HIFU - Out Patient Treatment

HIFU - Fast Recovery

Ablatherm Prostate Ablation

1.The patient lies down on his right hand side and stays in this position throughout the treatment.

2. This picture illustrates the position of the probe in relation to the rectum and the prostate (here in orange color).

3. Due to the closeness of the prostate to the rectal wall, the treatment is performed optimally using the transrectal approach.

4. The probe is lubricated and then inserted into the rectum via the anus. The prostate is then accessible for ultrasound ablation.

5. The imaging transducer in the middle of the probe allows a very precise three-dimensional reconstruction of the area to be treated and to be seen on a monitor.

6. The whole prostate is scanned and visible on the computer screen.

7. On the screen, the surgeon plans each step of the treatment with a microscopic precision.

8. Finally, the machine produces High Intensity Focused Ultrasound waves which destroy the cancer cells.

Treatment Strategy

Planning and Monitoring

Rectal Cooling System:

Temperature of cooling liquid is monitored in real time

External Movement Detection:

Patient's movements are monitored in real time

Rectal Wall Position Monitoring:

Rectal Wall is monitored in real time on the ultrasound image

Patient position:

right-hand side lateral decubitus

-pelvis placed along the lower and right edges of the table

-back placed at 30° (aid to compensate rectum anatomy) 

-straight back (prevent collapse of the upper back )

-knees lifted and angled on the leg support

Patient comfort:

-prevent any pressure point with agar cushions

-warm up the patient with blankets and/or heater)

 

Patient safety:

-support patient back, legs and foot with holds and straps

-ensure that patient is not moving during the entire treatment
