Background: With webinars looking to be the mainstay post-pandemic, it is important to demonstrate whether webinars are, indeed, effective educational tools for professional training and skill acquisition. We aim at demonstrating, via a global survey, the efficacy of webinars on percutaneous nephrolithotomy (PCNL) and how this knowledge transforms clinical practice. Methods: A structured online survey covering the following sections: (1) Demographics, (2) PCNL techniques, and (3) PCNL equipment was circulated. The target study population were practicing urologists and residents. Categorical data were presented with counts and percentages, and they were compared by using Chi-square test. Continuous data were analyzed with non-parametric methods. Respondents were dichotomized according to attendance of webinar type, attendees of dedicated PCNL webinars (Group A), or attendees of endourological webinars that discussed some aspects of PCNL (Group B). Results: A total of 303 respondents from 38 countries participated. Overall, 91.7% (n = 278) were in Group A and 8.3% (n = 25) were in Group B; 77.9% were younger than 50 years, whereas 51.8% had more than 10 years of urology experience. In group A, urologists of all ages, in academic institutions and private practitioners, significantly benefited in gaining knowledge about the merits of newer devices and the role of suction-assisted devices in modern PCNL. The majority of group A also reflected that by attending a dedicated PCNL-based webinar they benefited in learning newer positions for PCNL access, especially supine, and how to effectively use laser as energy devices for lithotripsy. In Group B, the only area of benefit was in lasing techniques and the use of newer lasers such as the thulium fibre laser. Conclusion: Our survey positively validates the two proposed hypothesis, that is, webinars as a medium of education do benefit practicing urologists in knowledge and the clinical practice domains. Age, experience, or place of practice is no barrier to adopting newer mediums of education such as webinars. [ABSTRACT FROM AUTHOR]
