I had 2 sessions HDR Brachytherapy last June at Mayo/Rochester by Dr. Wilson. I had the choice of HDR Brachytherapy or the 5 treatment of proton therapy. I chose HDR Brachytheapy with 2 treatments since it reduced my travel. The studies show it has the lowest incidence of recurrence of all of various treament options. Side affects consisted of fatigue for a couple of days following the treament but I was back to my regular exercise routine within 5 days following each treatment. The doctor had me take flomax for 30 days which was helpful but I may of been able to go without. I did develop ED which can happen with all of the various treatment options, the meds do work for this. Mayo has a lot of experience with HDR, however the proton is favored for many patients since they do not have to be put under. There are not many centers that do HDR Brachytherapy since there are not many RO that are trained in this and the additional physic team is needed as well. Prostate Cancer Research Institute (pcri.org) has some good videos on HDR brachytherapy as well.

Dr. Waddle was who I had for my HDR Brachytherapy. He was excellent. I was told he does the second most of this treatment at Mayo Rochester and that one other does more than him. I was comfortable enough after hearing that and having met him to proceed. Hope this helps. Good luck with your decision.
