RENAL Nephrometry Score

Standardised scoring of renal tumour anatomy for surgical planning. Predicts operative complexity and guides decision between partial and radical nephrectomy.

This is a descriptive suffix (not scored), but affects surgical planning. Note: 'a', 'p', or 'x' appended to score.

Score interpretation

Low Complexity 4–6

RENAL Score 4–6 — low complexity tumour

→ Partial nephrectomy (nephron-sparing) strongly preferred; suitable for laparoscopic or robotic approach; low risk of major complications

Moderate Complexity 7–9

RENAL Score 7–9 — moderate complexity tumour

→ Partial nephrectomy feasible; higher risk of perioperative complications; experienced surgeon required; open approach may be preferred

High Complexity 10–12

RENAL Score 10–12 — high complexity tumour

→ Radical nephrectomy often needed; partial nephrectomy possible in experienced centres; discuss risk of warm ischaemia time and blood loss; tertiary urology centre referral

Interpretation bands for the RENAL Score. Apply clinical judgement and local guidance.
