This is a German registry that collects detailed information from patients who undergo kidney-sparing surgery for kidney tumors. Researchers want to understand how different surgical approaches — open surgery, minimally-invasive surgery, and robotic surgery — affect patient outcomes and long-term kidney function. By gathering real-world data from many patients, doctors hope to better understand which surgical approach works best for different types of kidney tumors.
Most patients diagnosed with kidney cancer today have early-stage disease that can be treated with kidney-sparing surgery. However, doctors have limited real-world information comparing different surgical approaches, especially newer techniques like robotic surgery. This registry aims to fill that gap by collecting detailed outcome data to help doctors choose the best surgical approach for each patient.

If you enroll, your surgical team will collect information about your surgery, any complications, and your kidney function. You will be asked to complete follow-up questionnaires at specific time points — at 30 days, 12 months, 24 months, and 5 years after surgery — to track your long-term kidney health and overall health. The registry simply documents what happens during your standard surgical care and follow-up.
