Side-by-side comparison helps you choose the right calculator for a specific clinical question.
Urology
Calculate the International Prostate Symptom Score (IPSS/AUA-SI) to assess BPH symptom severity. Mild (0–7): watchful waiting. Moderate (8–19): medications. Severe (20–35): surgical evaluation.
Formula
Sum of 7 items (each 0–5). Total: 0–35. Mild ≤7, Moderate 8–19, Severe 20–35.
Inputs
Urology
Estimate prostate volume from TRUS or MRI measurements using the ellipsoid formula (π/6 × L × W × H). Normal prostate is 20–30 mL; volume >40 mL suggests clinically significant BPH.
Formula
V = W × H × L × π/6 ≈ W × H × L × 0.523 (cm → mL)
