Surgical treatment involving the removal of the prostate may result in temporary or permanent erectile dysfunction (ED) and urinary incontinence (UI), with considerable impact on quality of life. Pelvic floor muscle training (PFMT) is one of the recommended techniques for the prevention, treatment, and rehabilitation of postoperative complications. The aim of this observational study was to assess the quality of YouTube videos\u2014accessible to any patient\u2014related to exercises after prostatectomy surgery. Methods: A systematic search was performed on YouTube on 24 September 2020. One hundred and fifty videos were selected and analyzed. Two statistical analyses were conducted based on machine-learning techniques, and videos were classified as \u2018Relevant\u2019 or \u2018Non-Relevant\u2019 using Principal Component Analysis (PCA) models. Two reviewers conducted independent analyses. Inter-observer agreement and individual correlations of video data were evaluated with the Intraclass Correlation Coefficient (ICC). Information quality, reliability, and accuracy were measured using the DISCERN Scale and Global Quality Score (GQS), while video popularity was evaluated using the Video Power Index (VPI). Results: DISCERN scored a mean of 3.35 and GQS scored 3.38. Average number of views was 124,354, mean duration was 14:42 min, mean days online was 1777, mean view ratio was 138.30, mean Likes was 1082, mean Dislikes was 68.58, and mean VPI was 92.28. Conclusions: The quality of the videos available on YouTube regarding the recommended pelvic floor exercises in PC surgery, according to the scores obtained, is High. Educational and health institutions, health professionals, government health authorities, and policy makers need to be involved in the proper development of policies to improve the information available on the web in order to have a positive impact on the healthy behavior of the population.<\/jats:p>","DOI":"10.3390\/jpm11090920","type":"journal-article","created":{"date-parts":[[2021,9,15]],"date-time":"2021-09-15T21:47:11Z","timestamp":1631742431000},"page":"920","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Quality Analysis of YouTube Videos Presenting Pelvic Floor Exercises after Prostatectomy Surgery"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4994-5825","authenticated-orcid":false,"given":"Alvaro","family":"Rodriguez-Rodriguez","sequence":"first","affiliation":[{"name":"Exercise Intervention for Health Research Group (EXINH-RG), Department of Physiotherapy, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5524-1587","authenticated-orcid":false,"given":"Maria","family":"Blanco-Diaz","sequence":"additional","affiliation":[{"name":"Physiotherapy and Translational Research Group (FINTRA-RG), Institute of Health Research of the Principality of Asturias (ISPA), Faculty of Medicine and Health Sciences, University of Oviedo, 33006 Oviedo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro","family":"Lopez-Diaz","sequence":"additional","affiliation":[{"name":"Physiotherapy and Translational Research Group (FINTRA-RG), Institute of Health Research of the Principality of Asturias (ISPA), Faculty of Medicine and Health Sciences, University of Oviedo, 33006 Oviedo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"de la Fuente-Costa","sequence":"additional","affiliation":[{"name":"Physiotherapy and Translational Research Group (FINTRA-RG), Institute of Health Research of the Principality of Asturias (ISPA), Faculty of Medicine and Health Sciences, University of Oviedo, 33006 Oviedo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Sousa-Fraguas","sequence":"additional","affiliation":[{"name":"Physiotherapy and Translational Research Group (FINTRA-RG), Institute of Health Research of the Principality of Asturias (ISPA), Faculty of Medicine and Health Sciences, University of Oviedo, 33006 Oviedo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8523-767X","authenticated-orcid":false,"given":"Isabel","family":"Escobio-Prieto","sequence":"additional","affiliation":[{"name":"Departamento de Fisioterapia, Facultad de Enfermer\u00eda, Fisioterapia y Podolog\u00eda, Universidad de Sevilla, 41009 Sevilla, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4391-960X","authenticated-orcid":false,"given":"Jose","family":"Casa\u00f1a","sequence":"additional","affiliation":[{"name":"Exercise Intervention for Health Research Group (EXINH-RG), Department of Physiotherapy, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,15]]},"reference":[{"key":"ref_1","unstructured":"The Global Cancer Observatory (2021, June 23).
