NBI Cystoscopy Sheds Light on Bladder Cancer

Thursday, March 26, 2015

Bladder Cancer is a type of cancer that can affect both men and women, however, it is much more prevalent in men. It can come at any age but is most commonly seen in older adults. The average age of diagnosis is around 65.Oftentimes, there are no symptoms associated with this cancer in its early stages. Approximately 80% of patients experience painless hematuria, or blood in their urine, that is detected either by sight or through lab tests. Other symptoms may include frequent, burning or painful urination. In the later stages of this disease, patients may experience weight loss, or pain in the abdomen, back or pelvis.When it comes to the diagnosis of bladder cancer by your doctor, there are a few common procedures used. Among these is the cystoscopy. The cystoscopy is a procedure in which a doctor uses a narrow tube, equipped with a camera on its tip, to navigate through your urethra to your bladder to try to locate abnormalities such as lesions or tumors. This tube shines a white light on the inside of the bladder and the lens on the tube allows the doctor to view the area.A new variation of the white light cystoscopy called Narrow-band Imaging has just been approved by the FDA. According to a new study, the difference between the new procedure (NBI) and existing white light cystoscopies is that NBI expands visibility of tissues for biopsies and tumor margin identification.This enhanced visibility is achieved through the use of blue and green lights, which are absorbed by the blood. Specifically, the blue lights highlight shallow capillaries and the green highlight the deeper veins.It is still too early to tell whether this will improve detection of bladder cancer. If, however, the technology does become adopted and is an improvement on the current diagnosis process, patients could experience improved outcomes.Other procedures used for detecting bladder cancer include:Biopsy – This can be done while a cystoscopy is being performed. The doctor will pass a small tool through to the bladder to collect a sample to be used for testing.Urine cytology – A urine sample can be analyzed and checked for cancer cells.Imaging tests – A doctor can examine the structure of your urinary tract using imaging test, in which a dye is injection into your veins and then imaged.  A CAT scan is used to help stage the disease, and to determine if the cancer has spread beyond the bladder.To learn more about the different types of bladder cancer diagnosis procedures, please consult with your doctor.The following is a link to an overview video on Bladder Cancer with our own Dr. Hardee: https://www.youtube.com/watch?v=5vIYn3P0sto *The Urology Team has qualified and experienced doctors at three convenient locations in the Austin area.
