[Endourological imaging with narrow band imaging].

Narrow band imaging (NBI) is an optical diagnostic procedure which utilizes the narrowing of the wavelength of visible light in the range between 415 and 550 nm. The NBI is mostly used for the diagnostics of inflammation or tumors of the gastrointestinal tract. The first investigations for diagnostics of bladder cancer using NBI date from 2008. Currently data on resection, follow-up and recurrence behavior of bladder cancer are available. In all publications NBI was tested against white light. A randomized study comparing NBI with photodynamic diagnostics has not yet been carried out. In this article current study results on the application of NBI for bladder cancer will be presented.
