Prostiva® RF Therapy

Prostiva® RF Therapy (Prostiva) is a safe, effective, in-office treatment that that provides long-term relief from BPH symptoms and urinary obstruction. Prostiva is appropriate for men experiencing moderate to severe BPH symptoms especially patients who do not want to take daily medications for the rest of their lives, dislike the side effects and ongoing costs of medication or do not want the risks, side effects or high costs of surgery.

Because it provides direct visualization of the anatomy during the procedure, Prostiva treats the median and lateral lobe as well as asymmetrical prostates.  Here are some examples of prostate shapes that Prostiva® RF Therapy can treat:

 

How Does it Work?

Prostiva® RF Therapy treats BPH utilizing low level radio frequency energy to destroy enlarged prostate tissue. The movement of the electrons causes the tissue to heat.  One reason RF energy has been so effective in forming precise and controlled lesions is the existence of a phenomenon called current density. Current density is the amount of current flowing out of the surface area of the conductor. As the current is emitted from the needle electrodes, the energy is concentrated along the small exposed surfaces of the electrodes, creating a very high current density at the electrode surface. The energy quickly dissipates as it leaves the needle electrodes on its path to the grounding pad. This produces predictable and repeatable lesions, which are located directly around the electrodes. The Prostiva® RF Therapy procedure helps to reduce the constriction of the urethra and relieve BPH voiding symptoms.

“After performing over 3000 TURP’s I began doing Prostiva RF therapy. Having now treated over 1100 patients with Prostiva RF therapy I am extremely pleased with my results, and my patients are very happy.” – James W Young III MD

Benefits

  • Durable results – reintervention not necessary in over 86% of patients at five years1
  • Low rate of side effects1
  • Established reimbursement

Risks

As with all medical procedures, there are some risks involved with this procedure. 2

  • Obstruction (blockage)
  • Bleeding
  • Pain/discomfort
  • Urgency to urinate
  • Increased urinary frequency
  • Urinary tract infection

Clinical Results

Prostiva® RF Therapy has currently has currently treated over 100,000 patients worldwide and there have been at least 75 published articles on RF Therapy for BPH. For a complete overview of the Prostiva® RF Therapy clinical data, please go to our Clinical Results page.

Increased Necrosis, Greater Durability3,4

It’s proven.  More tissue necrosis equates to a better long-term outcome for patients.  Tissue necrosis is a function of time and temperature.  50°C is required to produce tissue necrosis in 60 minutes, higher temperatures produce a larger volume of necrosis in less time.  Treatment times at temperatures below injury threshold produce no irreversible damage.  Prostiva® RF Therapy reaches intraprostatic temperatures of 110°C allowing it to create a lesion in the tissue in just two minutes and 20 seconds.
