I am not a urologist
I presume we are talking about benign prostatism
The treatment is simple - remove a core to stop the obstruction. The urololgists I know have not been impressed with green light because of high recurrence. They prefer to remove under direct vision. I know little about Holep but would be suspicious it may be similar
The best advice is to ask your GP who he would go to and then ask that urologist what he is happiest with. Far better to have the guy strutting his normal stuff than to be experimenting or struggling with something he is less familiar with
This is a routine operation. Go to the guy who does lots of them and you will be giving yourself the best chance of success
