Prostate Seed Implant

Prostate Seed Implant

A typical prostate seed implant takes approximately 1.5 hours. During the procedure, with the patient under either spinal or general anesthesia, the urologist uses tiny needles to place multiple tiny (5mm- about the size of a grain of rice) seeds in the man's prostate gland. The radiation oncologist assists the urologist in directing the placement of the seeds.

Using special ultrasound equipment allows  placement of the seed exactly where it should be.  Each seed emits a sphere of radiation about 1cm wide, and by placing the seeds properly, we can treat the entire prostate.

Because of the specialized placement of seeds and careful treatment planning, it is possible to give higher doses of radiation to the prostate, without affecting the rectum. External beam radiation, while effective in some cases (and sometimes used in addition to seed implants), may cause irritation of the skin and rectum.
