Using 3D Kidney Model Based on Artificial Intelligence to Assist Partial Nephrectomy: A Prospective Validation Study

This study is testing whether a 3D kidney model created by artificial intelligence (AI) using CT or MRI images can help surgeons perform more precise, minimally invasive kidney surgery (partial nephrectomy) for kidney tumors. **You may be eligible if...** - You are between 18 and 80 years old - You have a kidney tumor (stage T1a or select T1b) confirmed by imaging that is suitable for partial removal - Your tumor is localized with no spread to lymph nodes or other organs - You are scheduled for laparoscopic or robotic kidney surgery **You may NOT be eligible if...** - You have tumors in both kidneys or multiple tumors in one kidney - You have received targeted cancer therapy, immunotherapy, or chemotherapy in the past 6 months - You have severe surgical risks (e.g., significant bleeding disorders) Talk to your doctor to see if this trial is right for you.
