I’m about 95% confident in this answer…I hope that this does more good than harm…
Your second question first: Capsular incision (CI) refers to the urologist transecting either benign or malignant prostatic tissue, where the edge of the prostate in this region is left within the patient. In other words, the surgeon cut across the prostate itself during the procedure.
Was it iatrogenic? Certainly it was inadvertent. It happens...although more commonly in obese patients, or with inexperienced surgeons…all part of the learning curve. The apex is the most common location for a capsular incision because it is hardest to access. Would you care to comment on either your BMI or your knowledge of your surgeon’s experience level performing RPs? Perhaps it will difficult to get a clear picture of exactly what happened on the operating table at this point…although the surgeon will certainly have an answer for you when you ask him about it.
If tumor was transected, it appears that that could have an unfavorable impact on outcome (see THIS report); but if benign tissue only was at the margin, it seems that the outcomes are less clear…but probably not so much of an issue.
I’m not sure what your question means, “Could this positive margin be an artifact?”
Your first question was what “focal” means. A focal positive margin is a small area which “just touches the edge.” The opposite of focal in this regard is “extensive” which covers a large area.
