Neocapsular reconstruction for challenging partial nephrectomy: A feasibility study in a porcine model and recent clinical experience.

Objectives: Multifocal renal masses and large central-endophytic tumors can be challenging for partial nephrectomy (PN) due to the paucity of capsule remaining after tumor removal. Our objective was to develop a neocapsule to provide tamponade and test its feasibility/safety in a porcine model.

Methods: Eight live pigs (50-70 kg) underwent unclamped open right flank PN.
