Student’s model aids kidney surgery training

A student has used 3D printing technology to create a model of a kidney that could be used to help train cancer surgeons.

The model created by Glasgow School of Art (GSA) student Lisa Ferrie could help surgeons hone their skills in performing a robot-assisted laparoscopic partial nephrectomy – a procedure that removes part of the kidney affected by a tumour.

This type of training in robotic surgery is currently provided by virtual reality simulators as well as cadaveric and animal models which are expensive and not widely available.

Miss Ferrie, a medical visualisation and human anatomy masters student at the School of Visualisation and Simulation, worked with medical experts to develop the model.

She said: “There is an increasing incidence of kidney cancer within the UK and where possible surgeons will use a procedure known as a partial nephrectomy to treat it.

“The procedure removes only the part of the kidney affected by the tumour, which is done to preserve as much kidney function as possible while still removing the cancer. This procedure is very technically challenging.

“I have a background in medical sciences and have developed a passion for improving medical education, clinical practice and patient care through the application of technology.

“The decision to focus on kidney cancer and the development of a surgical training model for robot-assisted laparoscopic partial nephrectomy was due to both my academic interest in the kidney and because the disease has personally affected my family.”

Starting with a CT scan from a patient who had kidney cancer, Miss Ferrie used 3D printing technology to develop and evaluate an anatomically accurate, low-cost surgical training model of a kidney with a tumour.

The 3D moulds are printed then filled with hydrogels capable of simulating human tissue.

Surgeons and trainees can then use the model to hone their skills.
