New imaging techniques are improving cancer detection during cystoscopy, helping doctors identify and remove tumors more accurately.
Blue Light Cystoscopy (BLC) with Cysview uses a photosensitizing agent, hexaminolevulinate HCl, instilled into the bladder about an hour before the procedure. Cancer cells absorb the agent and glow bright pink or red under blue light, while healthy tissue appears blue. This enhanced contrast makes it easier to detect difficult-to-see tumors, including flat lesions and carcinoma in situ, improving detection rates and reducing recurrence.
Narrow Band Imaging (NBI) enhances tumor visibility by using specific light wavelengths to highlight areas with increased blood vessels, a common feature of cancerous tissue. Unlike BLC, NBI does not require a photosensitizing agent and can be used during standard cystoscopy, offering a practical method to improve tumor identification and guide more precise treatment.
