Background: YouTube, as a widely used video website around the world, contains a large number of surgical teaching videos, providing a good platform for doctors to learn surgery, but its content and quality are uneven. Tension-free vaginal tape obturator (TVT-O) and trans-obturator vaginal tape (TOT) are common surgical methods for the treatment of stress urinary incontinence (SUI), and there are many videos on YouTube teaching these procedures. We aimed to assess the educational value of surgical videos of TVT-O and TOT on YouTube.Methods: A comprehensive search was conducted for "tension-free vaginal tape obturator" and "transobturator vaginal tape" on YouTube on August 22. After referring to LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) and previous studies, we developed a checklist containing 5 major items and 18 minor items. SPSS 26 was applied to data and correlation analysis.Results: A total of 36 videos were assessed. The average number of days available was 1,956.6 days (range, 190-4,152 days) and the average length was 9.7 min (range, 1.8-73.6 min, SD: 13.65). Video definition is divided into high, moderate and low, accounting for 22%, 36% and 42% respectively. The average score of the included videos was 7.39 (range,(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) SD: 3.57). The correlation analysis indicated that the video quality score has a certain correlation with the length of the video, but has no significant correlation with other factors and there was no significant correlation between audience likes and other factors.Conclusions: On YouTube, we still lack high educational value videos about TVT-O and TOT, and the existing videos are deficient in the explanation of critical steps, the key points of patients' perioperative management, and the application of auxiliary teaching tools. This further indicates the importance of improving educational videos of surgery, and an authoritative checklist for urologic surgery.

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.
