I've read or seen a video by NxThera explaining in "dumbed-down" terms how the Rezum process works to kill cells in the target tissue. I recall some remark about it being inherently safe because the steam could not pass from one zone of the prostate to another.
My question is if by "zone" they meant transition zone, central zone, or peripheral zone, does a steam injection in the transition zone (lateral lobe) not risk damaging ejaculatory ducts or other vital parts needed to retain full sexual function that exist in that zone? When injury does occur in areas not intended to be necrotized, what is the mechanism or cause? Did the urologist get too close with the injection point?
Asked another way, when the urologist injects the 9 second blast of steam, how does he/she control or limit the region of tissue through which it penetrates and subsequently causes cell death when it releases the heat of condensation? Do they really know how far it will propagate from any given injection point?
This is the only thing that spooks me about Rezum...imprecise control over the tissue that is necrotized.
I would appreciate any insight that anyone has on this question.
