Robot Surgery for Small Kidney Tumors Without Stitches

This trial is testing a new surgical technique for removing small kidney tumors (7 centimeters or smaller) using robot-assisted surgery. The approach being studied avoids clamping off the kidney's blood vessels during surgery and replaces traditional stitching with newer methods to control bleeding. The goal is to preserve as much healthy kidney tissue as possible and maintain kidney function after surgery.

Standard kidney tumor removal surgery requires clamping blood vessels and using complex multi-layer stitching, which can damage healthy kidney tissue and cause loss of kidney function in up to 30% of patients. This trial exists to see whether the newer approach—skipping the blood vessel clamp and using alternative bleeding-control methods—can be safer and preserve kidney function better.
