Abstract
During the last two decades the field of urology has seen a tremendous growth in minimally invasive surgery. Potential advantages with this shift toward laparoscopic surgery include smaller incisions, reduced blood loss, less post-operative pain with reduced intake of narcotics, shorter hospital stays, and faster recovery. Nephrectomy, adrenalectomy, pyeloplasty, and prostatectomy have all established themselves as procedures benefitting from minimally invasive surgery. Complex laparoscopic procedures, for example prostatectomy, have proven to be quite a daunting task, because of the steep learning curve for many urologists [1]. Factors limiting the performance of standard laparoscopic radical prostatectomy are counter-intuitive motion, the lack of depth perception secondary to 2D vision, and rigid instrumentation with only four degrees of surgical freedom. These factors hinder visualization, dissection, and suturing in small spaces [1]. Introduction of robotic technology into modern day surgery has removed many of these technical barriers and has the potential to facilitate the broad-based adoption of complex laparoscopic procedures. There are more than 400 robotic systems in the USA and over 30,000 robotic procedures have been performed (communication with Intuitive Surgical). Although, initially, the equipment was conceived for use in cardiac surgery, adoption has been strongest in urology. It seems that robotic surgery has been uniquely adapted to urology, especially prostatectomy, because of the unique advantage of miniature instruments in the pelvis. Although prostatectomy is the main use of robotic surgery in urology its use in other urologic procedures is expanding rapidly as surgeons become more adept with its use. We review the current status of robotic technology, the constraints to its use and the surgical applications of robotic technology in urology.
