Prostate Volume & PSA Density

Prostate volume by the ellipsoid formula and, if a serum PSA is entered, the PSA density (PSA ÷ volume). PSA density ≥ 0.15 ng/mL/mL raises concern and is used in PI-RADS-based risk stratification.

Enter all values to calculate.

Formula

Volume = L × W × H × π/6. PSA density = serum PSA ÷ volume (ng/mL/mL). 1 mL ≈ 1 g.
