Tumor-parenchyma interface and long-term oncologic outcomes after robotic tumor enucleation for sporadic renal cell carcinoma.

•Evidence on long-term oncologic outcomes after robotic tumor enucleation (RTE) is lacking.•Retrospective, single-center study on 121 RTEs for sporadic renal cell carcinoma.•A distinct peritumoral pseudocapsule was present in 95% of tumors.•Complete pseudocapsule invasion was reported in 19.8% of cases.•Predictors of complete pseudocapsule invasion were tumor diameter, endophytic rate, and papillary histology.•At a median follow-up of 61 months, no cases of tumor recurrence at the enucleation site were reported.
