Aspirin and the Risk of Microscopic Hematuria in Asymptomatic Screened Population

Seoul National University Hospital60,048 enrolled

Overview

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.

Outcomes

Primary Outcomes

Incidence rate of the microscopic hematuria

\>4 RBC/HPF in urine microscopy

Time frame: at the screening

Secondary Outcomes

Detection rate of significant cause for microscopic hematuria

* Among participants who had microscopic hematuria at the screening * By imaging study or cystoscopy * At the screening or within 12 months after screening * Significant cause for microscopic hematuria 1. urinary stone 2. renal mass (benign or malignant / not simple cyst) 3. urothelial cancer 4. other lesions (clinically relevant lesions determined by researchers)

Time frame: whitin 12 months after screening

Incidence rate of persistent microscopic hematuria

* Among participants who had microscopic hematuria at the screening * Determined by repeated urine microscopy

Time frame: within 12 months
