Aspirin and the Risk of Microscopic Hematuria in Asymptomatic Screened Population
- Conditions
- Asymptomatic General PopulationMicroscopic Hematuria
- Registration Number
- NCT01615315
- Lead Sponsor
- Seoul National University Hospital
- 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.
