The ability to photograph the interior of the bladder accurately just by pressing a button has great clinical merit. This approach, which has become a basic method in gastrointestinal endoscopy, is now possible in cystoscopy. We will call this technique which uses a newly designed telescope, Olympus A 3405 and Polaroid Instant Endocamera EC-3 with Polaroid High Speed Color Land Film 600, photocystoscopy . The telescope used in photocystoscopy has more improved resolution and homogeneous brightness through its field of view than the conventional telescope, Olympus O 3405. The photographic image of the bladder interior taken by the Polaroid camera has a good color and fine resolution but its size which is 2.5 cm in diameter is too small for clinical use. Color instantographs by the Polaroid camera are most appropriate for use in photocystoscopy , but many devices and improvements are necessary before it can be used routinely.
