Impact of Renal Hilar Control on Outcomes of Robotic Partial Nephrectomy: Systematic Review and Cumulative Meta-analysis

Off-clamp, selective clamp, and early-unclamping hilar control techniques are safe and feasible approaches to robotic partial nephrectomy, with similar transfusion rates, complications, and oncological outcomes compared with on-clamp robotic partial nephrectomy. Careful patient selection, robotic expertise to maximize vascularized remnant parenchymal volume, and complication-free recovery are the paramount considerations.
