Seasonal Variation of Public Interest in Urinary Tract Infections and Kidney Stones: A Google Trends Analysis

Background: Kidney stones and urinary tract infections (UTIs) are two of the most common urologic conditions, both of which have been shown to exhibit seasonal patterns in incidence with higher rates during warmer months. Understanding public engagement with these conditions, especially through online search behavior, may offer insight into when interest, awareness, or symptom occurrence is most likely to rise. Objective: The objective of this study is to evaluate seasonal variation in public interest for kidney stones and urinary tract infections using Google Trends data from 2004 to 2023. Methodology: Monthly Google Trends data (2004–2023) were collected for the search terms “kidney stones,” “urinary tract infection,” and “UTI” within the United States. Search Volume Index (SVI) values (0–100 scale) were averaged by calendar month to assess seasonal trends. The highest monthly SVI for each term in the 20-year period was set to 100, with all other values scaled proportionally. Results: Public interest peaked in July for “kidney stones” (average SVI 60.3), “UTI” (abbreviation, average SVI 54.2), and “urinary tract infection” (average SVI 71.2). All three search terms showed elevated interest from late spring through summer, with the lowest interest observed during the winter months. Conclusion: Public interest in kidney stones and UTIs demonstrates clear seasonal variation, peaking during the summer months. These patterns suggest that digital search behavior may reflect underlying seasonal shifts in disease awareness or incidence. Leveraging this information could improve the timing of public health education and resource allocation for these urologic conditions.
