Current Primary Outcome Measures  ICMJE
 (submitted: August 15, 2016)
  • Number of patients with treatment-related adverse events [ Time Frame: 1.5 years ]
    The PI will contact each participant approximately one week after their biopsy to ask if they have experienced any adverse events due to the study device. If all 5 participants complete the procedure and fail to report any adverse events, the device will be considered safe for use during biopsy.
  • Number of patients for whom the study-related procedures can be completed in less than 30 minutes [ Time Frame: 1.5 years ]
    The amount of time to complete the study-related portion of the biopsy will be noted. If the study-study portion of the biopsy is able to be completed in less than 30 minutes for each of the 5 participants, then the device will be considered feasible for use during biopsy.

Descriptive Information
Brief Title  ICMJE Transrectal Ultrasound Robot-Assisted Prostate Biopsy
Official Title  ICMJE Transrectal Ultrasound Robot-Assisted Prostate Biopsy
Brief Summary The commonly used diagnostic procedure for prostate cancer, a transrectal ultrasound (TRUS)-guided biopsy, has significant limitations. Freehand biopsy cores are often spatially clustered, rather than uniformly distributed, and do not accurately follow the recommended, sextant template. In addition, a freehand TRUS-guided biopsy does not allow precise mapping of the biopsy cores within the prostate. Therefore, it is nearly impossible to re-biopsy or target the exact cancer foci. As a result, most TRUS-guided prostate biopsies today are poorly targeted and their spatial mapping remains subjective.
Detailed Description This proposed feasibility and safety study of 5 patients attempts to improve TRUS-guided prostate biopsy by utilizing a novel robotic TRUS manipulator (TRUS Robot). A successful TRUS Robot guidance will provide crucial spatial information of the biopsy cores for improved prostate cancer detection, treatment, and monitoring. This proposed study is a proof of concept for a future protocol.
