Background
Urinary calculi formation is a common worldwide health problem. Six verities of renal calculi are known. The prevalence of urinary calculi and awareness of risk factors among the public in adult Egyptians are not addressed enough nowadays, so this study aims to assess the awareness of preventive measures for urinary stones among adult Egyptians.

Methods
Our study is a cross-sectional observational survey. This survey was elaborated through a link shared on social media. It was conducted for one month. The Egyptian adults who use social media and decided to join in the survey were incorporated using convenience and snowball samples (380 adults). A set of questions about urinary calculi and preventive measures were included in the survey to be answered. Statistical analysis was done using the Statistical Package for the Social Sciences (SPSS V20.0).
Results
Overall, 380 respondents participated in our survey. The prevalence of urinary calculi was 57 out of 380 (15%) of respondents. Multivariate analysis showed that a family history of stone formation and hypertension was significantly associated with the incidence of urinary calculi. The overall knowledge about preventive factors was poor in both groups stone former and other public groups with no statistical difference between the two groups regarding their awareness of preventive measures for urinary stone formation.
Conclusions
