High Intensity Focused Ultrasound (HIFU) for the Ablation of Prostate Tissue
The prostate is a small gland in the male reproductive system. It is situated in front of the rectum, below the bladder, and surrounds the urethra, which is the tube through which urine flows out of the body. The main function of the chestnut-sized prostate is to secrete part of the seminal fluid that combines with sperm to form semen. A healthy adult prostate weighs around 20 to 25 grams and is approximately 4 cm wide, 3 cm high and 2 cm thick. It can be affected by various diseases including cancer that can be detected by medical exam and blood PSA (prostate-specific antigen).
