Using the Off-Clamp and Sutureless Method in Robot-Assisted Partial Nephrectomy for Kidney Tumors Up to 7 cm

What this Trial Is About

Researchers are studying a new surgical method called the off-clamp sutureless technique for removing small kidney tumors less than 7 cm. This approach aims to preserve kidney function by avoiding clamping of the renal artery and using special techniques to control bleeding instead of traditional stitching. Current evidence mainly comes from smaller, retrospective studies focused on tumors smaller than 4 cm, so this study seeks to provide stronger data for larger or more complex tumors. The study involves patients undergoing robot-assisted partial nephrectomy using the off-clamp sutureless technique. During surgery, the renal artery is not clamped, and the tumor is removed with a small margin. Bleeding is controlled with electrocautery and hemostatic agents instead of sutures. This approach is designed to minimize damage to healthy kidney tissue and simplify the surgical process. Participants will be monitored for kidney function three months after surgery, measuring glomerular filtration rate GFR in both kidneys. Researchers will also track complications within one week after surgery and measure blood loss during the operation. The study includes detailed imaging and assessments before and after surgery to evaluate safety and effectiveness. The total participation period includes surgery and follow-up visits to assess recovery and kidney health.
