Cryaoablation Assisted Partial Nephrectomy a Non Ischemic Approach

This study is testing a new surgical approach for removing kidney tumors using cryoablation (freezing) to reduce bleeding during the operation — a technique called cryoablation-assisted partial nephrectomy. The goal is to preserve as much of the healthy kidney as possible while avoiding the need to temporarily cut off blood supply during surgery. **You may be eligible if...** - You are between 45 and 90 years old - You have a kidney tumor that is 7 cm or smaller - More than half of the tumor protrudes outside the kidney (exophytic) **You may NOT be eligible if...** - You have had prior surgery on the same kidney - Your cancer has spread beyond the kidney (metastatic disease) Talk to your doctor to see if this trial is right for you.
