NanoKnife® / Irreversible Electroporation (IRE)

Precision Treatment for Localized Prostate Cancer

NanoKnife®, also called Irreversible Electroporation (IRE), is a minimally invasive focal therapy designed to target prostate cancer while preserving surrounding healthy tissue. Unlike surgery, radiation, or heat-based ablation, NanoKnife uses short electrical pulses to create tiny openings in cancer cell membranes, causing the cells to die naturally over time. Because it is non-thermal, important nearby structures such as nerves, blood vessels, and the urinary sphincter may be better protected.

Many patients choose NanoKnife because it focuses treatment only on the cancerous area of the prostate, with the goal of reducing risks of urinary incontinence and erectile dysfunction compared with whole-gland therapies.


How NanoKnife Works

NanoKnife does not use heat or freezing. Instead, electrical pulses disrupt cancer cell membranes while minimizing damage to nearby structures.



Common Side Effects & How We Reduce Risk

Most side effects improve over days to weeks. Because NanoKnife avoids thermal injury, surrounding nerves and blood vessels may be better preserved.

Patient reports commonly describe minimal post-procedure pain and rapid recovery, with the urinary catheter being the most common temporary inconvenience.


Follow-Up Protocol

Careful follow-up is essential after focal therapy.

PSA Monitoring

  • PSA every 3–6 months
  • Expected PSA reduction after treatment
  • Long-term PSA trend monitoring

MRI Surveillance

  • Multiparametric MRI at approximately 6–12 months
  • Evaluates treatment zone and checks for recurrence

Follow-Up Biopsy

  • Targeted biopsy may be recommended after treatment
  • Helps confirm successful cancer ablation

Ongoing Monitoring

  • Continued surveillance with imaging and PSA testing
  • Additional treatment options remain available if needed

FAQs about Nanoknife

No. NanoKnife is a minimally invasive focal therapy performed with needles rather than surgical removal of the prostate.

Most patients require a temporary urinary catheter for several days after treatment.

Many patients return to normal light activities within a few days and resume regular activity within 1–2 weeks.

Yes. Because it is focal and tissue-sparing, repeat treatment may be possible if new cancer develops.

NanoKnife is generally considered for carefully selected patients with localized prostate cancer. MRI findings, biopsy results, PSA levels, and tumor location all help determine candidacy.
