Urinary tract scarring following radical prostate surgery.

age=73. Generally good health. 6'2' , 188 lbs. High PSA test 2/10, decided to go conventional open surgery. 10 days after release from hospital developed hemotoma, Dr. reopened, vac. treated 2 months, now healing with bandage.
Developed urinary restriction with moderate pain. Urologist inserted camera/wire through penis (very painful) and removed some scarring that allowed full flow w/ no pain. 3 weeks later (currently) restriction returning. Are there any alternatives, i.e. stint or whatever to permanently fix? Must I be awake during procedure as before?
Thank You
