3D image-guided robot-assisted surgery for complex kidney tumors

A CCafU-UroCCR Randomized Trial: 3D Image-Guided Robot-AssisTEd Partial Nephrectomy for Renal Complex Tumor (UroCCR N°99)

NA · University Hospital, Grenoble · NCT05572216

This study is testing a new robot-assisted surgery technique for complex kidney tumors to see if it leads to fewer complications and better long-term kidney function compared to the standard method.

What this trial studies

This clinical trial evaluates the outcomes of a new surgical technique called 3D Image-Guided Robot-Assisted Partial Nephrectomy (3D IG-RAPN) compared to the conventional Robot-Assisted Partial Nephrectomy (RAPN) for patients with moderate to highly complex renal tumors. The study aims to assess peri-operative complications, oncological safety, and long-term renal function preservation. Participants will undergo the experimental procedure, and researchers will analyze the results to determine if the new approach offers better outcomes. The trial will be conducted across 12 high-volume urological centers within the UroCCR Network.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with moderate or high complexity renal tumors who are eligible for robot-assisted surgery.

Not a fit: Patients with medical contraindications to robot-assisted surgery or those with renal insufficiency that prevents iodine injection may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved surgical outcomes and long-term health for patients with complex renal tumors.

How similar studies have performed: While the use of augmented reality in surgery is an emerging field, this specific approach has not been widely tested, making it a novel investigation.
