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

Who May Qualify: - Ages 18-80 years, regardless of gender - Written willing to sign a consent form obtained from the patient or legally authorized representative after full protocol disclosure - Preoperative imaging (CT/MRI) confirming clinical stage T1a or select T1b renal tumors suitable for partial nephrectomy (R.E.N.A.L. nephrometry score ≤10) - Localized renal tumors without lymph node/distant metastasis per NCCN Guidelines® (v2023) - Elective minimally invasive partial nephrectomy (laparoscopic/robotic) after comprehensive surgical counseling Who Should NOT Join This Trial: - Multifocal renal tumors (bilateral or unilateral) - Prior systemic anticancer therapy (targeted agents/immunotherapy/chemotherapy) within 6 months - Absolute surgical contraindications (e.g., ASA class ≥IV, uncontrolled coagulopathy) - Intraoperative conversion to radical nephrectomy or open approach - Postoperative adjuvant therapy during protocol-defined follow-up (12 months) - Major comorbidities (e.g., NYHA class III/IV heart failure, eGFR \<30 mL/min/1.73m²) affecting outcome assessment - Concurrent enrollment in interventional clinical trials - Investigator-determined ineligibility based on risk-benefit analysis Always talk to your doctor about whether this trial is right for you.
