Liaoning Tumor Hospital & Institute

The goal of this clinical trial is to learn the evidence-based medical value of 3D visualization techniques to improve tumor control, preservation of renal function, and perioperative safety in robot-assisted nephron sparing surgery for complex renal tumors. The main question it aims to answer is:
Is 3D visualization techniques more effective in improving robot-assisted nephron sparing surgery for complex renal tumors in terms of tumor control, renal function preservation, and perioperative safety.
The researchers will randomize participants into a 3D trial group and a conventional group for comparison.
Participants will:
Complete Blood routine, liver and kidney function tests on the first and third day after operation.
Have Renography at 3 and 12 months after the operation. Cooperate with follow-up visits.
