Nowadays, with laparoscope techniques increasingly developed its indications are covering more complicated medical fields. Moreover, as a camera holder, the robotic system of an automated endoscopic system for optimal positioning （AESOP） can be controlled directly by the surgeon＇s voice. It can be more effectively manipulated and more accurately control the video endoscope, which enables the unification of the operator＇s thoughts and visual field and decreases the inadvertent movements from a human assistant. It also improves the learning curve for complicated minimally invasive *** April 2003 anti December 2005, 25 patients with ureteropelvic junction （UPJ） stricture underwent robot assisted transperitoneal laparoscopic pyeloplasty.
