ABSTRACT

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, approximately 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.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: Laparoscopic radical prostatectomy is a complex procedure and has been standardized only during the last years. The remote controlled da Vinci Surgical System has opened up a new era in minimally invasive surgery. We here present our initial experience with the translation of open retropubic radical prostatectomy to laparoscopic technique using da Vinci and a one year follow-up. METHODS: After a period of technical development and training on cadavers, 40 consecutive patients eligible for radical prostatectomy were treated. After port placement, the urologist took control of the 3D 30 degrees laparoscope and the two instrument arms at the da Vinci remote console to perform bilateral pelvic lymph node dissection, radical prostatovesiculectomy and urethrovesical anastomosis. RESULTS: The procedure was completed laparoscopically in all but two patients. Mean procedure time was 8.3 hours and mean intra-operative blood loss 570 ml. Learning curves associated with the use of the da Vinci Surgical System show that there is a 22-minute decrease in time required to perform the radical prostatectomy and lymphadenectomy for each case (p<0.0001). Patients recovered rapidly after surgery with early oncological and functional results that were similar to those obtained with our standard radical prostatectomy technique. CONCLUSIONS: Remote controlled robotic surgical systems are useful to translate open retropubic radical prostatectomy to laparoscopy. This new technology has the potential to equip the urologist with the microsurgical precision needed to preserve the delicate structural integrity of the pelvic floor in order to improve functional results without compromising the oncological outcome.

ABSTRACT

BACKGROUND AND PURPOSE: Laparoscopic adrenalectomy is considered the standard method for removal of benign adrenal tumors. Although laparoscopic surgery provides clear patient benefit, laparoscopic adrenalectomy using conventional instrumentation is complex. Our objective was to evaluate whether the da Vinci trade mark Surgical System, a comprehensive robotic endoscopic surgical device, could be used effectively to perform laparoscopic adrenalectomy. PATIENTS AND METHODS: Through a transperitoneal approach, three right and one left adrenal tumors were removed in four patients using this method. RESULTS: There were no complications, and the clinical results were excellent. CONCLUSION: We demonstrate the feasibility of performing laparoscopic adrenalectomy exclusively by using robotic telepresent technology from a remote workstation. The da Vinci System enables conventionally trained urologic surgeons to perform complex minimally invasive procedures with ease and precision. Therefore, we are convinced that the system helps the urologist to adapt the whole spectrum of laparoscopic procedure in this field.
