Our objective is to obtain a feasible and accurate 3D virtual image and to evaluate surgeons feedback when using this technology for surgery planning.

A specific protocol was developed to obtain a computed tomography (CT) image: early arterial and nephrogenic phase. ITK-snap ® and VirSSPA Software ® (developed in our center) were used to segment the areas of interest. The resulting 3D mesh was processed with MeshMixer ® and Cura ®. Some measures were taken in the CT and the 3D image to evaluate the accuracy (less than 1mm of difference).

The surgery planning was made using the CT and the 3D virtual image, and the surgery was performed afterwards. 6 expert urologists from two different hospitals were asked to answer a validated satisfaction questionnaire (doi: 10.1093/ejcts/ezx208).

All the measurements taken in the 3D virtual image had less than 1mm desviation from CT

The cost of the 3D virtual reconstruction was 200€

The time to obtain the 3D virtual image was 12h.

100% of urologist thought that the 3D image was very useful for surgery planning and that was complementary to the conventional images, offering a better understanding of the problem. All of them would recommend the model to other colleges
