Benefits
✔ Superior understanding of the tumour and its environment
✔ Improved surgical plan design
✔ Real-time operating room guidance
✔ Reduced operating time
Clinical case
A 43-year-old male patient, with no history of disease, is diagnosed with renal cortical tumour in the left kidney.
Custom 3D Biomodels
To plan the patient's surgery, three models were made to clearly identify each of the anatomical structures:
3D model of the entire kidney
3D model of the urinary tract with tumour
3D model of the arterial network with the tumour
Characteristics of the biomodels:
â—¾ FDM technology - Material: PLA
â—¾ Resolution: 0.2 mm - Finishing: Multiple colours
Surgical plan design and outcomes
In uro-oncology, the use of 3D models provides very important benefits such as reduced ischaemia time and less bleeding (Fan et al., 2019).
In this regard, Dr Richards, who has extensive experience in the implementation of 3D technology, routinely uses it on highly complex patients.
On this occasion, to plan the customised surgery, Dr Richards used the virtual biomodel and three full-scale physical models.
The surgical plan chosen was a laparoscopic left partial nephrectomy.
Thanks to a thorough understanding of the case and detailed planning, the surgery was successfully performed in 90 minutes.
"3D models make surgery faster, more efficient and safer. In selected patients I think it should be a new standard", Dr Richards explains.
