Intra-operative Trans-rectal Ultrasound Guidance for Robot-assisted Radical Prostatectomy (TRUS-RP)
Radical prostatectomy, or the surgical extirpation of the prostate, is a standard treatment for prostate cancer. The state of the art radical prostatectomy involves a robotic laparoscopic surgery system (the da Vinci) which provides the surgeon with excellent 3D visualization of the surgical site and improved dexterity over standard laparoscopic instruments. While the long term prognosis of prostate cancer patients who undergo radical prostatectomy has improved significantly over the past two decades, there remain significant rates of disease recurrence and complications.
The investigators hypothesis is that advanced trans-rectal ultrasound (TRUS) imaging can be deployed and used easily during surgery, can be registered to the robot coordinate systems with high accuracy, and can be controlled from the surgeon's console, in order to improve the visualization of the prostate and peri-prostatic anatomy, and in order to produce a cancer probability map that can be used to make decisions on surgical margins.
The investigators objectives are
- To demonstrate that TRUS imaging can be integrated with the da Vinci radical prostatectomy
- To determine the ability of TRUS imaging to intra-operatively visualize the prostate and peri-prostatic tissue from the surgical console
This is an observational study; trans-rectal ultrasound will be used to visualize the prostate and periprostatic structures during surgery but the standard of care will not be affected by this ultrasound imaging.
