Which is the best treatment for urethral strictures after resection of prostate?

Work with Urologist: Your urologist should be able to help you with the strictures. I would expect they can dilate them periodically.

Dilation procedure.: You are probably going to need a dilation procedure. A tube inserted into the urethra of a larger caliber then the stricture which will dilate the area of he stricture. You can get numbing medicine so it's not as bad as it sounds. The real challenge is that you will need to have this procedure again and again as the area of the stricture "heals itself" and forms another stricture,
