Multi-Institutional Analysis of Robot-Assisted Partial Nephrectomy for Renal Tumors >4 cm Versus ≤4 cm in 445 Consecutive Patients

Abstract

In the largest multi-institutional series of RPN for tumors >4 cm, we demonstrate safety, feasibility, and efficacy of RPN for tumors >4 cm. Patients with tumors >4 cm had a higher nephrometry score, longer WIT, and slightly higher estimated blood loss compared with patients who had tumors ≤ 4 cm, but there was no increased risk of adverse outcomes in the hands of experienced surgeons.
