Munich, Germany (UroToday.com) RENAL score is used to predict the technical and anatomical complexity of a renal tumor. Mayo Adhesive Probability (MAP) is a radiographic score that have been shown to predict the presence of adherent perirenal fat (APF). The group from France investigated the ability of MAP and RENAL scores for predicting perioperative morbidity after robot-assisted partial nephrectomy (RAPN).
The group analyzed 242 patients who underwent RAPN and measured the MAP and RENAL scores prospectively. The demographic and surgical data was obtained from chart review.
In their analysis, MAP score was found to be associated with high risk of conversion to open surgery (OR 4.1, 95% CI 1.7-8.8) and transfusion (OR 2.9, 95% CI 2-4.1). However, RENAL score was not a predictor for either conversion to open surgery (OR 2.7, 95% CI 0.4-6.3) or transfusion (OR 1.7, 95% CI 0.7-2.4). Both RENAL and MAP Scores was predictive of EBL. Both MAP score (OR 6.1, 95% CI 1.9-9.8) and RENAL score (OR 11.4, 95% CI 2.1-19.4) were also associated with higher risk of conversion to radical nephrectomy.
The group concludes that the MAP score adds additional prognostic information than RENAL score and may allow better prediction of perioperative morbidity of RAPN than the RENAL score alone.
