How Cysview Works

Historically, bladder cancer patients are at high risk for disease recurrence and progression,1 which could be due in part to missed tumors and incomplete surgeries because not all cancerous tissue is easy to see under white light. Moving forward, with the availability of Blue Light Cystoscopy with Cysview, that trend may shift.

Cysview is absorbed by bladder cancer tumors and causes then to glow bright pink under blue light, making them much easier to see. With this breakthrough visual advantage, physicians can perform more thorough bladder evaluations and more complete resections of bladder cancer tumors. This advanced level of care may lead to better disease management decisions.2

Cysview goes into the bladder before a cystoscopy procedure

1About one hour prior to a cystoscopy, the bladder cancer patient has about 2 oz of the Cysview solution placed into the bladder via a catheter.

2No less than one hour later, the urologist conducts the cystoscopy procedure to examine the bladder, first under white light to observe anything suspicious.

3Then, when the urologist switches to blue light, the Cysview causes tumors to glow bright pink, thereby making easier for the doctor to remove affected areas.
