Clinical case

A tomographic control was performed in a 37-year-old female patient with no history of disease. The results showed a renal incidentaloma in the right kidney.

The complexity of the case lay in the fact that the tumour was located completely within the renal parenchyma with no external visualisation. This represented a significant compromise of the structure and functionality of the kidney.

Surgical plan and results in operating room

The surgical plan was a laparoscopic partial nephrectomy with a transperitoneal approach, designed using a digital model of the organ and structures of interest.

It was of utmost importance to be able to determine the extent of the tumour and precisely identify its relationship with the rest of the renal anatomy, in order to achieve a resection with optimal negative margins and favour the performance of renal function post-surgery.

The 3D biomodelling allowed the procedure to be performed in just 2 hours, with less bleeding and greater control due to the predictability of the surgical scenario.
