泌尿器科内視鏡におけるビデオシステムの応用

Abstract

The possibility of many persons viewing the same field together has been long desired in urological endoscopy, not only for objective diagnosis and proper treatment but also as an aid in teaching. Since 1978, the authors have been using the video-system consisting of an MK- 309C as a video-camera with a television monitor, the connecting scope between the endoscope and the video-camera, and a CLX as a light source. This system has been used in cystourethroscopy, TUR and fiberscopy of the upper urinary tract by our pyeloureteroscope . The features of this system are to use the connecting scope which allows television monitoring of the findings without disturbing the handling of the endoscope by the operator, the three-tube video-camera which transmits the pictures in quite natural color and good resolution to the television monitor and the very bright light source which gives clear views of the lesions. The endoscopic field that could be viewed simultaneously by many persons using this system proved to be satisfactory.
