Objective: To assess the quality and readability of online information on holmium laser enucleation of the prostate in managing benign prostate hyperplasia using the most-used search engine worldwide, Google. Methods: Google search terms “Holmium laser surgery” and “enlarged prostate” were used to generate 150 search results. Two independent authors (i) excluded any paywall, scientific literature, or advertisement and (ii) conducted an independent assessment on information quality, which was based on DISCERN, QUEST, and JAMA criteria, and readability, which was based on the FKG, GFI, SMOG, and FRE scores on qualified webpages. A third author was involved if there were any discrepancies between the assessments. Results: 107 qualified webpages were included in the data analysis. The median DISCERN score was 42 out of 80 (IQR 35–49). The median JAMA score was 0 out of 4 (IQR 0–1). The median QUEST score was 9 out of 28 (IQR 9–12). Using the non-parametric ANOVA and post hoc Games–Howell test, significant differences were identified between rankings of webpages. Sponsorship had no influence on the quality of webpages. The overall readability level required a minimum reading level of grade 11. Linear regression analysis showed that a higher ranked webpage is a positive predictor for all three quality assessment tools. Conclusions: The overall quality of online information on HoLEP is poor. We identify that the top-ranked google searches have a higher DISCERN score and are a positive predictor for DISCERN/QUEST/JAMA. Quality online information can benefit patients but should be used in conjunction with professional medical consultation.
