This study aimed to evaluate the increase of intraabdominal pressure 12- 14 mmHg caused by pneumoperitoneum resulted from carbon dioxide (CO2) insufflation induce glycocalyx endothelial injury that cause kidney tubular injury on live donor patient that undergo laparoscopic nephrectomy surgery, and decreasing the intraabdominal pressure to 8-10 mmHg during surgery is expected to reduce the injury.
