This treatment causes an increase in volume due to the heating of the prostate tissue. A catheter is then placed through the urethra for a few days to ensure urination.
Not every patient with prostate cancer can be treated with this therapy. Ideally, it should be a well-recognizable and localized change in a simultaneously less aggressive tumour located exclusively in the prostate. Patients with diseases of the rectum are excluded by the necessary probe placement usually from such a therapy. Focal treatments are always a middle ground between radical therapy (surgical removal of the entire prostate or radiation) and watchful waiting. The cancer is not fought with all means maximally, but is to be treated and controlled completely purposefully. Benefits lie in a lower risk of unwanted side effects with a mostly good quality of life. HIFU therapies have a shorter duration of treatment with a 2-3-day hospital stay.
