MP48-01 PSEUDOCAPSULE INFILTRATION, POSITIVE SURGICAL MARGINS AND LOCAL RECURRENCE AFTER ENUCLEATIVE ROBOT-ASSISTED PARTIAL NEPHRECTOMY (RAPN) FOR RENAL CELL CARCINOMA (RCC): RESULTS AT A MEDIAN FOLLOW-UP OF 56 MONTHS

In our series, tumor histology and pT stage were the strongest predictors of PC invasion after enucleative RAPN. However, neither PC invasion nor positive margins were associated with local recurrence within the enucleation bed, confirming the oncologic safety of this technique. Further studies are needed to validate our results assessing the prognostic role of PC invasion for different resection techniques.
