I have had 3 strictures within 1 yr post RP and 1 which was real serious 9 years post RP
Two of them, urologist manually dilated and third had to do rotoroter. The last one I had was in Sept 2010.
Yes, it is possible to have strictures. Suggest Cystoscope and review by urologist.
In Sept had emergency superpubic catherization and it was not fun. ER. local small hospital, almost put me through ruff trying to put in catheter, finally urologist came in and had to do superpubic followed by Homa Laser removal.
The pain etc don't mess around, better to be sure no problem than problem - call your urologist for cystoscope.
