Global Assessments of the Endockscope System: Long-Term Impact of Cyber Endoscopy

The disproportionate costs of state-of-the-art endoscopic equipment prohibit urologists from performing endoscopy in underserved countries. Given the global prevalence of smartphones, we engineered a $45 alternative endoscope utilizing three-dimensional printed attachments, an 8 × lens, and a 1000-lumen light-emitting diode cordless flashlight (Endockscope System [ES]). At the 34th World Congress of Endourology in Cape Town, South Africa (WCE 2016; 4-year group), and at the 39th Congress of the Société Internationale d'Urologie (SIU) in Athens, Greece (SIU 2019; 8-month group), a total of 40 ES kits were distributed free of charge to an international group of urologists. Participants were given instructions and a hands-on demonstration of the device. Urologists given an ES were subsequently asked to complete a survey between June and September 2020 that included questions regarding user satisfaction, comfort, and comparability of the ES to standard endoscopic systems. Urologists from 23 countries received ES kits. Overall, 10 of 22 urologists (10/22; 45%) from the 4-year group and 18 of 18 urologists (18/18; 100%) from the 8-month group completed the survey. The ES device was used by 80% (8/10) and 83% (15/18) of urologists from the 4-year and the 8-month groups, respectively. Of note, the greatest impact of ES usage was among urologists from the most impoverished countries. Of those who used the ES, 44% (4/9) of urologists from the 4-year cohort and 47% (8/17) from the 8-month cohort reported they were able to perform more endoscopic procedures directly because of the ES. Moreover, 57% (4/7) of the 4-year participants and 67% (10/15) of the 8-month participants found the ES equal or superior in quality to their standard endoscopic equipment. The ES provided an effective and inexpensive system that enabled urologists in resource-challenged countries to effectively perform and expand their use of urologic endoscopy.
