Background: The aim of this study is to assess the extent of the increased intracranial pressure resulting from lateral decubitus and 45 degrees downward positioning using sonographic optic nerve sheath diameter (ONSD) in patients undergoing laparoscopic transperitoneal nephrectomy. In addition, we evaluated the effect of the carbon dioxide pneumoperitoneum (CO2PP) on ONSD.
