Brief Summary:

The objective of the study is to examine the effectiveness and accuracy of the BioXbot in prostate biopsy as opposed to transrectal biopsy. This evaluation of the efficacy of both the procedures is based on:

  • Uptake rate
  • Peripheral zone reachability
  • Needling accuracy
  • Procedure execution time
  • Post operative discomfort or trauma experienced by patient
  • Quality and type of tissue sample extracted
  • Adverse and unanticipated side-effects on patient after the procedure and recording any unexpected reactions

Arm Intervention/treatment
Experimental: Transperineal Biopsy
Biopsy of the prostate using transperineal approach
Procedure: Robotic Transperineal Biopsy
Saturation biopsy for previous negative patients

Primary Outcome Measures :
  1. Cancer Detection [ Time Frame: 2 years ]
    to detect any undetected cancer in Patietns undergoing saturation biopsy

Secondary Outcome Measures :
  1. Accuracy and Repeatability [ Time Frame: 6 months ]
    To be accurate in biopsy position (+/- 2mm) and be able to go back to the same position if patient undergoes treatment.
