Discuss this procedure only with a qualified doctor, an urologist!
He will give you all the pros and cons and will confirm there are no incisions necessary.
However, be careful with your choice of your doctor. Ask him bluntly how many times he did it last year. Since it is a new way for BPH it requires a lot of experience.
I'm not sure about the price. My research said 300-400 th Baht in Chiangmai
