Asymptomatic General Population, Microscopic Hematuria
Conditions
Keywords
aspirin, screening, microscopic hematuria
Brief summary
Aspirin can increase the risk of bleeding tendency. However, correlation between aspirin treatment and hematuria in general population is not well known. The investigators will evaluate whether daily use of aspirin increase the risk of microscopic hematuria in healthy large screened populations.
