Side-by-side comparison helps you choose the right calculator for a specific clinical question.
Urology
Interpret post-void residual (PVR) volume for urinary retention and BPH evaluation. PVR <50 mL: normal. 50–200 mL: equivocal. >300 mL: significant retention requiring intervention.
Formula
PVR interpretation: Normal < 50 mL, Mild 50–99, Moderate 100–199, Significant 200–299, Severe ≥ 300 mL.
Inputs
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.
