Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adult patients scheduled for laparoscopic partial nephrectomy due to a unilateral kidney tumor.
✕Probably not a fit
Patients who do not speak or understand French or those without a preoperative CT scan for modeling may not benefit from this study.

What this trial studies
This clinical trial evaluates the impact of personalized three-dimensional models of patients' tumoral kidneys on pre-operative anxiety before nephron-sparing surgery. Patients will be randomly assigned to one of three groups: one receiving a 3D virtual model, another with a 3D printed model, and a control group receiving standard information. The primary outcome measure is the change in anxiety levels assessed using the STAI state score. The study aims to enhance patient understanding and satisfaction while addressing the psychological impact of surgery.
Why it matters
Potential benefit: If successful, this approach could significantly reduce pre-operative anxiety for patients undergoing kidney surgery.
How similar studies have gone: While there is evidence supporting the use of 3D modeling in surgical planning, this specific approach to reducing anxiety has not been extensively tested.
