Abstract
PURPOSE: Multimedia can be used to understand the basic anatomy and pathological features of the bladder, providing more intuitive knowledge than traditional education methods. Cystoscopy is one of the most fundamental and important diagnostic procedures for detecting pathology in the bladder. Thus, we developed a PC-based digitalized recording device and electronic document to create an electronic medical record to perform cystoscopy and used them for medical education.Entities:
