Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Single (Investigator)

Detailed Description

By enrolling patients with renal tumors adapted to enrolled criteria, this study will document for the first time the safety and the short and long term efficacy of percutaneous or intraoperative IRE for renal tumors .


  • Procedure: irreversible electroporation
    • Percutaneous (CT-guided and/or US-guided) or open IRE with voltage in level B for renal tumors

Arms, Groups and Cohorts

  • Experimental: Group A
    • irreversible electroporation with voltage in level A for renal tumors
  • Experimental: Group B
    • irreversible electroporation with voltage in level B for renal tumors
  • Experimental: Group C
    • irreversible electroporation with voltage in level C for renal tumors

Clinical Trial Outcome Measures

Primary Measures

  • adverse effects
    • Time Frame: 1 month
    • adverse effects measured by such as abdominal bleeding, continuous abdominal pain, renal failure, et al.
  • Quality of Life (QoL)
    • Time Frame: 2 months
    • Quality of Life assessed as WHOQOL-BREF.
  • procedural compliance
    • Time Frame: 3 months
    • compliance will be analyzed by 3 months of follow-up post procedure.

Secondary Measures

  • Recurrence rate
    • Time Frame: 12 months
    • efficacy assessment by percentage of lesions that show no sign of recurrence 12 months after the initial IRE procedure) of IRE for renal tumor via cross-sectional imaging and pathological examination.
  • Voltage (A minimum and maximum range of voltage for safe and effective IRE)
    • Time Frame: 3 months
    • A minimum and maximum range of voltage for safe and effective IRE will be analyzed for optimal choice.
