The hifu treatment is delivered through a specialized probe inserted into the rectum using a process very similar to light being focused onto paper with a magnifying glass. From the probe, a high intensity ultrasonic beam is focused onto the prostate through computer control along with simultaneous ultrasound imaging to identify the prostate.
In this process the prostatic tissue,including the prostate cancer is heated to about 90 degrees Celsius and destroyed. Organs and tissue adjacent to the prostate are unharmed. The destroyed prostatic cancerous tissue is eventually expelled during urination.
Initially,the patient is put to sleep and a needle-trocar suprapubic catheter is inserted into the bladder in the lower abdomen. This form of urinary bladder drainage is preferred and tolerated much better than a catheter through the penis.
The man’s legs are then placed in stirrups and the HIFU probe insert ed into the rectum.
The HIFU procedure is commenced and usually takes 2-3 hours to complete.
After an hour or so in the recovery room, the patient walks out off home.
