A minimally invasive ablative technique called high-intensity focused ultrasound (HIFU) is a recently FDA-approved alternative to radiation or surgery for certain men with prostate cancer. For those who are eligible for the procedure, HIFU offers outcomes essentially equivalent to radiation, but with potentially fewer side effects.
HIFU waves energize localized tissues to about 80 degrees Celsius and cause a lethal tissue pressure drop of 20,000-30,000 bars, resulting in coagulative necrosis and tumor death. The new technique does so with robotic precision, offering a focal beam width of 1.7 mm, which helps minimize damage to healthy tissue and improve overall quality of life after treatment.1,2 The procedure relies on a computer-driven robotic-assisted technique, carried out under general anesthesia and delivered through a transrectal ultrasound probe. There are no incisions and no need for pain medication after treatment.
Advantages of HIFU
Throughout the procedure, the prostate gland is repeatedly imaged using a combination of real-time ultrasound and static multiparametric magnetic resonance imaging (mp-MRI). This provides surgeons with detailed information on tumor size and location, helping maximize disease ablation and sparing healthy surrounding tissue...
