Rein 3D PRINT MECHANICS

Multimodal Imaging of the Biomechanical Properties of Kidney Tumors: Feasibility, Inter-modality Correspondence and Diagnostic Value

Sponsor

University Hospital, Bordeaux

Enrollment

50 participants

Start Date

Mar 7, 2025

Study Type

INTERVENTIONAL

Conditions

Kidney Cancer

Summary

The goal of this innovative project is to evaluate the correspondence between several imaging modalities for characterizing the elasticity of healthy and pathological renal tissue which could help improve the realism of 3D prints used by urological surgeons and allow the identification of new, complementary imaging biomarkers. The main objective is to develop a predictive model of the biomechanical properties of normal and pathological kidney tissue, as assessed by the reference method (Magnetic Resonance (MR)-elastography).

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study is creating detailed 3D-printed physical models of patients' kidneys and kidney tumors before surgery. The aim is to understand the biomechanical properties (how firm or stiff) of kidney tissue and tumors, which may help surgeons better plan and perform kidney operations more precisely. **You may be eligible if...** - You are 18 or older - You are scheduled for kidney surgery (nephrectomy) to remove a kidney tumor at Bordeaux University Hospital - A CT scan is available or planned for surgery - You have consented to be included in the UroCCR database **You may NOT be eligible if...** - You are pregnant or breastfeeding - You have a contraindication to MRI or to gadolinium (MRI contrast dye) - You have had a biopsy before the imaging studies for this study - You have spinal implants in your lower back - Your BMI is 30 or above - Your kidney tumor is cystic or necrotic with a small solid component (under 2 cm) - You have ascites (fluid buildup in the abdomen) - You speak French at an insufficient level Talk to your doctor to see if this trial is right for you.
