 This study aims to investigate the effect of robot-assisted laparoscopic kidney transplantation on kidney injury by measuring biomarkers of kidney injury which are found in blood and urine to establish if there is a significant difference between robotic and open surgery. The study will also investigate the potential benefits of minimally invasive surgery on the surgical trauma associated with open surgery by assessing the surgical stress response between groups of kidney transplant patients receiving either open or minimally invasive kidney transplants and by comparing wound healing with patients undergoing donor nephrectomy.
