When can HIFU treatment for prostate be used?
Although Tratamiento del cáncer de vejiga is apparently less risky and non- invasive, there are certain cases and parameters when HIFU can be applied for treating prostate cancer.
- Useful for treating solitary tumors or a part of large tumors. This infers that the same cannot be used for treating cancer that has spread outside the prostate.
- Can be used for newly diagnosed tumors.
- Can be used for recurring prostate cancer.

- Diabetic patients can be treated too.
- Even Cardiac patients can avail this surgery.
- Can be used along with hormone therapy.
- Includes zero or minimal injury to rectum
- Zero radiation exposure
- Very less bed- rest time and operating time.
How long does HIFU treatment take?
HIFU surgery takes merely 2 to 3 hours for the actual proceedings. Except that, a patient is required to set aside a complete day for the surgery, inclusive of the pre and post operational care. Before the treatment, the patient is examined by an urologist, a member of the anesthesiology staff and a nurse involved in the treatment plan. This can take approximately one and a half hour to two hours. Then the surgery will last for approximately 3 hours and the recovery will require four hours.

HIFU treatment is performed by a urological surgeon trained in HIFU technique and involves the following steps-
Preparing the case history- The medical history of the patients is studied by anesthesiologist prior to giving any anesthesia. Those patients, who have a cardiac problem history, have to forward their blood work and electrocardiograph in advance of the treatment.
Anesthesia- HIFU treatment involves the use of spinal anesthesia for which is an intravenous sedative. The anesthesia is quite important as the patient remains comfortable throughout the treatment.

Mapping- After giving the anesthesia, the urologists need to decide how much time will the surgery take and which areas need to be treated. For this they map the size of prostrate.
High intensity waves- After the mapping of prostate, a probe is placed in the rectum which emits beam of high intensity focused ultrasound. Approximately 400 to 600 pulses of high intensity ultrasound waves are sent through the rectal wall accurately centered on the prostate. This focusing generates intense heat and causes the destruction of the tissue inside the targeted zone without damaging surrounding tissues.
