ABSTRACT
Answer: (d) Owing to the size of the peritoneum compared to the retroperitoneal space created by insufflation, a transperitoneal approach allows for a wider field of view and a larger working space. Additionally, a transperitoneal approach allows for easier access to other genitourinary structures compared to a retroperitoneal approach. Recent studies have failed to show a difference in operative time in a transperitoneal versus a retroperitoneal approach. A retroperitoneal approach does offer essentially direct access to the renal unit and, as the peritoneum is not entered, limits the risk of future adhesions.
