Our aim is to determine if surgery planning based on 3D models in comparison with the conventional surgery planning, allows a more predictable surgery. METHODS: Multicenter clinical trial on 66 patients diagnosed with RCC and TTV who underwent a nephrectomy with thrombectomy. Patients were randomized 1:1 to the 2 study groups: 1) surgery planning with conventional images; 2) surgery planning with 3D models. Each urologist answered a questionnaire before and after the surgery and a Kappa index was used to measure the agreement between surgery planning and the surgery itself in the two study groups. RESULTS: See Table. CONCLUSIONS: Surgery planning with 3D models was more predictive than surgery planning with conventional images in RCC with VTE.
