Aspirin and the Risk of Microscopic Hematuria in Asymptomatic Screened Population

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.

Treatment and study plan

Primary outcomes

  1. Incidence rate of the microscopic hematuria

    Time frame: at the screening

    >4 RBC/HPF in urine microscopy

Secondary outcomes

  1. Detection rate of significant cause for microscopic hematuria

    Time frame: whitin 12 months after screening

    • 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
    • urinary stone
    • renal mass (benign or malignant / not simple cyst)
    • urothelial cancer
    • other lesions (clinically relevant lesions determined by researchers)

  2. Incidence rate of persistent microscopic hematuria

    Time frame: within 12 months

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