Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This is a prospective, human, in-vivo study among 20 patients presenting with solid enhancing SRM on cross sectional imaging suspect for renal cell carcinoma (RCC). Preoperatively, imaging is required through Magnetic Resonance Imaging (MRI), Contrast-enhanced ultrasound (CEUS) and contrast-enhanced Computed Tomography (CT). Furthermore, serum creatinine levels and VAS scores are obtained. A biopsy of the SRM will be performed in preoperative setting. IRE ablation will be performed using CT-guidance and ablation success will be measured directly after the ablation through contrast-enhanced CT. Device related adverse events (AE) will be registered using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 guideline. One week post ablation only CEUS and MRI will be performed to limit exposure to ionizing radiation. At 3 months, 6 months and 12 months post ablation CEUS, MRI and CT will be performed. Additionally, at these time points serum creatinine levels and VAS scores will be obtained, and quality of life will be assessed through SF-36 questionnaires. Residual and recurrent disease will be assessed through tissue enhancement on cross sectional imaging.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Irreversible electroporation (IRE)
IRE is based on high current electric pulses, transferred between two or more placed needle electrodes. Charging the cell membrane causes holes in the cell membrane called "nanopores", resulting in increased permeability of the cell and subsequent cell death.
Irreversible Electroporation
Guided by CT and accompanied by an external spacer for fixation, needle electrodes will be placed. The amount of probes and probe placement will be attuned for specific tumour size and location, granting 15mm between the electrodes with an active tip length of 15mm. IRE pulses with pulse intensity of 1500 V/cm will be delivered in 90 consecutive pulses of 90µs.
