Cystoscopy (si-ˈstäs-kə-pē) is endoscopy of the urinary bladder via the urethra. It is carried out with a cystoscope.
There are two main types of cystoscopy—flexible and rigid—beeing different in the flexibility of the cystoscope. Flexible cystoscopy is carried out with local anaesthesia on both sexes. Typically, a topical anesthetic, most often xylocaine gel (common brand names are Anestacon and Instillagel) is employed. The medication is instilled into the urethra via the urinary meatus five to ten minutes prior to the beginning of the procedure. Rigid cystoscopy can be performed under the same conditions, but is generally carried out under general anaesthesia, particularly in male subjects, due to the pain caused by the probe.
