Purpose: To report our initial experience using a patient-specifi c 3D-printed renal tumor model for the surgical planning of a complex heminephrectomy in a horseshoe kidney.
Materials and Methods: We selected a clinical case for a complex laparoscopic surgery consisting in a 53 year-old male presenting a local recurrence of a renal tumor in a horseshoe kidney with aberrant vascularisation previously treated with a laparoscopic partial nephrectomy. He is now proposed for a laparoscopic left heminephrectomy.
Along with conventional imaging, a real-size 3D-printed renal model was used to plan de surgical approach. The perioperative experience of the surgical team was recorded.
Results: The surgical team found the patient-specifi c 3D printed model useful for a better understanding of the anatomy and an easier surgical planning.
Conclusion: The use of patient-specifi c 3D-printed renal models seem to be helpful for the surgical planning in complex renal tumors.
