A Study of 3D Visualization Techniques to Improve the Quality and Safety of Robot-assisted Nephron Sparing Surgery for Complex Renal Tumors.

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.
