Educational value assessment of YouTube surgical videos of green light laser vaporization of the prostate.

Background: YouTube is commonly used by doctors to learn surgery. To date, no studies have evaluated the quality of videos on photoselective vaporization of the prostate (PVP) for benign prostatic hyperplasia (BPH) on YouTube. Our aim was to assess the educational value of YouTube videos regarding PVP. Methods: "Green light laser vaporization of the prostate" and "photoselective vaporization of the prostate (PVP)" were searched by 2 authors on YouTube on February 14, 2022. Based on the Laparoscopic Surgery Video Educational Guidelines and previous studies, a checklist that included 4 major and 16 minor items was developed. SPSS version 26 (IBM Corp., Armonk, NY, USA) was used to analyze the data using correlation analysis. Results: A total of 74 surgical videos were assessed. The mean number of days available for educational videos was 2,607 days (range, 156-5,854 days), with the earliest videos dating back to 2006 and the latest to 2021. The average length was 12.69 minutes (range, 0.73-123.7, SD 21.25). The majority of videos originated in the United States, and the video definition was divided into high, moderate, and low, accounting for 21.6%, 66.2%, and 12.2% of the videos, respectively. The average numbers of likes and dislikes for videos were 34.26 (SD 87.96) and 0, respectively. The average score of the videos was 6.65 (range, 2-12, SD 2.79). The correlation analysis indicated that the number of views of these videos was related to the number of online days and likes. The scores of videos were related to the number of likes, and the annual average number of views was related to both the number of views and the number of surgeon likes. Conclusions: There is a lack of high-quality surgical videos of green laser vaporization of the prostate on YouTube. More detailed explanations of the key steps of the operation are needed. We hope that more videos with higher educational value will be published in the future to help surgeons master this technology.
