About half of them had experienced renal stones either personally or in a direct family member. 91.4% of them are aware that increased water intake decreases the formation of renal stones. As for symptoms of urinary stones, 65.36% of them thought that pain and other urinary symptoms would occur when having urinary stones. Radiology imaging was the most chosen mode of diagnosing urinary tract stones especially amongst participants above the age of 35 (p-value= 0.002) with surgical intervention as the best treatment according to the participants. 57.2% of the participants believe that drinking parsley water prevents the formation of renal stones. Individuals who experienced renal stones before were more knowledgeable about the commonest type of renal stones (p-value= 0.005) and the quantity of recommended daily fluid intake (p-value= 0.008). Conclusion and Recommendation: this data indicates that the participants are to some degree aware of some aspects of renal stone prevention, symptoms and modes of diagnosis and treatment.
