Introduction & Objective : We evaluated the association of the Mayo Adhesive Probability (MAP) score and robotic assisted partial nephrectomy (RAPN) outcomes. The MAP score is described as an Accurate Image-based Scoring System to Predict Adherent Perinephric Fat in Partial Nephrectomy.


Methods : We retrospectively analyzed 75 patients who had RAPN performed by a single surgeon between May 2016 and March 2018.Our analysis focused on comparing perioperative outcomes, including operative time, warm ischemia time, operative time other than warm ischemia time, estimated blood loss and postoperative complications with MAP score and RENAL score. We categorized Patients into “low” (0 to 3) or “high” (4 or 5) score groups based on MAP score. We also categorized Patients into low (4 to 6) or moderate – high (7 to 10) complexity groups based on RENAL nephrectomy score.


Results :

The operative time was longer in high MAP score group than in low MAP score group (197 vs 174 min, p=0.018). The operative time other than warm ischemia time was longer in high MAP score than in low MAP score (177 vs 155 min, p=0.010).The warm ischemia time, estimated blood loss and postoperative complications were similar between both groups of MAP score.The warm ischemia time was longer in moderate - high complexity groups than in low complexity groups of RENAL nephrectomy score (20.2 vs 15.8 min, p=0.027). The operative time, operative time other than warm ischemia time, estimated blood loss and postoperative complications were similar both groups of RENAL nephrectomy score.


Conclusions : A higher MAP score was associated with longer operative time, and especially longer operative time other than warm ischemia time. A higher RENAL nephrectomy score was associated with longer warm ischemia time.
