March 16, 2009 -- Question: What is post-seed implant edema?
Answer: Post-implant edema means swelling of the prostate following a seed implant. As one can imagine, by placing needles and radioactive seeds into the prostate, the tissue itself can swell up. We can reduce the probability of swelling by prescribing medication following the procedure. The swelling typically maximizes anywhere from four to six weeks post-implant, and the symptoms typically do not last for a prolonged period of time.
