Urinary cystoscopy is an exam that allows observation into the interior of the bladder, particularly the inner wall, called the vesicle mucus membrane. The principle is to introduce a cystoscope into the bladder by passing through the urethra, the canal joining the bladder with the urinary meatus and permitting the evacuation of urine. The cystoscope is a thin tube equipped with optical fibers or with a mini video-camera. At the other end, it is connected to screens so that the doctor can see the images live. This exam permits the diagnosis of bladder anomalies such as polyps, bladder cancer, and malformations, but is also used to take swab samples called biopsies.
