Narrowness of the bladder

I would like to know if I can continue to cysytoxcopy with dilation every year or there is a specialty surgery to fix the narrowness if the bladder 

Yes I had to have mine stretched the doctor told me this when I went back for a follow up and I am happy he did it now I don't go as much like I was doing once he does cystoscopy he can fix that while your asleep my procedure only lasted 20 minutes.
