10 Things to Know About Blood in Urine

Gross hematuria should be evaluated in everyone regardless of age or risk factors.

  1. Nationwide, less than 10% of hematuria patients are being referred for bladder cancer screening.
  2. Visible blood in urine is a common early sign of bladder and kidney cancers even if it only occurred once.
  3. 2-5% of patients with microscopic hematuria have bladder cancer with smokers and patients older than age 50 at highest risk.
  4. Close to 30% of people with visible blood in urine will have a urological diagnosis (10-30% cancer; >10% benign conditions such as bladder or kidney stones, etc).  Rates are higher in smokers and those who are older than age 40, and especially over age 60.
  5. Few #hematuria patients are being referred for #bladdercancer screening. #urology
  6. Full evaluation for hematuria requires: cystoscopy, CT Urogram with and without IV contract or equivalent study (MRI if cannot get CT) at a minimum.
  7. Close follow up is necessary for patients who do not have any abnormalities detected initially as there is increased risk for detection in the next 2 years.
  8. Blood in urine is frequently attributed to a UTI leading to late diagnosis of bladder cancer.
  9. Nephrological evaluation may be necessary in some patients.
  10. While the rates of malignancy are low in young patients with microscopic hematuria, nephrological problems may be identified.
