What are the chances of someone with macroscopic haematuria having bladder cancer?
The prevalence of microscopic haematuria is 0.19–21.0%. Macroscopic haematuria is more concerning and warrants thorough investigation, as the prevalence of urinary tract carcinomas among patients with macroscopic haematuria has been reported to be as high as 19%, but usually ranges from 3–6%.

What is the prevalence of haematuria in patients with bladder cancer?
The PPV of visible haematuria for bladder cancer was considerably lower in the new analysis: 2.8% (95% CI = 2.5 to 3.1) instead of 3.9% (95% CI = 3.4 to 4.4) for those aged ≥60 years. Similarly, in the group aged 40–59 years, the PPV for visible haematuria fell from 3.1% (95% CI = 1.0 to 9.8) to 1.2% (95% CI = 0.6 to 2.3).
