears to result in fewer tumor recurrences compared to surgical treatment using WLI cystoscopy. NBI poses no risks to patients and is cost-effective. The economic burden is limited to the cost of the light source and camera. NBI is best used as a supplement procedure to WLI cystoscopy in the diagnosis, evaluation, and treatment of bladder tumors.
