Men with small tumors that are contained within the prostate.
High-Intensity Focused Ultrasound does not require surgical incisions and no overnight stay is needed. The patient will have an MRI in advance to help target the tumor location. During the procedure, an ultrasound probe is placed in the patient's rectum to deliver the high-intensity waves. A general anesthetic is used.
Practitioners are also exploring HIFU performed during an MRI, which allows more precise targeting of the tumor. MRI can also provide a temperature measurement of the tissue involved, ensuring that as little damage as possible is done to healthy cells.
Men may experience urinary incontinence or infection. Swelling may make it difficult to urinate and a catheter may be left in place for a few days. Erectile dysfunction can occur.
