    RENAL Nephrometry Score

    Categorizes renal masses by complexity for surgical decision-making.
    Favorite

    BEFORE USE

    Use cross-sectional imaging (CT or MRI, not ultrasound).

    Advice

    Consider competing risks of morbidity and mortality, oncologic prognosis, and patient preference to inform decision-making and to risk-stratify management strategies.

    Management

    Management of small renal masses:

    • Management strategies typically include:
      1. Surgical intervention.
        • Partial nephrectomy (PN).
          • Minimally invasive surgery (MIS) vs. open surgery.
        • Radical nephrectomy (RN).
          • MIS vs. open.
      2. Ablative intervention.
        • Cryoablation.
        • Radiofrequency ablation.
      3. Active surveillance (structured expectant management)
    • Impact of RENAL score on surgical decision-making:
      1. PN vs. RN: Higher complexity score more likely to undergo RN.
      2. MIS vs. open: High complexity scores more likely to undergo open surgical approaches.
      3. Active surveillance vs. intervention: High complexity score more likely to undergo surgical intervention.

    Critical Actions

    Not to be used with ultrasound imaging—requires cross-sectional imaging (i.e., CT or MRI).
