Dr Patrick Walsh is best known for his pioneering work (25-years ago) in the development of what is formally known as "the anatomic approach to radical prostatectomy," which involves
nerve-sparing techniques that have reduced the probability of impotence and incontinence.
His surgery techniques radically changed things. Men with PC my grandfather's age (I'm mid-50's now) virtually all came out of surgery impotent, and very frequently incontinent. The nerve-sparing technique has incrementally evolved and improved since then, but his work was revolutionary.
He wrote a book which is widely considered a comprehensive overview for newbies, but lacks is many areas some of which have been mentioned here already. I think you've graduated beyond "newbie," Pratoman.
Perhaps more interesting is to understand Dr Walsh's contemporary perspectives...
In a big league (my phrase) panel discussion (with Drs. D'Amico, Carroll, Klotz and Walsh) on the topic of "Management of Early Stage Prostate Cancer," (like you have, Pratoman), at the 2010 AUA Meeting, Walsh famously commented:
"If you are going to do an unnecessary operation, it is important that you do it well."
Pick a good surgeon, Pratoman.
