Filter by:Objectives: Apply 3D- printed biomodels in patients with renal cancer (RCa) and vascular involvement (VTT) to: (1) improve surgical planning, (2) upgrade surgical results, (3) facilitate communication with patients, (4) serve as a model for teaching residents and (5) shortening the learning curve in experienced urologists. Methodology: The design of the study is a randomized clinical trial, to determine the safety, precision, feasibility, predictability, efficacy and efficiency of a surgical strategy based on imaging tests and 3D models regarding the surgical planning in patients with RCa and VTT. This is a longitudinal, prospective, experimental and multicenter study on a cohort diagnosed of RCa and VTT from 2018 in the Virgen del Rocío University Hospital (HUVR) or in the Ramón y Cajal University Hospital (HURC). The study will last for 3 years and will be carried out jointly by the HUVR, the HURC and the IBIS, in a multidisciplinary team made up of urologists, radiologists and engineers.
The purpose of this study is to compare the accuracy of measurements derived from a commercially available direct intra-oral scanning system with those taken from plaster study models, and to compare cost implications of both systems. The investigators will test the hypotheses: - There is no systematic difference between measurements taken from the Trios scanner and study models. - There is no difference in the cost of producing digital models.
