In experienced hands, laparoscopic pyeloplasty is an effective alternative treatment for symptomatic ureteropelvic junction obstruction (UPJO). Although laparoscopic surgery can clearly benefit patients, laparoscopic pyeloplasty using conventional instrumentation is complex. The purpose of this report is to evaluate the feasibility of robot assisted laparoscopic surgery. Eleven pyeloplasties for UPJO were performed via a laparoscopic transperitoneal approach exclusively with the da Vinci Surgical System. The mean procedure time was 197 min (range 110-310 min). All operations were completed laparoscopically with no intraoperative complications and negligible blood loss. All patients recovered rapidly after surgery with excellent functional results at the 1 year follow-up. Our initial experience suggests that robot assisted Anderson-Hynes pyeloplasty is a safe and effective alternative to conventional laparoscopic surgery. In our opinion, robot assisted surgery will allow urologists to perform complex procedures with greater precision, confidence, and better results, as well as enable them to adapt the whole spectrum of laparoscopic procedures to their field.

Advanced robotic surgery was first introduced into urology in 2000. The first studies showed the feasibility and safety of the daVinci (Intuitive Surgical Inc., Sunnyvale, CA) telemanipulator assistance in radical prostatectomy, pelvi‐ureteric junction obstruction, and radical cystectomy and neobladder formation. The miniature endowristed tools offer a potential advantage over standard laparoscopy in the accuracy of preparation and suturing. Other features are a three‐dimensional vision system and unimpaired hand‐eye coordination. Complex laparoscopic tasks are learned faster by using the robot, which may also explain the shorter training required for radical prostatectomy than for manual laparoscopy. This new and expensive technology has spread rapidly over the last 4 years. By 2004, ≈ 10% of radical prostatectomies in the USA will be robot‐assisted. Data on the functional and oncological outcomes are accruing but not yet conclusive. There will be a further spread of robotic surgery, routine telesurgery, smaller and more affordable systems, the introduction of virtual reality, all developments which have the potential to urological surgeons to improve.
