bph question

I have seen a urologist for the past two years re my bph problem. I have been on flomax for symptoms but now the bph has progressed to the point where I can no longer live with the constant frequency, inability to empty, etc.  My urologist suggested that I have a Turp.  He has informed me that "most" patients have fewer symptoms after the procedure once recovery is complete.  He informed me he would use a knife rather than a lazer because of the size of the hyperplastic tissue.  I'm feeling uneasy about the whole thing and my doctor does not provide me with info unless I specifically ask him a question.  Is there a way that I can confirm that what he recommends is the standard of care for this procedure and how can I find out if this doc is a good one?
