AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with a kidney tumor who are scheduled for robot-assisted partial kidney removal surgery. It tests whether seeing a 3D model of their kidney lowers anxiety before surgery.

Age
18 years or older
Sex
All sexes can join.
Disease stage
Kidney tumor on one side, or a first surgery for tumors on both sides. Surgery planned is laparoscopic partial nephrectomy with robotic assistance.

Main reasons for not taking part

  • Refusing consent or participation
  • Difficulty understanding and speaking French
  • Being under guardianship or curatorship
  • No CT scan from before surgery available for the 3D model

About the trial

What the trial wants to find out

The goal of this clinical trial is to evaluate the impact of showing and handling a three-dimensional modelization of a patient's tumoral kidney the day before his nephron-sparing surgery. The main outcome measure was the effect on anxiety assessed via the STAI state score. 3 types of pre-operative information were compared (3D virtual model, 3D printed model, and information) using a randomization.

The 3 groups in the trial

  • Virtual 3D model groupExisting treatment, for comparison

    exchange time with the virtual 3D model of the kidney to be operated on as information support

    Treatment: 3D model pré-operative education

  • 3D Printed Model GroupExisting treatment, for comparison

    eexchange time with the printed three-dimensional model of the kidney to be operated on as information support

    Treatment: 3D model pré-operative education

  • Control groupNo study treatment, for comparison

    discussion time with the patient information sheet of the French Association of Urology (AFU) as information support

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
