ClinicalTrials.gov Identifier:
NCT01615315
First received: June 6, 2012
Last updated: August 27, 2012
Last verified: August 2012
  Purpose

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.


Condition
Asymptomatic General Population
Microscopic Hematuria

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Retrospective

Further study details as provided by Seoul National University Hospital:

Primary Outcome Measures:
  • Incidence rate of the microscopic hematuria [ Time Frame: at the screening ] [ Designated as safety issue: No ]
    >4 RBC/HPF in urine microscopy


Secondary Outcome Measures:
  • Detection rate of significant cause for microscopic hematuria [ Time Frame: whitin 12 months after screening ] [ Designated as safety issue: No ]
    • 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)

  • Incidence rate of persistent microscopic hematuria [ Time Frame: within 12 months ] [ Designated as safety issue: No ]
    • Among participants who had microscopic hematuria at the screening
    • Determined by repeated urine microscopy
