Blue Light Cystoscopy
The Blue light (Hexaminolevulinate fluorescence) cystoscopy involves instilling a photosensitizing agent, such as Cysview, into the bladder. The Blue light cystoscopy contains a light source and light is transmitted through a fluid light cable connected to an endoscope to light up the area to be observed. The photosensitizing agent preferentially accumulates porphyrins in malignant cells as opposed to nonmalignant cells of urothelial origin. Under subsequent blue-light illumination, neoplastic lesions fluorescence red, enabling visualization of tumors. The Blue light cystoscopy is used to detect non-muscle invasive papillary cancer of the bladder.

Famous quotes containing the words blue and/or light:
“While my hair was still cut straight across my forehead
I played about the front gate, pulling flowers.
You came by on bamboo stilts, playing horse,
You walked about my seat, playing with blue plums.”

“Ex oriente lux may still be the motto of scholars, for the Western world has not yet derived from the East all the light which it is destined to receive thence.”
