Robotic technology and the translation of open radical prostatectomy to laparoscopy:: The early Frankfurt experience with robotic radical prostatectomy and one year follow-up

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 30degrees 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.
