A CCafU-UroCCR Randomized Trial: 3D Image-Guided Robot-AssisTEd Partial Nephrectomy for Renal Complex Tumor (UroCCR N°99)

The goal of this clinical trial is to evaluate peri and post-operative outcomes as well as long-term survival of 3D IGRAPN compared to conventional Robot-Assisted Partial Nephrectomy (RAPN) for moderate and highly complex renal tumors. The main questions aim to answer: * peri-operative complications * oncological safety * long term renal function Participants will be asked to do undergo 3D-IGRAPN. Researchers will compare 3D-IGRAPN to RAPN to see if peri-operative outcomes are better in the experimental group.
