urethral strictures and reconstruction

My husband is experiencing problems urinating:  pain, blood, pressure, etc.  The urologist indicated that his urethra is being blocked by strictures or scar tissue from radiation treatment for prostate cancer.  He has had two cystoscopies within a month and a half to stretch the urethra.  His last one was this past week and the urologist left a catheter in place until tomorrow (6 days) in hopes that would help keep the urethra open.  What would be our next step?  We are thinking of urethral reconstruction.  We thought about a stent but read that, too, can cause scar tissue to form.  Any thoughts or suggestions would be greatly appreciated.  Needless to say, he is becoming a little discouraged.  We are just looking for a light at the end of the tunnel and some return to normalcy.

Thank you.
