The UC Davis Department of Urology now offers fluorescence, also called blue light, cystoscopy during surgery for bladder tumor removal. The department began using this technology in September of 2015, the first in the region to do so.
Traditionally, if a patient has bladder cancer and is recommended surgery, a urologist will use white light and a camera to help identify tumors for removal. Fluorescence cystoscopy, however, uses a different wavelength so that the bladder and healthy tissue appear blue, while tumors are red.
“This helps us better visualize small tumors that may not be identified under white light,” said Marc Dall’Era, associate professor and vice chair of the Department of Urology. “The blue light also helps the surgeon see the edges of the tumor to enable a more complete surgical removal of the tumor.”
The thorough view and tumor removal reduces the chance that the cancer will recur. This treatment advance led the American Urological Association to add fluorescence cystoscopy to their recommended guidelines for treating bladder cancer.
UC Davis uses Cysview as its imaging agent for fluorescence cystoscopy.
