Outcome Measures

Primary Outcomes (4)

  • Recruitment Potential

    Rate of accrual \[participants per month\]

    Study duration (2 years)

  • Suitability of secondary outcome measures

    Assess the feasibility of collecting all secondary outcome data. To be assessed qualitatively by the study team and by calculating the proportion of patients with each data point completed.

    Study duration (2 years)

  • Resource Utilization - Operating Room/Robotic Studio Time Availability

    Assess the capacity of accommodating surgical time for a full scale clinical trial. Measured by time from decision to treat to surgery date.

    Study duration (2 years)

  • Resource Utilization - Cost of Study Participation

    To develop an accurate budget for a full trail, we are assessing the average cost of running the trial per patient, per arm. This calculation will include: cost of study coordinator time (number of hours x hourly wage), additional cost of robotic disposables, and cost of additional testing outside of standard of care.

    Study duration (2 years)

Secondary Outcomes (13)

  • Operative Time

    Duration of surgery

  • Warm Ischemia Time

    Duration of surgery

  • Blood Loss

    Duration of surgery

  • Conversion rate to radical nephrectomy or open partial nephrectomy

    Duration of surgery

  • Length of Stay

    1-7 days

  • +8 more secondary outcomes
