Single-layer Robot-assisted Transperitoneal Retroperitoneal Tubeless Radical Nephrectomy

This study is comparing different surgical techniques for robot-assisted laparoscopic (keyhole surgery) removal of the kidney — specifically, it is evaluating a single-layer closure technique versus a multi-layer technique for repairing the abdominal wall after surgery, looking at recovery, complications, and outcomes. **You may be eligible if...** - You require surgical removal of a kidney (radical nephrectomy) for any medical reason - You are healthy enough to undergo laparoscopic (minimally invasive) surgery - Your blood pressure and blood sugar are controlled before surgery **You may NOT be eligible if...** - You are too unwell to undergo laparoscopic surgery for any reason - Your blood pressure or blood sugar is uncontrolled before the operation - You only have one functioning kidney (solitary kidney or the other kidney does not work) - You need surgery on multiple organs at the same time Talk to your doctor to see if this trial is right for you.
