As with any surgical procedure, incision of bladder stenosis can have dangers and complications. General dangers of medical intervention, such as infections, post-bleeding, etc. may also occur in case of this intervention as well. The chances of developing complications are greatly influenced by what previous bladder surgeries have taken place.
After surgery, the previously incised area may become scarred, and other areas of the urethra may narrow, necessitating further surgery.
However, the frequency of complications is negligible relative to the number of surgeries performed.
