External validation of a post-operative renal function predictive model following partial nephrectomy

Key Points

• Evaluate the accuracy of a predictive model for post-operative renal function after partial nephrectomy.
• Applied the predictive model to clinical trial patients.
• Measured GFR using 99mTc-DTPA plasma clearance.
• Conducted validation across a population undergoing partial nephrectomy.
• The model performed well in predicting post-operative GFR.
• It can assist in counseling patients about expected renal function outcomes.
