Foot switch photography with a lecture scope in cystourethroscopy.

Photography during cystourethroscopy has been made lighter and easier with a new system involving a special lecture scope and a 16 mm. camera. With this system endoscopic photographs can be made by pushing a foot pedal. Therefore, the system allows for free movement and full control of the cystourethroscope. Bright and sharp photographs are produced, making them useful in the diagnosis of a case. In addition, the same view can be observed by an operator and an assistant simultaneously.
