New techniques have been introduced to improve the physician’s ability to detect small, non-muscle-invasive tumors that may not be seen with conventional cystoscopy. In certain situations, Chesapeake Urology physicians may utilize Narrow Band Imaging (NBI) Cystoscopy, an image enhancement technology with greater sensitivity for detecting bladder tumors. The technology takes advantage of the benefits of varying wavelengths of white light without the need for dyes or drugs.

How NBI is Performed
Narrow Band Imaging cystoscopy is performed in your urologist’s office or one of Chesapeake Urology’s Summit ambulatory surgery centers (ASC). The procedure is performed the same way as a diagnostic cystoscopy with the special imaging technology attached to the tip of the cystoscope.
NBI does not require that you take medications or have any type of dye injection to enhance visualization.
Because this technology does not require preparation by the patient, the physician may decide to utilize the NBI cystoscopy during the course of a traditional cystoscopy.
NBI can also be utilized for biopsy or transurethral resection of a bladder tumor (tumor removal).
