French Hospital 3D Prints Multi-Materialized Kidney Models for Cancer Surgery

One of the most innovative ways that 3D printing technology has been used in the medical field thus far is surgery preparation, which has become much easier to plan thanks to personalized 3D models of certain inner workings of the human body. Utilizing a Stratasys Objet500 Connex3, the Department of Urology and Kidney Transplantation at the University Hospital (CHU) de Bordeaux, which is located in France, was able to print out multi-materialized and specifically colored kidney models. According to CHU, they are the first hospital in France to utilize Stratasys’ 3D printing technology to plan for intricate tumor removals within the kidney.

Having a 3D printed model comprising the patient’s kidney tumor, main arteries and vessels – each in a different color – provides an accurate picture of what we will see during operations,” says Dr Jean-Christophe Bernhard, a CHU surgeon. “Importantly, the ability to visualize the specific location of a tumor in relation to these other elements, all in three dimensions, greatly facilitates our task and is not something that is easily achievable from a 2D scan.”

By planning on an accurate kidney model, detailed down to the very last artery and blood vessel, surgeons at CHU are able to practice these complex tumor removals to ensure that no damage is done to this delicate human organ.Read more
