3D Urology: Mini-invasive partial nephrectomy with biomodels

Dr. Francisco Telayna Manrique, Dr. José Ignacio Acuña Madrid & Dr. Mario Hassi

Hospital Felix Bulnes - Santiago de Chile, Chile


An understanding of anatomy that goes beyond the anatomy

Simplification of the surgical plan

Clear doctor-patient interaction

3D guidance in the operating theatre

Improved communication between the surgical team

Clincal case

In this clinical case, a 56-year-old male patient with a left renal tumour was treated.

We sought to resect the tumour laparoscopically.

3D anatomical model

FDM Technology

Material: PLA

Resolution: 0.2 mm

Finish: Multiple color

Surgical plan and results in operating room

For tumour resection, a left transperitoneal laparoscopic partial nephrectomy was performed with the installation of 4 trocars.

A 3D biomodel was generated to help design the most appropriate surgical plan. It also allowed the creation of an experimental model to practice the surgery on its simulator.

The anatomical model was also used to explain to the patient and his family about the existing pathology and the surgical procedure to be performed.

In the operating room, the physical and virtual 3D models were used to guide the surgical approach. Ischaemia time was only 20 minutes with a total surgery time of 2:55 hours and an estimated bleeding of 600 ml.

Dr. Telayna refers to 3D technology as: "excellent for planning surgery, pre-operating surgery and excellent for doctor-patient interaction".
