Robot assisted transperitoneal laparoscopic pyeloplasty

Nowadays,with laparoscope techniques increasinglydeveloped its indications are covering morecomplicated medical fields.Moreover,as a camera holder,the robotic system of an automated endoscopic system foroptimal positioning（AESOP）can be controlled directlyby the surgeon’s voice.It can be more effectivelymanipulated and more accurately control the videoendoscope,which enables the unification of theoperator’s thoughts and visual field and decreases theinadvertent movements from a human assistant.It alsoimproves the learning curve for complicated minimallyinvasive procedures.Between April 2003 andDecember 2005,25 patients with ureteropelvic junction（UPJ）stricture underwent robot assisted transperitoneallaparoscopic pyeloplasty.
