669 3D virtual model for robot-assisted partial nephrectomy in complex hilar renal tumors

Dr. Swapnil Singh Kushwaha

Problem- Managing complex hilar renal tumors during robot-assisted partial nephrectomy (RAPN) is technically challenging due to difficult anatomy, proximity to major vessels, and the risk of excessive bleeding or incomplete tumor removal. Traditional planning based on 2D CT images often lacks depth perception and spatial clarity, increasing operative time and complications. Solution – A 3D virtual model (3DVM) reconstructed from 2D CT images offers a detailed anatomical roadmap. This allows surgeons to preoperatively plan vascular control, anticipate anatomical variations, and perform targeted dissection during RAPN. Innovation – The innovation lies in transforming standard imaging into a 3D model, enhancing surgical precision. Our study shows that 3DVM significantly reduces console time and blood loss. However, while it aids visualization, it does not significantly impact warm ischemia time, oncological or functional outcomes, prompting careful evaluation of its routine use in complex hilar cases, whenever global ischemia is used.
